This invention was made with government support under federal grant number IOS-1237880 awarded by the National Science Foundation. The government has certain rights in the invention.
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of the filing date of U.S. Provisional Application No. 61/728,654, filed November 20, 2012, and of the filing date of U.S.
Provisional Application No. 61/869,052, filed August 22, 2013 and claims priority to U.S.
Application No. 13/799,831 filed March 13, 2013. The entire contents of each of these referenced applications are incorporated by reference herein.
BACKGROUND
There are ongoing attempts to enhance yield and quality, as well as life span, of food crops and other plants, such as ornamental plants and trees, in an effort to use resources more efficiently and produce more food, flowers and trees. Additional approaches for doing so are still needed, and one of the primary targets for manipulating plant productivity is the flowering process and its corresponding effects on vegetative and reproductive shoot architecture.
SUMMARY
Described herein are novel genetic variants of Solanaceae plants, e.g., tomato plants, that (a) exhibit modified flowering time and shoot architecture; (b) exhibit higher yield, higher quality products (e.g., fruits); (c) produce products (e.g., fruits) with different compositions, (e.g., brix, also known as enhanced soluble solids or sugar concentration in the fruits,); or (d) any combination of (a) to (c), compared to corresponding "wild-type (WT)"
Solanaceae plants (Solanaceae plants that have not been genetically altered).
In one embodiment, a genetically-altered plant, such as a genetically-altered semi-determinate or semi-indeterminate Solanaceae plant, comprises a mutant suppressor of spl (sspl) gene and a mutant single flower truss (sft) gene. Such Solanaceae plants are heterozygous or homozygous for mutant genes (e.g., heterozygous or homozygous for a mutant suppressor of spl (sspl) gene or heterozygous or homozygous for a mutant single flower truss (sft) gene) or heterozygous or homozygous for both a mutant suppressor of spl (sspl) gene and a mutant single flower truss (sft) gene (double heterozygotes or double homozygotes). Such plants may further comprise a mutant self pruning (sp) gene. Such plants may be heterozygous or homozygous for a mutant self pruning (sp) gene.
Such plants can also be in the wild type SELF PRUNING (SP) background.
In a further embodiment, Solanaceae plants comprise a mutant self pruning (sp) gene and a mutant single flower truss (sft) gene. Such Solanaceae plants are heterozygous or homozygous for mutant genes (e.g., for a mutant self pruning (sp) gene or for a mutant single flower truss (sft) gene) or heterozygous or homozygous for both a mutant self pruning (sp) gene and a mutant single flower truss (sft) gene (double heterozygotes or double homozygotes).
In another embodiment, Solanaceae plants comprise a mutant self pruning (sp) gene and a mutant suppressor of spl (sspl) gene. Such Solanaceae plants are heterozygous or homozygous for mutant genes (e.g., for a mutant self pruning (sp) gene or for a mutant suppressor of spl (sspl) gene) or heterozygous or homozygous for both a mutant self pruning (sp) gene and a mutant suppressor of spl (sspl) gene (double heterozygotes or double homozygotes).
In yet another embodiment, Solanaceae plants comprise a mutant suppressor of spl (sspl) gene or a mutant single flower truss (sft) gene.

