Description

Upland cotton plant height regulating gene GhGA20ox6 and its use

Technical Field

The invention relates to the technical field of genetic engineering, in particular to a upland cotton plant height regulating gene GhGA20ox6 and application thereof.

Background

Gibberellin (Gibberellin, GA) asOne of six plant hormones, namely a tetracyclic diterpenoid plant hormone plays an important role in each growth and development stage of plants, and plays an important role in seed germination, root cap elongation, flowering and fruiting, stem elongation, leaf growth and development and the like. In higher plants, various enzymes are involved in the biosynthesis and metabolism of gibberellin through a multi-step enzymatic reaction, and the expression of these enzyme genes is effective in regulating the anabolic rate of gibberellin. There are many enzymes involved in gibberellin anabolism, GA2-oxidase (GA2-oxidase) is a key enzyme in the degradation of GA in plants, and GA2ox can decompose and inactivate GAs active in plants and their precursors and intermediates, thereby maintaining the homeostasis between the active GAs in plants. GA3-oxidase (GA3-oxidase) and GA20-oxidase (GA20-oxidase) as key enzymes in the last step of plant gibberellin anabolic pathway to catalyze GA₁₂And GA₅₃Conversion to active GA₁And GA₄In addition, GA3ox and GA20ox in turn regulate negative feedback of active GAs within the receptor. The plant gibberellin oxidase gene family belongs to the 2OG-Fe (II) oxidase subfamily and can be coded by a polygene family. To date, the gibberellin synthesis and metabolic pathways of the model plant Arabidopsis thaliana have been well studied, and gibberellin-related genes have also been cloned and identified. Researches show that the 'green revolution' of the current main crops has close relationship with gibberellin. In plants, gibberellin participates in the regulation of the growth and development of plants, the advantages of promoting stem elongation and plant height increase are that, for example, in rice, through cloning and gene silencing of GA20ox related genes, the genes are found to influence the stem length of the rice, and then the rice is caused to have a dwarf phenotype, and researches of Mauriat et al find that the GA20ox related genes influence the stem elongation of populus tremuloides, and GA20ox related gene expression is enhanced on populus tremuloides seedlings, so that the gibberellin promotes the synthesis of active gibberellin in seedlings.

GhGA20ox6 is located on chromosome 9 of subgroup D, and has an open reading frame of 1155bp, an amino acid sequence of 384 nucleotides in length (SEQ ID NO: 14), 2 introns and 3 exons. The relative molecular mass of the GhGA20ox6 protein sequence is predicted to be 42.32kDa by using ExPASy online software, and the isoelectric point is 6.37. The DIOX _ N domain is located at amino acid sequences 63-172, and the 2OG-Fe (II) oxidase domain is located at amino acid sequence 228-323. The amino acid sequence analysis of the proteins corresponding to the 13 candidate genes shows that the proteins corresponding to the 13 candidate genes including the GhGA20ox6 all have a common conserved protein sequence: the highly conserved motif LPWKET associated with substrate binding, the conserved sequence NYPXCQKP associated with binding 2-ketoglutarate, all have Fe²⁺A binding site.

2.2 spatial expression Pattern analysis of the GhGA20ox6 Gene

To study the tissue expression characteristics of GhGA20ox6, the expression level of the GhGA20ox6 in 9 tissues of TM-1 upland cotton material 15DPA fiber, ovule, flower, sepal, terminal bud, stem, leaf, pistil and stamen was analyzed by qRT-PCR method. The results show that: in these 9 tissues, GhGA20ox6 was predominantly expressed in the stem, whereas the expression level was lower in both ovule and flower tissues (fig. 1). It is further speculated that GhGA20ox6 functions during the growth and development of the stem.

2.3 subcellular localization analysis of GhGA20ox6 protein

The protein sequence of GhGA20ox6 is shown in WoLF PSORT (https://wolfpsort.hgc.jp/) Subcellular localization prediction was performed on online software, and results showed localization at cell membranes. To verify whether the GhGA20ox6 protein was localized on the cell membrane, leaf cells of Nicotiana benthamiana were transiently expressed with GhGA20ox6 (FIG. 2). The results showed that there was a bright green distribution in the cell membrane, indicating that there was a large amount of green fluorescence signal in the cell membrane, consistent with the predicted results, indicating that the GhGA20ox6 protein is a membrane localization protein.

