ABSTRACT The increasing severity of global climate change has led to more frequent extreme high‐temperature events, significantly damaging rice yield and quality, thus posing a threat food security. Research indicates that plant‐microbe interactions can enhance plant growth overall health under adverse conditions. Therefore, this review aims explore strategies improve heat tolerance through thermophilic microorganism mediation. This paper systematically summarises the effects stress on both aboveground underground parts during its stages, identifies molecular mechanisms by which responds stress, explores potential roles microorganisms. Additionally, we existing studies microorganisms alleviate their action. Through case studies, how survival in environments regulating development, along with applications sustainable agriculture. In future, environmentally friendly efficient microbial inoculants biofertilizers are expected be developed based microbe‐mediated mechanisms, will help mitigate challenges crops face change.

Abstract The shade avoidance response triggers a dramatic promotion of elongation growth, accompanied by significant reprogramming metabolic pathways as plants seek to prevent overtopping and adapt vegetative shade. Here we demonstrate that simulated results in changes the structure composition phyllosphere bacterial microbiome. Our study uncovered shifts diversity, occurrence, abundance activity bacteria within A comparison responses both wild-type phytochrome mutants, which inherently exhibit shade-avoidance phenotype, revealed indirect host plant physiology direct light among microbiota.

(1) Background: As population growth accelerates, unsustainable practices such as excessive cutting and burning of desert plants in the transition zones between deserts oases have led to widespread vegetation loss. (2) Methods: The experiment was conducted oasis zone on southern edge Taklamakan Desert from 2010 2023 year. Among treatments included a control group (CK), spring (CS), fall (CF), (BS), flood water irrigation (FI). We used high-throughput sequencing determine soil microbial composition diversity routine laboratory methods physical chemical properties enzyme activities. (3) Results: No significant differences bacterial alpha (Chao1, Dominance, Observed_features, Pielou_e, Shannon, Simpson) across different long-term disturbance patterns. In fungi, CK treatment showed significantly higher Chao1, Observed_features indices compared BS FI. Principal component analysis revealed substantial reduction community FI, while fungal communities were lower CS BS, CF, FI; (4) Conclusions: Soil moisture content, electrical conductivity, organic carbon, activity cellobiohydrolase key factors shaping community.

ABSTRACT Plants have co‐evolved with a wide range of microbial communities over hundreds millions years, this has drastically influenced their adaptation to biotic and abiotic stress. The rapid development multi‐omics approaches greatly improved our understanding the diversity, composition, functions plant microbiomes, but how global climate change affects assembly microbiomes roles in regulating host changing environmental conditions is not fully known. In review, we summarize recent advancements community responses factors such as elevated CO 2 levels, warming, drought. We further delineate research trends hotspots plant–microbiome interactions context change, key mechanisms by which influence climate. propose that future urgently needed unravel impact genes signal molecules modulated on communities, elucidate evolutionary response plant–microbe at level, engineer synthetic mitigate effects fitness.

Microbial community dissimilarities increased increasing differences moisture, regardless of levels. Plant significantly affected bacterial fungal ambient only, protistan both reduced slopes (bacterial fungal, not protistan) functional groups, which indicates weakening relationship microbiome groups enrichment.

As global climates shift, plants are increasingly exposed to biotic and abiotic stresses that adversely affect their growth development, ultimately reducing agricultural productivity. To counter these stresses, produce secondary metabolites (SMs), which critical biochemical essential compounds serve as primary defense mechanisms. These diverse compounds, such alkaloids, flavonoids, phenolic nitrogen/sulfur-containing act natural protectants against herbivores, pathogens, oxidative stress. Despite the well-documented protective roles of SMs, precise mechanisms by environmental factors modulate accumulation under different stress conditions not fully understood. This review provides comprehensive insights into recent advances in understanding functions SMs plant emphasizing regulatory networks biosynthetic pathways. Furthermore, we explored unique contributions individual SM classes responses while integrating findings across entire spectrum diversity, providing a resilience multiple conditions. Finally, highlight emerging strategies for harnessing improve crop through genetic engineering present novel solutions enhance sustainability changing climate.
