Published: Feb. 17, 2022

In plants, salicylic acid (SA) is a hormone that mediates plant’s defense against pathogens. SA also takes an active role in response to various abiotic stresses, including chilling, drought, salinity, and heavy metals. addition, recent years, numerous studies have confirmed the important of plant morphogenesis. this review, we summarize data on changes root morphology following treatments under both normal stress conditions. Finally, provide evidence for maintaining balance between responses morphogenesis development, presence crosstalk with other hormones during process.

The importance of rhizomicrobiome in plant development, nutrition acquisition and stress tolerance is unquestionable. Relevant genes corresponding to the above functions also regulate construction. Deciphering molecular regulatory network plant-microbe interactions could substantially contribute improving crop yield quality. Here, gene-related nutrient uptake, biotic abiotic resistance, which may influence composition function microbial communities, are discussed this review. In turn, microbes on expression functional genes, thereby growth immunity, reviewed. Moreover, we have specifically paid attention techniques methods used link rhizomicrobiome. Finally, propose further explore mechanisms signalling pathways microbe-host gene interactions, potentially be for managing health agricultural systems.

Beneficial and pathogenic plant‐microbe interactions during flooding stress

Plant Cell & Environment, Journal Year: 2022, Volume and Issue: 45(10), P. 2875 - 2897

Published: July 22, 2022

The number and intensity of flood events will likely increase in the future, raising risk flooding stress terrestrial plants. Understanding effects on plant physiology plant-associated microbes is key to alleviate sensitive species ecosystems. Reduced oxygen supply main constrain its associated microbiome. Hypoxic conditions hamper root aerobic respiration and, consequently, hydraulic conductance, nutrient uptake, growth development. Hypoxia favours presence anaerobic rhizosphere roots with potential negative due their pathogenic behaviour or soil denitrification ability. Moreover, physiological metabolic changes induced by may also cause dysbiotic endosphere microbial composition. holobiont (i.e., host microbiome) can be mitigated once displays adaptive responses uptake. Stress relief could arise from positive effect certain beneficial microbes, such as mycorrhiza dark septate endophytes. More research needed explore spiralling, feedback if we want promote tolerance a perspective.

RIN enhances plant disease resistance via root exudate-mediated assembly of disease-suppressive rhizosphere microbiota

Molecular Plant, Journal Year: 2023, Volume and Issue: 16(9), P. 1379 - 1395

Published: Aug. 10, 2023

The RIPENING-INHIBITOR (RIN) transcriptional factor is a key regulator governing fruit ripening. While RIN also affects other physiological processes, its potential roles in triggering interactions with the rhizosphere microbiome and plant health are unknown. Here we show that microbiome-mediated disease resistance via root exudation, leading to recruitment of microbiota suppress soil-borne, phytopathogenic Ralstonia solanacearum bacterium. Compared wild-type (WT) plant, mutants had different exudate profiles, which were associated distinct changes composition diversity. Specifically, relative abundances antibiosis-associated genes pathogen-suppressing Actinobacteria (Streptomyces) clearly lower rin mutants. composition, diversity, suppressiveness microbiomes could be restored by application 3-hydroxyflavone riboflavin, exuded much concentrations mutant. Interestingly, RIN-mediated effects on exudates, Actinobacteria, suppression evident from seedling stage, indicating plays dual role early assembly disease-suppressive late development. Collectively, our work suggests that, while complex trait driven between microbiome, pathogen, it can indirectly manipulated using "prebiotic" compounds promote microbiota.

Bacterial tolerance to host-exuded specialized metabolites structures the maize root microbiome

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(44)

Published: Oct. 25, 2023

Plants exude specialized metabolites from their roots, and these compounds are known to structure the root microbiome. However, underlying mechanisms poorly understood. We established a representative collection of maize bacteria tested tolerance against benzoxazinoids (BXs), dominant bioactive in exudates plants. In vitro experiments revealed that BXs inhibited bacterial growth strain- compound-dependent manner. Tolerance selective antimicrobial depended on cell wall structure. Further, we found native isolated tolerated better compared nonhost Arabidopsis bacteria. This finding suggests adaptation host plant. Bacterial 6-methoxy-benzoxazolin-2-one (MBOA), most abundant metabolite rhizosphere, correlated significantly with abundance BX-exuding roots. Thus, strain-dependent largely explained pattern Abundant generally MBOA, while low microbiome members were sensitive this compound. Our findings reveal plant is an important competence determinant for colonization. propose root-derived mechanism determining host-specific microbial communities.
