Many aspects regarding the role of lipopeptides (LPs) in bacterial interaction with plants are not clear yet. Of particular interest is LP family surfactin, immunogenic molecules involved induced systemic resistance (ISR) and colonization plant surfaces. We hypothesize that concentration surfactin produced by a strain correlates directly its ability to colonize persist on different surfaces, which conditions capacity trigger ISR. used two Bacillus velezensis strains (BBC023 BBC047), whose...
Abstract An understanding of biocontrol activities is important when developing microorganism‐based alternatives to conventional fungicides. From our bacterial collection, we selected two strains ( BBC 023 and 047) for their outstanding antagonistic capacity against fungal phytopathogens growth‐promoting abilities towards Arabidopsis thaliana . According physiological molecular characterizations, both were classified as Bacillus amyloliquefaciens tested Botrytis cinerea in vitro a tomato....
During the last decades, incorporation of beneficial microorganisms in agriculture crop management has become a common practice. Seed coating these still faces technical issues, which limit its implementation conventional agriculture. An adaption to widely established agricultural practices, e.g. fertigation, could help overcome issues. Here, using Bacillus velezensis strain BBC047, we show influence phenological stages on efficiency and success microbial inoculation under conditions. In...
Abstract BACKGROUND Consumption of bell peppers is recommended because their bioactive compound content and positive effects on health. Growth‐promoting rhizobacteria are popular ability to promote plant growth by improving the fixation nutrients or inducing a systemic response. Green pepper ( Capsicum annum ) roots were inoculated with an autochthonous strain Bacillus amyloliquefaciens , at different stages development: T1, inoculation in seedbed before transplant; T2, after T3, seedbed,...
Tomato (Solanum lycopersicum L.) is an important crop in the Azapa Valley (18°35' S, 69°30' W) northern Chile, with approximately 600 ha of fresh tomatoes under greenhouses. Cultivars resistant to Fusarium oxysporum f. sp. lycopersici (FOL) races 1 and 2 are mainly used. However, 2012 2013, wilt incidence was 3%. Symptoms appeared unilaterally consisted yellowing, leaf wilting lower leaves, dark brown vascular discoloration, plant death. The aim this study determine causal agent tomato seven...
Induced systemic resistance (ISR) is one of the most studied mechanisms plant−microbe interaction and considered a very promising alternative for integrated pest management programs. In our study, we explored plant defense response induced by Bacillus velezensis BBC047 in relation to its application before or after Botrytis cinerea infection tomato plants. The inoculation did not considerably alter gene expression tissues, whereas with B. BBC047-primed plants LRR NBS-LRR receptors, which are...
