Abstract Plants are capable of assembling beneficial rhizomicrobiomes through a “cry for help” mechanism upon pathogen infestation; however, it remains unknown whether we can use nonpathogenic strains to induce plants assemble rhizomicrobiome against invasion. Here, used series derivatives Pseudomonas syringae pv. tomato DC3000 elicit different levels the immune response Arabidopsis and revealed that two induced soil-borne legacy, demonstrating similar triggering effect as wild-type DC3000....
Abstract Background MicroRNAs (miRNAs) are a class of short, endogenous non-coding small RNAs that have ability to base pair with their target mRNAs induce degradation in plants. miR394a/b conserved and its gene LCR ( LEAF CURLING RESPONSIVENESS ) encodes an F-box protein S KP1- C ullin/ DC53- F -box) but whether involved regulation plant response abscisic acid (ABA) abiotic stresses is unknown. Results Mature miR394 precursor shown be slightly induced by ABA. By contrast, expression...
Rhizosphere bacteria always compete intensely for ecological niches, employing various strategies to inhibit the growth of microbial competitors. One such strategy, contact-dependent inhibition (CDI), involves direct delivery toxic proteins into competing neighboring by a secretion system, leading their growth. However, function CDI competition in natural environment remains unclear. In this study, we examined role type VII system (T7SS) substrate LXG domain-containing protein rhizobacterium...
Fruit and seed development in plants is a complex biological process mainly involved input biosynthesis of many storage compounds such as proteins oils. Although the basic biochemical pathways for production metabolites are well characterized, their regulatory mechanisms not fully understood. In this study, we functionally identified rapeseed (Brassica napus) miR394 with its target gene Brassica napus LEAF CURLING RESPONSIVENESS (BnLCR) to dissect role during fruit development. Transgenic...
The collective behavior of bacteria is regulated by quorum sensing (QS). Autoinducer-2 (AI-2) a common QS signal that regulates the both Gram-positive and Gram-negative bacteria. Despite plethora processes described to be influenced AI-2 in diverse bacteria, AI-2-regulated Bacilli are relatively unexplored. Here, we describe novel function for Bacillus velezensis SQR9 related sporulation. inhibited initiation sporulation through phosphatase RapC DNA binding regulator ComA. Using biochemistry...
Measuring bacterial colonization on Arabidopsis thaliana root is one of the most frequent experiments in plant-microbe interaction studies. A standardized method for measuring rhizosphere necessary to improve reproducibility. We first cultured sterile A.thaliana hydroponic conditions and then inoculated cells at a final concentration OD600 0.01. At 2 days post-inoculation, tissue was harvested washed three times water remove uncolonized cells. The roots were weighed, colonized collected by...
Summary Niche colonization is the key for bacterial adaptation to environment, and competition iron largely determines root by rhizosphere microbes. Pathogenic beneficial symbiotic bacteria use various unique secretion systems support plant or acquire limited resources from environment. However, ubiquitous nonsymbiotic rhizobacteria have never been reported a system facilitate colonization. Here, we show that type VII (T7SS) of rhizobacterium Bacillus velezensis SQR9 contributes Knocking out...
Abstract Collective behavior of bacteria is regulated by quorum sensing (QS). Bacterial cells sense the density population and induce corresponding traits developmental processes. Autoinducer-2 (AI-2) a common QS signal that regulates both Gram-positive Gram-negative bacteria. In spite plethora processes described to be influenced AI-2 in diverse bacteria, AI-2-regulated Bacilli are relatively unexplored. Previously, we demonstrated root colonization Bacillus velezensis SQR9, well-studied...
