Bacillus velezensis is considered as model species for plant-associated bacilli providing benefits to its host such protection against phytopathogens. This mainly due the potential secrete a wide range of secondary metabolites with specific and complementary bioactivities. metabolite arsenal has been quite well defined genetically chemically but much remains be explored regarding how it expressed under natural conditions notably can modulated upon interspecies interactions in competitive...
Abstract The linear chromosome of the bacterium Streptomyces exhibits a remarkable genetic organization with grossly central conserved region flanked by variable chromosomal arms. terminal diversity co-locates an intense DNA plasticity including occurrence large deletions associated to circularization and arm exchange. These observations prompted us assess role double strand break (DSB) repair in following. For that purpose, DSBs were induced along using meganuclease I- Sce I. DSB was...
Plant-associated Bacillus velezensis and Pseudomonas spp. represent excellent model species as strong producers of bioactive metabolites involved in phytopathogen inhibition the elicitation plant immunity. However, ecological role these during microbial interspecies interactions way their expression may be modulated under naturally competitive soil conditions has been poorly investigated.
Bacillus velezensis isolates are among the most promising plant-associated beneficial bacteria used as biocontrol agents. However, various aspects of chemical communication between plant and these beneficials, determining root colonization ability, remain poorly described. Here we investigated molecular basis such interkingdom interaction occurring upon contact its host via sensing pectin backbone homogalacturonan (HG). We showed that B. stimulates key developmental traits a dynamic process...
The region of the third chromosome (84D-F) Drosophila melanogaster that contains doublesex (dsx) locus has been cytogenetically analyzed. Twenty nine newly induced, and 42 preexisting rearrangements broken in dsx regions flanking have cytologically genetically characterized. These studies established is salivary band 84E1-2. In addition, these observations provide strong evidence functions only to regulate sexual differentiation does not encode a vital function. To obtain new alleles at...
Bacillus velezensis is considered as a model species belonging to the so-called subtilis complex that evolved typically dwell in soil rhizosphere niche and establish an intimate association with plant roots. This bacterium provides protection its natural host against diseases represents one of most promising biocontrol agents. However, molecular basis cross talk this establishes has been poorly investigated. We show here these plant-associated bacteria have polymer-sensing system perceive...
Non homologous end-joining (NHEJ) is a double strand break (DSB) repair pathway which does not require any template and can ligate two DNA ends together. The basic bacterial NHEJ machinery involves partners: the Ku protein, end binding protein for DSB recognition multifunctional LigD composed ligase, nuclease polymerase domain, processing ligation of broken ends. In silico analyses performed in 38 sequenced genomes Streptomyces species revealed existence large panel NHEJ-like genes. Indeed,...
Agricultural systems are particularly impacted by global climate change (CC), responsible for the introduction of multiple environmental stressors negatively affecting plant growth. Soil microbial communities crucial in agricultural practices, influencing crop performance and soil health. Human activities CC threaten biodiversity, leading to quality degradation decreasing health productivity. Among plant-beneficial microorganisms, mycorrhizal fungi widespread terrestrial ecosystems,...
Abstract Some bacterial species are important members of the rhizosphere microbiome and confer protection to host plant against pathogens. However, our knowledge multitrophic interactions determining ecological fitness these biocontrol bacteria in their highly competitive natural niche is still limited. In this work, we investigated molecular mechanisms underlying between B. velezensis, considered as model plant-associated beneficial Bacillus genus, Pseudomonas a rhizosphere-dwelling...