- 15 -DETAILED DESCRIPTION
Tomato yield, on both a per plant basis and in the context of tons per acre, depends partly on fruit size, but is mainly driven by the production of dozens of multi-flowered inflorescences and resulting fruit clusters that develop according to the "sympodial" growth habit. The defining feature of sympodial plants is that the shoot apical meristem (SAM) ends growth by differentiating into a terminal flower after producing a set number of leaves, and growth then renews from a specialized axillary (sympodial) meristem (SYM) that, in tomato, produces just three leaves before undergoing its own flowering transition and termination.
Indefinite reiteration of three-leaf sympodial flowering events results in an "indeterminate"
plant that continuously produces equally spaced inflorescences. The regular production of leaves between inflorescences is known as the "sympodial index" (SI).
Tomato breeding goals are multifaceted and shift according to the needs and desires of growers (e.g. improved pest resistances) and consumers (e.g. better quality), but one unwavering aim is to improve yield. Indeterminate cultivars are grown commercially to enable continuous market delivery of "round", "roma", "cocktail", "grape", and "cherry"
tomato types that are eaten fresh and command a premium price. Indeterminate tomatoes are primarily grown in greenhouses where successively ripening clusters are harvested by hand multiple times over an extended period, in some cases up to a year, to maximize yield on plants that must be pruned to one or two main shoots to enable efficient greenhouse growth and maintain fresh market quality. While the necessary pruning of indeterminate tomatoes facilitates agronomic practices that maximize quality, such as size, shape, and flavor, it also limits yield. In contrast, tomatoes grown for sauces, pastes, juices, or other processed can or jar products where fruit quality is less relevant, must be managed agronomically to produce maximum yields (per acre) through once-over mechanical harvests to be economically justified. Maximal yields for processing tomatoes are achieved by growing determinate sp mutants in the open field to their full potential, because sequential sympodial shoots transition to flowering progressively faster in sp plants, which results in a compact bush-like form where fruits ripen uniformly. Thus, sp varieties lend themselves to once-over mechanical harvesting and have therefore come to dominate the processing tomato industry, although determinate varieties have also been bred for fresh market production.

Indeterminate tomatoes are primarily grown in greenhouses where successively ripening clusters are harvested by hand multiple times over an extended period, in some cases up to a year, to maximize yield on plants that must be pruned to one or two main shoots to enable efficient greenhouse growth and maintain fresh market quality. While the necessary pruning of indeterminate tomatoes facilitates agronomic practices that maximize quality, such as size, shape, and flavor, it also limits yield. In contrast, tomatoes grown for sauces, pastes, juices, or other processed can or jar products where fruit quality is less relevant, must be managed agronomically to produce maximum yields (per acre) through once-over mechanical harvests to be economically justified. Maximal yields for processing tomatoes are achieved by growing determinate sp mutants in the open field to their full potential, because sequential sympodial shoots transition to flowering progressively faster in sp plants, which results in a compact bush-like form where fruits ripen uniformly. Thus, sp varieties lend themselves to once-over mechanical harvesting and have therefore come to dominate the processing tomato industry, although determinate varieties have also been bred for fresh market production. In a parallel to the physical pruning of indeterminate tomatoes, one drawback of sp-imposed determinate
- 16-growth is that inflorescence and fruit production is restricted, because of a genetic pruning that causes sympodial cycling to stop. Thus, maximizing inflorescence and fruit production while simultaneously minimizing shoot production for the tomato industry has remained a challenging goal.
One approach to increase inflorescence production and yield is to reduce SI to less than three. As described herein, chemically induced mutant populations of tomatoes in the self pruning (sp) background were screened for mutations that suppressed sp imposed growth determinacy, with the goal of producing indeterminate tomatoes with reduced SI. Three mutants were identified. The first mutant carried a novel mutation in the gene SINGLE
FLOWER TRUSS (SFT), the mutation referred to herein as sft-1906, which resulted in a weak allele. SFT is the tomato ortholog of the Arabidopsis thaliana gene FLOWERING
LOCUS T
(FT). The other two mutants were defective in a gene designated SUPPRESSOR OF
SP]
(SSP1), which encodes a protein partner of SFT. SSP1 is the tomato ortholog of the Arabidopsis thaliana gene FLOWERING LOCUS D (FD). These other two mutants are referred to herein as ssp-2129 or ssp-610. Remarkably, each homozygous sft and sspl mutant transforms determinate tomato plants into indeterminate tomato plants with a SI of less than three.
As described herein, data was generated in cherry and roma tomato types that demonstrate the utility of the new SFT and SSP1 mutations to serve as novel germplasm for breeding. Specifically, it was found that mixing and matching these mutations in various homozygous and heterozygous combinations resulted in a quantitative range of sympodial indices and novel determinate, semi-determinate, and indeterminate shoot architectures that have not been possible to achieve with existing breeding germplasm. Notably, it has been also found that these mutations increase the number of flowers per inflorescence.
The SSP1 and SFT mutations were introduced into the classic mutant self-pruning (sp) determinate background (sp-classic, coding sequence is SEQ ID NO: 8), which is a prerequisite genotype for generating indeterminate plants with a SI of less than 3. SP is the tomato ortholog of the Arabidopsis thaliana gene TERMINAL FLOWER] (TFL1). Data from the roma cultivar `M82' (which is homozygous for sp-classic) showed that homozygosity for ssp-2129 or ssp-610 in the sp-classic background results in semi-indeterminate plants with an average SI of 2. Data from a determinate variety of the cherry type 'Currant' tomato (S.

