A multitude of biotic and abiotic stress factors do harm to plants by bringing about diseases inhibiting normal growth development. As a pivotal signaling molecule, salicylic acid (SA) plays crucial roles in plant tolerance responses both stresses, thereby maintaining improving yields under stress. In view this, this paper mainly discusses the role SA stresses plants. regulates expression genes involved defense pathways, thus enhancing immunity. addition, mitigates negative effects acts as molecule induce stress-responsive synthesis stress-related proteins. also improves certain yield-related photosynthetic indexes, crop yield On other hand, with molecules, such jasmonic (JA), auxin, ethylene (ETH), so on, regulating This reviews recent advances SA’s tolerance, provide theoretical references for further studies concerning decryption molecular mechanisms improvement management

Humidity-driven ABA depletion determines plant-pathogen competition for leaf water

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Янв. 4, 2025

Abstract Bacterial phytopathogens, such as Pseudomonas syringae pv. tomato ( Pst ) DC3000, induce water-soaked lesions in the leaf apoplast under high humidity, facilitating infection. However, it remains largely unclear how plants regulate their resistance to restrict bacterial infection response humidity. Here, we demonstrate that abscisic acid (ABA)-catabolizing ABA 8’-hydroxylase, encoded by CYP707A3 , plays a critical role this Arabidopsis thaliana . Elevated humidity induces expression, which is essential for reducing levels and promoting stomatal opening, thereby limiting water-soaking following invasion. High also increases cytosolic Ca 2+ via channels CNGC2 CNGC4, with partial involvement from CNGC9, activating calmodulin-binding transcription activator CAMTA3 drive induction. DC3000 counteracts defense using type III secretion effectors, particularly AvrPtoB, water-soaking. These findings provide insights into mechanisms underlying competition between bacteria water elevated

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.

The Arabidopsis chloroplast protein HHL1 regulates AvrRpt2‐triggered immunity via light‐dependent reactive oxygen species homeostasis

Journal of Integrative Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Май 12, 2025

ABSTRACT Chloroplasts are key organelles for capturing solar energy and establishing plant immunity. During photosynthesis pathogen defense, highly redox‐active reactions take place in chloroplasts generate large amounts of reactive oxygen species (ROS). However, our knowledge chloroplast‐produced ROS biosynthesis immunity under varying light conditions is limited. Here, we report that the chloroplast‐localized protein HYPERSENSITIVE TO HIGH LIGHT 1 (HHL1) functions as a dual regulator AvrRpt2‐triggered Arabidopsis ( thaliana ), by modulating levels to activate appropriate responses infection various intensities. Under normal conditions, HHL1 positively regulates promoting AvrRpt2‐induced accumulation, initiating salicylic acid signaling, inducing expression genes encoding ROS‐scavenging enzymes. By contrast, high (HL) has an opposite role, functioning repressor these immune while HL stress attenuates These findings reveal modulates regulating homeostasis intensity‐dependent manner. Collectively, results offer insight into role crosstalk between intensity.

The occurrence of plant disease is determined by interactions among host, pathogen, and environment. Air humidity shapes various aspects physiology high has long been known to promote numerous phyllosphere diseases. However, the molecular basis how interferes with immunity favor remained elusive. Here we show that associated an "immuno-compromised" status in Arabidopsis plants. Furthermore, accumulation signaling salicylic acid (SA), important defense hormone, are significantly inhibited under humidity. NPR1, SA receptor central transcriptional co-activator SA-responsive genes, less ubiquitinated displays a lower promoter binding affinity cellular ubiquitination machinery, particularly Cullin 3-based E3 ubiquitin ligase mediating NPR1 protein ubiquitination, downregulated Importantly, low 3a/b mutant plants phenocopy gene expression susceptibility normally observed Our study uncovers mechanism which dampens major pathway provides new insights into long-observed air influence on
