Description

BACILLUS AMYLOLIQUEFACIENS FCC1256 COMPOSITIONS AND METHODS OF

CONTROLLING PLANT PATHOGENS

TECHNICAL FIELD

The presently disclosed subject matter relates to compositions comprising an isolated Bacillus amyloliquefaciens FCC1256 strain for application to plants or the soil surrounding plants to treat plant diseases caused by plant pathogens.

BACKGROUND

Fungal plant pathogens (phytopathogens), including but not limited to Botrytis spp., Fusarium spp., Rhizoctonia spp. are one type of plant pest that can cause severe economic losses in the agricultural and horticultural industries. Chemical agents can be used to control fungal phytopathogens, but the use of chemical agents suffers from disadvantages including high cost, lack of efficacy, emergence of resistant strains of the fungi, and undesirable environmental impacts. In addition, such chemical treatments tend to be indiscriminant and may adversely affect beneficial bacteria, fungi, and arthropods in addition to the plant pathogen at which the treatments are targeted. A second type of plant pest are bacterial plant pathogens, including but not limited to Erwinia spp., Xanthomonas spp., and Pseudomonas spp. that cause severe economic losses in the agricultural and horticultural industries. Similar to pathogenic fungi, the use of chemical agents to treat these bacterial pathogens suffers from disadvantages. Thus, microorganisms that can be applied as biopesticides to control pathogenic fungi and bacteria in plants are desirable and in high demand to improve agricultural sustainability.

Some members of the species Bacillus have been reported as biocontrol strains, and some have been applied in commercial products. For example, strains currently being used in commercial biocontrol products include: Bacillus velezensis QST713, used as the active ingredient of Serenade^®, produced by Bayer Crop Science, and Bacillus amyloliquefaciens D747, used as the active ingredient in Double Nickel produced by Certis. In addition, Bacillus strains currently being used in commercial biostimulant products include: Bacillus velezensis FZB42 used as the active ingredient in Rhizo Vital^® 42, produced by ABiTEP GmbH.

Moreover, WO 2016/109396 Al discloses Bacillus amyloliquefaciens RTI472 for use in benefiting plant growth and for treating plant diseases like fungal and bacterial infections.

Further, WO 2016/109395 Al discloses Bacillus amyloliquefaciens RTI301 for use in benefitting plant growth and for treating plant diseases like fungal and bacterial infections.

Also, WO 2015/023662 Al discloses, i.a., a Bacillus amyloliquefaciens strain for inhibiting the growth and/or activity of fungal plant pathogens.

However, despite the availability of certain biological pesticides, there is a need in the art to improve specificity against the target diseases and their respective causal pathogens. Further, there is a need to improve efficacy and potency of biological pesticides which may be impacted by various biotic and abiotic factors. The present invention addresses the need in the art by providing novel microbial compositions and methods for their use to control the growth of plant pathogens and thereby alleviate or prevent plant diseases.

In some embodiments, the concentrate comprises iturin and fengycin in a relative weight ratio of in the range of from 1.3: 1.0 to 3.0: 1.0, such as from 1.5: 1.0 to 2.8: 1.0, including all measurements within such ranges.

EXAMPLES

The following Examples have been included to provide guidance to one of ordinary skill in the art for practicing representative embodiments of the presently disclosed subject matter. Considering the present invention and the general level of skill in the art, those of skill can appreciate that the following Examples are intended to be exemplary only and that numerous changes, modifications, and alterations can be employed without departing from the scope of the presently disclosed subject matter.

Methods

Identification of iturin. fengycin and surfactin

Samples were analyzed by reverse phase LC-DAD using a Cl 8 column with a screening gradient that allowed the simultaneous detection of all three lipopeptide families. The mobile phases consisted of water and acetonitrile premixed with 0.1% formic acid. Compounds were identified based on their retention times and ETV spectra compared with authentic standards.

Determination of colony-forming units (CFU)

The CFET of a sample (expressed as CFU/mL for liquid samples and as CFET/g for solid samples) can be determined according to BS EN 15784:2009 (“ Animal feeding stuffs. Isolation and enumeration of presumptive Bacillus sppJ).

Example 1

Identification of a Bacterial Isolate as a Bacillus amyloliquefaciens through Sequence Analysis A plant associated bacterial strain, designated herein as Bacillus amyloliquefaciens FCC1256, was isolated from strawberry plant soil from Autryville, NC, USA. The strain of Bacillus amyloliquefaciens FCC1256 was deposited on 12 May 2015 under the terms of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure at the American Type Culture Collection (ATCC) in Manassas, Virginia, USA and bears the Patent Accession No. PTA-122162.