- 17 -pimpinellifolium) showed that homozygosity for sft-1906 or either of the sspl mutations created a SI of 2. Double heterozygotes of sft-1906 and ssp-2129 or ssp-610 in hybrids resulted in an average SI less than 2, illustrating that combining mutations in either homozygous or heterozygous states can lead to subtle quantitative manipulation of sympodial shoot architecture and yield potential. Finally, all three mutants increase the number of flowers per inflorescence, with sft-1906 exhibiting the strongest effect.

In a specific embodiment, genetically-altered Solanaceae plants, such as tomato plants designated herein as sft-1906 x M82 Fl, exhibited greater yield than the corresponding wild type tomato plants.

See Figure 8C and 8D, graphic representations of yield of fruit by heterozygous tomato plants described herein (e.g., double heterozygotes ssp2129 x sft1906 and ssp610 x sft1906, as well as the three heterozygotes indicated: sft1906 x M82F1; ssf610 x M82F1; ssp2129 x M82F1).
Also described herein are semi-determinate (SD) or semi-indeterminate (SID) Solanaceae plants, e.g., a tomato plant (Solanum lycopersicum), that comprise a mutant of SUPPRESSOR OF SP1 (SSP1). The SSP1 gene encodes a bZIP transcription factor that physically interacts with the florigen hormone, SFT, to induce the flowering transition and flower production. SSP1 has two domains, the bZIP domain and the SAP motif (Figure 1).
The bZIP domain contains a basic leucine zipper capable of interacting with DNA. The SAP
motif, "RTSTAPF" (SEQ ID NO: 11), is found in the C-terminus of SSP1 from amino acid position 211 to 217 in SEQ ID NO: 4. The SAP motif is similar to a conventional 14-3-3 recognition motif.

In D-type plants, the sympodial shoots produce progressively fewer leaves until the plant terminates growth in two successive inflorescences.
- 46 -In contrast, indeterminate (ID) tomato plants generate successive sympodial units (SYM) that produce three leaves each, and SYMs continue to reiterate to generate an ID
shoot. The M2 EMS mutation library described above was generated in an M82D background and self-crossed to produce approximately six thousand independent mutant tomato plants and many fertile mutants which contained mutations at unidentified locations which were carried over into the M3 inbred generation. These lines were screened in both the M2 and M3 generations for homozygous recessive mutant phenotypes that partially suppressed the determinate growth phenotype of the M82D background, resulting in a semi-determinate shoot architecture phenotype. In particular, flowering time, flower production per inflorescence, and shoot architecture were examined. Single lines were identified that contained at least one M3 plant with a semi-determinate phenotype.
Two M2 families, e2129 and e610, were identified that had a low frequency (less than or equal to ¨25%) of plants with an altered flowering time and shoot architecture resembling a semi-determinate phenotype. Figure 2 shows that homozygosity for the e2129 mutant (designated ssp-2129) in the sp-/- M82 mutant background suppressed sympodial shoot termination compared to the sp-/- mutant alone. Figure 2, left, depicts a sp-/-determinate plant where leaf number in each sympodial shoot gradually decreases, leading to shoot termination in two successive inflorescences. Figure 2, right, depicts an indeterminate wild-type plant where each sympodial unit produces three leaves and this process continues indefinitely.
Figure 2, center, depicts an ssp-2129; sp-/- double mutant with semi-determinate sympodial shoot development, such that each sympodial shoot unit now produces two leaves, instead of the typical three leaves produced in wild-type indeterminate tomato plants.
Figure 3 shows quantification of internode length among 4 inflorescences in determinate sp-/-mutants (M82D), semi-determinate ssp-2129; sp-/- double mutants and ssp-610; sp-/-double mutants (ssp-2129 and ssp-610, respectively), and wild-type plants (M82ID). The p-value was measured by a student's t-test against M82D and M82ID (P<0.01 for ssp-2129 and ssp-610, indicated by **).
Figure 4 shows quantification of leaf numbers produced by the primary shoot meristem (PSM) indicating flowering time and sympodial units in both sp-/- and ssp-2129;sp-/-3 0 backgrounds.