2.4 phenotypic Observation and expression level analysis of the GhGA20ox6 Gene after silencing

Cotton plants of the positive control pCLCrVA-PDS exhibited the albino phenotype, and cotton plants of pCLCrVA-GhGA20ox6 exhibited different degrees of shortening between the internodes of the stem compared to the control group (FIG. 3), and the plant height data were plotted as a histogram (FIG. 4). The results show that the height of the positive strain subjected to virus-induced gene silencing is obviously reduced, the length of the first internode and the length of the third internode are slightly shortened, and the length of the second internode, the length of the fourth internode and the length of the sixth internode are obviously shortened, which indicates that GhGA20ox6 silencing can cause dwarfing of the strain type. The level of the expression level of the GhGA20ox6 between the six sections was determined, and the real-time fluorescence quantitative results showed that the expression level of the GhGA20ox6 between the first section and the third section was not significantly different from that of the inoculated no-load control group, and the expression level of the GhGA20ox6 between the second section, the fourth section, the fifth section and the sixth section was significantly different from that of the control group (FIG. 5). Silencing of the GhGA20ox6 gene is presumed to result in shortening between different nodes of the stem.

2.5 functional verification of GhGA20ox6 Gene in Arabidopsis thaliana

Under long-day conditions, wild-type and transgenic Arabidopsis thaliana were grown simultaneously and growth was observed (FIG. 6). The results show that the wild type arabidopsis started bolting 22 days after seedling transplantation, the average bolting time was 25 days, the transgenic arabidopsis started bolting 18 days after seedling transplantation, the average bolting time was 20 days, and the bolting time was significantly earlier than that of the control wild type.

3. Discussion of the related Art

The gibberellin 20 oxidase family plays an important role in the growth and development of plants and environmental adaptation, and is an important key enzyme for synthesizing active gibberellin in plants.

The invention clones 1 gibberellin oxidase gene GhGA20ox6 from TM-1 land cotton material, and through amino acid multiple sequence comparison, finds that the GhGA20ox6 protein sequence has highly conserved motif LPWKET combined with substrate, conserved sequence NYXYXCQKP related to combined 2-ketoglutarate, and the GhGA20ox6 gene has obvious difference in expression level in different TM-1 tissues and higher expression level in stem tissues. The GhGA20ox6 gene is considered to be involved in the growth and development of cotton stems, and influences the plant height trait.

At present, the plant height is basically controlled by castration and topping in agriculture, so that on one hand, labor force is increased, and the working time is prolonged. By using VIGS experiments and transgenic overexpression experiments, the research on the expression level of the GhGA20ox6 gene in plants on a molecular level proves that the GhGA20ox6 gene plays a role in regulating and controlling the plant height traits of the plants.

4. Conclusion

The invention clones GhGA20ox6 gene from stem of upland cotton material TM-1 by T-A cloning method, and the GhGA20ox6 gene has 2OG-Fe (II) oxidative gene and DIOX _ N structural domain by amino acid sequence analysis. The cDNA of the GhGA20ox6 gene is 1155bp, and codes 384 amino acids. Subcellular localization prediction and experimental results show that both localize to the cell membrane. The expression level of TM-1 shows that the GhGA20ox6 gene has obvious tissue specificity and the highest expression level in stem. The VIGS experiment results show that the silencing of the GhGA20ox6 gene in cotton enables different stem nodes of the cotton to have dwarfing phenotypes of different degrees compared with a control group, and the expression level of the GhGA20ox6 gene between different nodes is reduced in different degrees. The results of heterologous overexpression of the transgenic arabidopsis show that compared with the wild type, the transgenic arabidopsis has the advantages of increased rosette leaf number, advanced bolting time and obvious increase of plant height, and the GhGA20ox6 gene plays an important role in plant height and shape.