Initially, the whole genome sequence data of Bacillus amyloliquefaciens FCC1256 was mined to identify core phenotypic marker genes that are routinely used for phylogenetic assignment. Genes that are chosen for this analysis are both single copy, there is only one copy of the gene in the genome, and has a core housekeeping function for the cell. The six genes that were chosen from the RAST annotation file were the DNA-directed RNA polymerase beta subunit ( rpoB ), DNA repair recombinase A ( recA 2), DNA mismatch repair protein S ( mutS ), glycerol uptake facilitator protein ( glpF ), DNA gyrase subunit B (gyrB ) and DNA chaperone K ( dnaK ). For each of the selected genes, representative strains of genomes for the genus Bacillus {Bacillus subtilis cluster and Bacillus cereus cluster) were used for comparison. To that end, FCC1256 was identified as a new strain of Bacillus

amyloliquefaciens through sequence analysis of highly conserved 16S rRNA and rpoB genes.

Also included for each gene is an outgroup sequence. These outgroup sequences are mined from genomes of phylogenetically divergent bacteria to provide an indication of the robustness of the phylogenetic calculations.

Each reference genome was first downloaded from NCBI and annotated in the RAST annotation pipeline. Each of the annotation tables generated was subsequently searched to identify each of the selected housekeeping genes and the sequences for each gene was then copied and pasted into a new nucleotide alignment in the MEGA 5.2 software program. Once each gene sequence has been loaded into the alignment all specific gene sequences were aligned using the ClustalW alignment algorithm. After each group of genes were aligned the sequences were then trimmed to ensure that each sequence had the same number of nucleotides. Following the trimming step, the aligned sequences were then used to create phylogenetic trees.

Each phylogenetic tree was replicated 1000 times to assess the robustness of the phylogenetic grouping. For each tree FCC1256 aligns and trees with other Bacillus amyloliquefaciens strains like DSM7, RTI301 and RTI472. These results indicate with high confidence that FCC1256 is indeed a Bacillus amyloliquefaciens. The antagonistic effect of FCC1256 against a number of pathogens was also determined. Table 1 below provides a summary of the results.

+++ very strong activity, ++ strong activity, + activity, +- weak activity, - no activity observed

In addition, experiments were performed to determine the antagonistic activities of Bacillus amyloliquefaciens FCC1256 in vitro and in various plants under varying conditions. The experimental results are provided in Examples 3, 5, 6 and 7 below.

The experiments i.a. show the ability of Bacillus amyloliquefaciens FCC1256 to confer protection against or control plant pathogenic infection as compared to commercially available Serenade^® (Bayer CropScience, Inc.) that contains as an active ingredient Bacillus velezensis Q S T713.

Example 2

Fermentation of Bacillus amyloliquefaciens FCC1256

Bacillus amyloliquefaciens FCC1256 was first streaked out from a glycerol stock onto a solid 869 media, which contained (in 1 L): 10 g tryptone, 5 g yeast extract, 1 g D-glucose, 0.3 g CaCl₂, and 15 g powdered agar. After incubating at 30°C overnight, a single colony was picked up to inoculate a 250-mL shake flask with 50 mL of media containing (in 1 L): 10 g peptone, 6 g yeast extract, 2 g KC1, and 0.1 g MgSCri^FhO. After autoclaving, the following solutions were added to the medium: 5 mL of 20% glucose, 1 mL of 1M CaCl₂, 1 mL of 0.1 M MnCl₂, and 10 pL of 0.1 M FeS0_4. The shake flask was incubated in a shaking incubator at 30°C and 200 rpm until the OD600 reached 1.0. The cell pellets were collected for the inoculation of fermenters (working volume 1.5 L, Bioflo 320, Eppendorf). The fermentation was made at 30°C, agitation speed was 800 rpm, and the air supply rate was 2 L/min. Samples were taken during the fermentation to monitor cell growth, cell sporulation, and metabolite concentrations. After 168 hours of fermentation, most of the Bacillus

amyloliquefaciens FCC1256 cells had sporulated, and the whole culture mixture was harvested.

Bacillus amyloliquefaciens FCC1256 and reference strain QST713 (a Bacillus velezensis strain obtained from a commercial Serenade^® product) were fermented in the above-mentioned culture medium. Using the OD600 measurement, the biomass levels during fermentation were measured. A comparison of the metabolite profiles for the Bacillus amyloliquefaciens FCC1256 strain and QST713 showed that FCC1256 produced iturin at a significantly higher rate than QST713 under the same conditions.

Further evaluation of the metabolite concentrates revealed that FCC1256 had an iturin :fengycin: surf actin weight ratio at about 3.3 : 1.4: 1, potentially contributing to the antagonistic activities of the strain against plant pathogens.