To identify the genetic mutation(s) resulting in the altered flowering time and shoot architecture in these two families, one family, e2129, was further analyzed using previously reported map-based cloning procedures (Lippman et al, PLoS Biology 2008). A
single M3 ssp-2129 mutant plant was crossed to a wild-type species, S. piminellifolium, with known polymorphisms throughout the genome (The Tomato Genome sequence, Nature, 2012). The Fl hybrid was then self-crossed to produce an F2 generation of progeny plants segregating for both the ssp-2129 mutation and the DNA polymorphisms between M82 and S.
pimpinellifolium. Approximately 200 F2 plants were scored for altered flowering time and semi-determinate shoot architecture phenotypes, reflecting homozygosity of the ssp-2129 mutation.
The homozygous mutant F2 plants (those with the altered flowering time and shoot architecture) were then genotyped with evenly spaced polymorphic DNA markers spanning all 12 tomato chromosomes using the bulk segregant mapping technique. DNA was isolated from at least 20 mutant plants (those with the altered flowering time and shoot architecture phenotype) and from 20 wild-type plants. DNA from the mutant plants was pooled to form pool 1 and DNA from the wild-type plants was pooled to form pool 2. A 10 centiMorgan (cM) scan was performed to identify M82 polymorphisms that were over-represented in pool 1 relative to pool 2, reflective of the origin of the ssp-2129 mutation in the M82 background.
Over-representation of polymorphisms in pool 1 was found within at 2Mb mapping interval between PCR markers 4029 and 4230, corresponding to 40M and 42M on chromosome 2, as shown in Figure 5.
To find the location of the mutation within this region, RNA was extracted from wild-type and mutant plants. This RNA was converted to cDNA and sequenced using Illumina sequencing. The sequencing reads were then mapped to the known gene annotations and only those within the 2 Mb region described above were analyzed. A large number of C to T
mutations were observed at a single location, position 647 according to SEQ ID
NO: 2 which corresponds to amino acid position 216 according to SEQ ID NO: 5, within the C-terminus of

- 48 -the tomato orthologue of the Arabidopsis FLOWERING LOCUS D (FD) gene. The tomato orthologue is referred herein as SUPPRESSOR OF SP1 (SSP1).
Following identification of the mutation present in the e2129 family, the e610 mutant, a confirmed allele in the SSP1 gene by complementation test with the ssp-2129 mutant as described below, was examined to see if the unknown mutation in that family also occurred in the SSP1 gene. Heterozygous plants with one copy of ssp-2129 and one copy of ssp-610 phenocopied the ssp-2129 homozygous mutant and the ssp-610 homozygous mutant plant, indicating that these two mutations were in the same gene. Following the complementation test, DNA was extracted from e610 mutant plants and Sanger sequencing was performed to determine if the SSP1 gene locus contained a mutation. A 'C' to 'T' mutation was identified in SSP1 at position 641 according to SEQ ID NO: 3 which corresponds to amino acid position 214 according to SEQ ID NO: 6.
Figure 5 summarizes the map-based cloning of the SSP1 gene discussed above.
Figure 5A shows the SSP1 map position on chromosome 2 localized to a 2.1M interval between markers inde14029 (4029x10k) and inde14230 (4230 x20k) was defined by bulk segragant analysis. An F2 mapping population segregating for the recessive sspl mutant was generated by self-pollinating an S. pimpinellifolium sp- x sspl sp- (cv. M82) Fl plant.
At least four insertion-deletion (indel) PCR markers were used for each of the 12 tomato chromosomes on a pool of DNA composed of 20 sspl mutant individuals compared to a pool of DNA
composed of 20 wild-type individuals. Deconvolution of the mutant pool revealed a recombination-defined internal of 40M-42.1M on chromosome 2. Figure 5B depicts Illumina RNA-sequencing (RNA-seq), which was performed on RNA isolated from reproductive meristems and used to identify and reconstruct DNA protein coding sequences from expressed genes in the mapping interval. RNA-seq reads revealed eight genes (positions indicated by arrows) expressed in meristems. Single nucleotide polymorphisms (SNP) were identified relative to the reference annotation for the eight expressed genes, which revealed a C-to-T DNA change in the coding sequence of 5o1yc02g083520 of the ssp-2129 mutant allele. Sequencing of the ssp-610 allele revealed a C-to-T change at a nearby location in the coding sequence of 5o1yc02g083520. Each mutation causes a missense amino acid changes in the conserved SAP motif of the closest tomato homolog of the Arabidopsis flowering gene FLOWERING LOCUS D (FD), encoding a bZIP transcription factor.
Following identification of the mutation present in the e2129 family, the e610 mutant, a confirmed allele in the SSP1 gene by complementation test with the ssp-2129 mutant as described below, was examined to see if the unknown mutation in that family also occurred in the SSP1 gene. Heterozygous plants with one copy of ssp-2129 and one copy of ssp-610 phenocopied the ssp-2129 homozygous mutant and the ssp-610 homozygous mutant plant, indicating that these two mutations were in the same gene. Following the complementation test, DNA was extracted from e610 mutant plants and Sanger sequencing was performed to determine if the SSP1 gene locus contained a mutation. A 'C' to 'T' mutation was identified in SSP1 at position 641 according to SEQ ID NO: 3 which corresponds to amino acid position 214 according to SEQ ID NO: 6.
Figure 5 summarizes the map-based cloning of the SSP1 gene discussed above.
Figure 5A shows the SSP1 map position on chromosome 2 localized to a 2.1M interval between markers inde14029 (4029x10k) and inde14230 (4230 x20k) was defined by bulk segragant analysis.

