As climate change events become more frequent, drought is an increasing threat to agricultural production and food security. Crop rhizosphere microbiome root exudates are critical regulators for adaptation, yet our understanding on the bacterial communities exudate composition as affected by stress far from complete. In this study, we performed 16S rRNA gene amplicon sequencing widely targeted metabolomic analysis of soil two contrasting rice genotypes (Nipponbare Luodao 998) exposed stress.A reduction in plant phenotypes was observed under drought, inhibition greater roots than shoots. Additionally, exerted a negligible effect alpha diversity communities, but obviously altered their composition. particular, led significant enrichment Actinobacteria decrease Firmicutes. We also found that abscisic acid clearly higher whereas lower jasmonic L-cystine concentrations. genotypes, variations traits drought-tolerant genotype 998 after were smaller those Nipponbare. Interestingly, triggered increase Bacillus, well upregulation most organic acids downregulation all amino 998. Notably, both Procrustes Mantel test demonstrated profiles highly correlated.

Further incubation experiments showed Streptomyces regulated drought.Our results reveal drive changes compositions greenhouse condition, exudation suppression select specific may be important strategy cope drought.

With the warming global climate, drought stress is considered to be most important abiotic factor limiting plant growth and yield in world. Drought has serious impacts on crop production. Many researchers have studied influences of production physiology; however, few combined root exudates with root-associated microbiomes for their mutual effects under conditions. In this review, we systematically illustrate impact microbiomes, then discuss regulation host helping adapt drought. Finally, construct a framework connections between plant, exudates, microbiome. We hope review can provide some significant guidelines promote study resistance plants association rhizosphere microbiota.

Abiotic stress poses a severe danger to agriculture since it negatively impacts cellular homeostasis and eventually stunts plant growth development. stressors like drought excessive heat are expected occur more frequently in the future due climate change, which would reduce yields of important crops maize, wheat, rice may jeopardize food security human populations. The microbiomes varied taxonomically organized microbial community that is connected plants. By supplying nutrients water plants, regulating their physiology metabolism, microbiota helps plants develop tolerate abiotic stresses, can boost crop yield under stresses.

Abstract Root-associated microbiomes contribute to plant growth and health, are dynamically affected by development changes in the soil environment. However, how different fertilizer regimes affect quantitative microbial assembly effect remains obscure. Here, we explore temporal dynamics of root-associated bacteria soybean using microbiome profiling (QMP) examine its response unbalanced treatments (i.e., lacking either N, P or K) role sustaining after four decades fertilization. We show that exhibit strong succession during development, bacterial loads largely increase at later stages, particularly for Bacteroidetes. Unbalanced fertilization has a significant on rhizosphere bacteria, absence N community diverges from fertilized plants, while impedes total load turnover bacteria. Importantly, SynCom derived low-nitrogen-enriched cluster is capable stimulating growth, corresponding with stabilized productivity fertilizer. These findings provide new insights highlight key ecological prospects sustainable agricultural management.

Abstract The root-associated microbiota plays an important role in the response to environmental stress. However, underlying mechanisms controlling interaction between salt-stressed plants and are poorly understood. Here, by focusing on a salt-tolerant plant wild soybean ( Glycine soja ), we demonstrate that highly conserved microbes dominated Pseudomonas enriched root rhizosphere of plant. Two corresponding isolates confirmed enhance salt tolerance soybean. Shotgun metagenomic metatranscriptomic sequencing reveal motility-associated genes, mainly chemotaxis flagellar assembly, significantly expressed salt-treated samples. We further find roots stressed secreted purines, especially xanthine, which induce motility isolates. Moreover, exogenous application for xanthine non-stressed results enrichment, reproducing shift root. Finally, mutant analysis shows related gene cheW is required toward enhancing tolerance.