Following, a single colony was transferred in medium (growth medium FLO, 914.3 mL; NH4NO3, 8 g; Na₂HP0₄, 7.15 g; KH2PO4, 6.8 g; yeast extract 0.5 g; adjusted to 7.5 with 4 mL 4 M KOH; 45 mL of the growth medium were transferred to a 250-mL baffled flasks and autoclaved at 12LC for 15 min. After autoclaving the following solutions were added in each flask: 0.1 M CaCh 5 pL, 0.1M MnCL 5 pL, 0.1M FeSCL 35 pL, 0.1M ZnCl₂ 5 pL, 1M MgSCL 100 pL, glucose 50 % sol (final cone. 40 g/L) 4 mL) and incubated for 168 h at 30 ^°C and under continuous agitation (220 rpm). The strains were grown in 250-mL baffled flasks with GL 45 thread (Duran^®, Germany) and 50 mL final working volume.

In total, 14 foliar plant pathogens (12 fungi and 2 bacteria) were used during this study. Specifications of the pathogens, the growth conditions and media used are shown in Table 2. All foliar pathogens used for this experiment were tested in Potato Dextrose Agar (PDA) solid medium except Pseudomonas syringae and Xanthomonas axonopodis which were tested in Trypticase soy agar (TSA) solid medium. The incubation time of each pathogen before treatment varied from 3 to 5 days. In case of Pseudomonas syringae and Xanthomonas axonopodis where lawn plates are used for testing, an overnight culture on 869 media was prepared while Septoria tritici was cultured on Potato Dextrose Broth for 5 days before lawn preparation.

The activity was assessed by the application of 20 pL of cells. All applications were conducted in triplicates for all pathogens using the fermented material non-filtered. Rating timings for fungal pathogens vary by species. Timing should correspond to the colony edge reaching a radius of approximately 25 mm on the control spot plates. For the assessment, a semi-quantitative method was used, cf. the following 4-scale system (0-3) where: 0: no antimicrobial effect seen; 1: slight effect caused but no obvious clearing zone; 2: a clearing zone is obvious; 3: large clearing zone is present. The results are shown in Table 2.

Table 3. Phenotypic Assays: phytohormone production, acetoin and indole acetic acid (IAA), and nutrient cycling of Bacillus amyloliquefaciens FCC1256.

+++ very strong, ++ strong, + some, +- weak, - none observed

Acetoin Test. 20 pL of a starter culture in media was transferred to 1 mL Methyl Red Voges Proskauer media (Sigma Aldrich 39484). Cultures were incubated for 2 days at 30°C 200 rpm. 0.5 mL culture was mixed with 0.3 mL 5% alpha-naphthol (Sigma Aldrich N1000) followed by 0.1 mL 40% KOH. Samples were interpreted after 30 min. of incubation.

Development of a red color indicated acetoin production. Non-inoculated media was used as a negative control (Sokol et ah, 1979, Journal of Clinical Microbiology 9: 538-540).

Chitinase activity. 10% wet weight colloidal chitin was added to modified PVK agar medium (10 g glucose, 0.2 g potassium chloride, 0.5 g ammonium sulfate, 0.2 g sodium chloride, 0.1 g magnesium sulfate heptahydrate, 0.5 g yeast extract, 2 mg manganese sulfate, 2 mg iron sulfate and 15 g agar per liter, pH 7, autoclaved). Bacteria were plated on these chitin plates; zones of clearing indicated chitinase activity (N. K. S. Murthy & Bleakley,

2012.“Simplified Method of Preparing Colloidal Chitin Used for Screening of Chitinase Producing Microorganisms”. The Internet Journal of Microbiology 10(2)).

Indole-3-Acetic Acid. 20 pL of a starter culture in media was transferred to 1 mL 1/10 869 media supplemented with 0.5 g/L tryptophan (Sigma Aldrich T0254). Cultures were incubated for 4-5 days in the dark at 30°C, 200 rpm. Samples were centrifuged and 0.1 mL supernatant was mixed with 0.2 mL Salkowski’s Reagent (35% perchloric acid, 10 mM FeCh). After incubating for 30 min. in the dark, samples resulting in pink color were recorded positive for IAA synthesis. Dilutions of IAA (Sigma Aldrich 15148) were used as a positive comparison; non-inoculated media was used as negative control (Taghavi, et ah, 2009, Applied and Environmental Microbiology 75: 748-757).

Protease Activity. Bacteria were plated on 869 media supplemented with 10% milk. Clearing zones indicated the ability to break down proteins suggesting protease activity (Sokol et ah, 1979, Journal of Clinical Microbiology 9: 538-540).

Phosphate Solubilizing Test. Bacteria were plated on Pikovskaya (PVK) agar medium consisting of 10 g glucose, 5 g calcium triphosphate, 0.2 g potassium chloride, 0.5 g ammonium sulfate, 0.2 g sodium chloride, 0.1 g magnesium sulfate heptahydrate, 0.5 g yeast extract, 2 mg manganese sulfate, 2 mg iron sulfate and 15 g agar per liter, pH 7, autoclaved. Zones of clearing were indicative of phosphate solubilizing bacteria (Sharma et al., 2011, Journal of Microbiology and Biotechnology Research 1 : 90-95).