- 49 -A summary of the sequences of both the wild-type SSP1 gene and the two mutant alleles, ssp-2129 and ssp-610, is provided in Figures 6 and 7, which depict ClustalW analyses of the nucleotide and amino acid sequences, respectively. The nucleotide and amino acid sequences for wild-type SSP1, mutant ssp-2129, mutant ssp-610, wild-type SP, and mutant sp are also listed after Example 2. Mutations present in the nucleotide and amino acid sequences of each mutant nucleic acid or protein are indicated as underlined and bolded nucleotides or amino acids.
Example 2: Identifying mutant plants providing desirable plant traits such as brix, brix yield, red fruit yield, and total yield A mutant SINGLE FLOWER TRUSS (SFT) gene, sft-1906, was identified in tomato plants using the same techniques described above in Example 1. sft-1906 was determined to have a mutation of Valine to Methionine at position 132. A summary of the nucleotide and amino acid sequences of the wild-type SFT gene and the mutant allele, sft-1906, is provided in Figures 9 and 10, which depict ClustalW analyses of the nucleotide and amino acid sequences, respectively. The nucleotide and amino acid sequences for the wild-type SFT
gene and the mutant allele, sft-1906, are also listed below. Mutations present in the nucleotide and amino acid sequences of each mutant nucleic acid or protein are indicated as underlined and bolded nucleotides or amino acids.
Tomato plants carrying sft-1906 were crossed with tomato plants carrying ssp2120 or ssp610 and compared to plants having other genetic backgrounds (M82 (sp), ssp2129 x M82 Fl, ssp610 x M82 Fl, and sft1906 x M82 F1). It was found that all of the combined mutant tomato plants (ssp2129 x sft1906, ssp610 x sft1906, ssp2129 x M82 Fl, ssp610 x M82 Fl, and sft1906 x M82 Fl) had improved Brix Yield, Brix, Red Fruit Yield, and Total Yield compared to M82 plants (FIG. 8). Data on red and total fruit yield were generated from replicated field trials and Brix data was obtained using a refractometer (see below). Tomato plants doubly heterozygous for both an sspl mutation and a sft mutation had the highest improvement in Brix Yield, Brix, Red Fruit Yield, and Total Yield (FIG. 8).
Tomato plants were grown under wide (1 plant per m2) spacing using drip irrigation for field trials. When all plants have 80% or more red fruits, total fruits and total red fruits were measured by weight (kg) per plant. Ten red fruits collected randomly from each plant were used for

Brix-yield was calculated by the multiplied output of Brix and total fruit yield measured in g/m2. Each genotype in the experiments was represented by a minimum of 15 replicates in two locations (Riverhead, NewYork USA and Akko, Israel). All plants were transplanted in a completely randomized design.
