“…The data corroborate with the results found by Akram, Anjum, and Ali (2015), who evaluated the application of B. subtilis gainst tomato fusarium wilt and determined the concentration of enzymes such as phenylalanine ammonia lyase, polyphenoloxidase and peroxidase, with a significant increase in PPO and POD activities.…”

The objective of this work was to evaluate the effectiveness of seed treatment with fresh suspensions and powder formulations with Bacillus methylotrophicus to promote plant growth and induction of resistance against fusarium wilt (Fusarium oxysporum f. sp. lycopersici) in tomato plants under greenhouse conditions, verifying the occurrence of morphological and biochemical changes in the evaluated plants. Powder formulations based on Cassava (Manihot esculenta), Arrowroot (Maranta arundinacea) and sodium alginate containing Bacillus, in addition to the commercial product Quartz®, were used to microbiolize the tomato seeds of the cultivar Santa Cruz. The formulations promoted plant growth, with a seedling vigor index greater than 50% for all treatments containing B. mthylotrophicus, in addition to a significant increase in total dry matter. The treatments induced systemic resistance, controlling the fusarium wilt with a 75% reduction of the disease and activation of enzymes such as peroxidase and polyphenoloxidase, only β-1,3-glucanase presented less activity than controls (treatments without B. mthylotrophicus). Thus, the use of formulations containing Bacillus are efficient in promoting plant growth of tomato plants and in inducing resistance to the control of fusarium wilt.

“…Searching for new active endophytic bacteria may be considered as a promising way of controlling plant diseases using environmentally safe alternatives. These bacteria may inhibit pathogen growth through the production of antibiotics (Bacon and Hinton 2011), cell wall-degrading enzymes (Berg et al 2005), competition for nutrients and minerals (Wang et al 2013) and/or induced resistance (Akram et al 2015). As is the case for plant growth-promoting bacteria, endophytic bacteria can enhance plant growth by activating a number of similar mechanisms, including indole-3-acetic acid and siderophore production and phosphate solubilization ability (Sgroy et al 2009).…”

Seven culturable bacterial isolates, obtained from the internal stem tissues of Solanum elaeagnifolium and successfully colonizing the internal stem tissues of tomato cv. Rio Grande, were screened for their in vivo antifungal activity against Fusarium oxysporum f.sp. lycopersici (FOL) and their growth‐promoting potential on tomato plants. SV101 and SV104 isolates, assessed on pathogen‐challenged tomato plants led to a significant decrease (77–83%) in Fusarium wilt severity and vascular browning extent (76%), as compared to the inoculated and untreated control. Isolates enhanced growth parameters on pathogen‐challenged and unchallenged tomato plants. SV104 and SV101 isolates were most effective in suppressing disease and enhancing plant growth. These two isolates were identified as Bacillus sp. str. SV101 () and B. tequilensis str. SV104 (). They displayed antifungal activity against FOL; pathogen growth was inhibited by 64% and an inhibition zone (11.50 and 19.75 mm) against FOL could be formed using whole cell suspensions. SV101 and SV104 extracellular metabolites also inhibited FOL growth by 20 and 55%, respectively, as compared to control. B. tequilensis str. SV104 was shown to produce protease, chitinase, pectinase, IAA and siderophores. Bacillus sp. str. SV101 displayed pectinase activity and was found to be an IAA‐producing and phosphate‐solubilizing agent. To our knowledge, this is the first study reporting on S. elaeagnifolium use as a potential source of potent biocontrol and plant growth‐promoting agents.

Background: Bacillus subtilis strains have been widely studied for their innumerous benefits in agriculture, including viticulture. Providing numerous assets, B. subtilis spp. are described as promising plant-protectors against many pathogens and as influencers to adaptations in a changing environment. This study reports the draft genome sequence of the beneficial Bacillus subtilis PTA-271, isolated from the rhizospheric soil of healthy Vitis vinifera cv. Chardonnay at Champagne Region in France, attempting to draw outlines of its full biocontrol capacity. Results: The PTA-271 genome has a size of 4,001,755 bp, with 43.78% of G + C content and 3,945 protein coding genes. The draft genome of PTA-271 highlights (1) a functional swarming motility system hypothesizing a colonizing capacity and a strong interacting capacity, (2) strong survival capacities and (3) a set of genes encoding for bioactive substances. Bioactive compounds are known both to (i) stimulate plant growth or defenses such as hormones and elicitors, (ii) influence beneficial microbiota, and (ii) counteract pathogen aggressiveness such as effectors and many kinds of detoxifying enzymes. Conclusions: The plurality of the encoded biomolecules by Bacillus subtilis PTA-271 genome appears as strengths for PTA-271 biocontrol potential towards plants, offering a big potential against a broad spectrum of pathogens despite environmental constraints.