Example 7

Detached Pepper Leaf Disk assay comparing the activity of Bacillus amyloliquefaciens FCC1256 to untreated controls as well as to the commercial product Serenade^® Optimum.

Pepper {Piper capsicum ) plants were grown in greenhouse at 20-25 °C with 14-16 hours daylight for 6-7 weeks. From each plant, four fully expanded leaves from the middle part were harvested and put in petri dishes with moist filter paper. Leaves were sprayed with water (untreated control) or suspension of Serenade^® Optimum (positive control) or FCC1256 fermentates (two different batches). Then lids were put on thee petri dishes and placed for incubation in a growth chamber set at approx the same growth conditions as the greenhouse.

The following day the leaves were inoculated by spraying with a spore suspension of Botrytis cinerea , adjusted to 500,000 spores/mL. Then the petri dishes were put back in the growth chamber and evaluated after 4 days, 6 days and 9 days to follow the progression of the disease. The results are shown in Figure 1. Column 1 shows the Serenade^® Optimum reference (application equivalent of 2.8 kg/ha); Column 2 shows the untreated inoculated control; Column 3 shows the untreated uninoculated control, Columns 4 and 5 show Bacillus amyloliquefaciens FCC1256 of two different fermentation batches. Rows 1 and 2 show results 4 days post inoculation. Rows 5 and 6 show the same leaves but 6 days post inoculation, and rows 3 and 4 show again the same leaves but 9 days post inoculation.

By visual inspection it is clearly see that the leaves of the untreated inoculated control (column 2) were highly damaged even after 4 days, and that the leaves of the untreated uninoculated control (column 3) remained fresh throughout the 9 days experiment. The Serenade^® Optimum reference showed some pathogen control after 3 days, by the leaves were highly damaged after 6 and 9 days. On the other hand, the FCC1256 fermentates showed very good pathogen control after 4 and 6 days, and acceptable control after 9 days.

Whole plant Pepper assay comparing the antifungal activity of Bacillus amylolicwefaciens FCC1256 against Pepper Grey Mold ( Botrytis cinerea ) to untreated controls as well as to other Bacillus amyloliquefaciens strains

Four different Bacillus amyloliquefaciens strains, FCC1256, DSM7, RTI472 and RTI301, were fermented under similar conditions (cf. Example 2), except that the

fermentations were conducted in a smaller scale using 500 mL shake flasks with 60 mL culture. The growing temperature was 28 °C, the agitation was 200 rpm and the incubation time was 144 hours. The fermentations each provided a spore concentration in the order of lxlO⁷ CFU/mL.

Pepper plants {Piper capsicum variety Lamuyo Fl) were produced in 7x7x7 cm plastic pots, using Agrofmo 201 soil substrate. They were aged of 6 weeks at the time of the test. Watering of the plants was provided every two days using fertilization of

N:P:K=20:20:20 at 160 ppm. Six replicates were used per tested modality, each replicate consisting in 1 plant (1 pot).

Each plant was treated inside a laboratory sprayer using a 3 -nozzle boom at an estimated volume of 1000 L/ha. Each of the four different Bacillus amyloliquefaciens strains, FCC1256, DSM7, RTI472 and RTI301, were used at a dose of 20 mL of fermentation broth diluted in 100 mL of demineralized water and was mixed with 0.2 % vol/vol of an adjuvant mixture. The fermentation medium with the 0.2 % vol/vol adjuvant mixture and without Bacillus strain was also evaluated as a reference.

After application, plants were stored in growth chamber at 20°C, 70% RH and 16 hours photo-period. Inoculation was carried out 24 hours after fungicide application, by manually spraying inoculum of Botrytis cinerea on treated plants up to run-off. Inoculum concentration was 50,000 spores/mL inside PDB medium (strain of Botrytis cinerea FF248). After inoculation, plants were stored for 48 hours in a dew chamber at 20°C (no light) to favor infection. Plants were then place in a growth chamber at 20°C, 70% RH and 16 hours photo-period, up to disease rating.

Disease assessment was done three days after inoculation, by evaluating % severity on four fully developed leaves per plant. The averaged % severity per pot was then calculated (reported in Table 6), and the efficacy of the tested strains was calculated using Abott formula:

% control A = 100 * ((% severity A - % severity untreated) / % severity untreated) Table 6. Results of Bacillus amyloliquefaciens FCC1256 control of Pepper Grey Mold ( Botrytis cinerea) as compared with Bacillus amyloliquefaciens strains RTI301, DSM7 and
