Higher plants have developed complex mechanisms to adapt fluctuating environmental conditions with light playing a vital role in photosynthesis and influencing various developmental processes, including photomorphogenesis. Exposure ultraviolet (UV) radiation can cause cellular damage, necessitating effective DNA repair mechanisms. Histone acetyltransferases (HATs) play crucial regulating chromatin structure gene expression, thereby contributing the HATs facilitate relaxation, enabling transcriptional activation necessary for plant development stress responses. The intricate relationship between HATs, signaling pathways dynamics has been increasingly understood, providing valuable insights into adaptability. This review explores of photomorphogenesis, remodeling regulation, highlighting importance modifications responses stressors. It emphasizes need further research on individual HAT family members their interactions other epigenetic factors. Advanced genomic approaches genome-editing technologies offer promising avenues enhancing crop resilience productivity through targeted manipulation activities. Understanding these is essential developing strategies improve growth tolerance, sustainable agriculture face changing climate.

Abstract Understanding the intricate interplay between abiotic and biotic stresses is crucial for deciphering plant responses developing resilient cultivars. Here, we investigate combined effects of elevated light intensity nematode infection on tomato seedlings. Chlorophyll fluorescence analysis revealed significant enhancements in PSII quantum yield photochemical quenching under high conditions. qRT-PCR stress-related marker genes exhibited differential expression patterns leaves roots, indicating robust defense antioxidant responses. Despite root protection from light, roots showed molecular changes, including downregulation associated with oxidative stress upregulation involved signaling pathways. Transcriptome uncovered extensive gene alterations, exerting a dominant influence. Notably, response synergistically induced more differentially expressed than individual stimuli. Functional categorization upon double stimuli highlighted enrichment metabolic pathways, biosynthesis secondary metabolites, amino acid metabolism, whereas importance specific pathogenesis-related pathways decreased. Overall, our study elucidates complex to stresses, emphasizing integrated approaches stress-resilient crops face changing environmental

Exploring plant-microbe interactions in adapting to abiotic stress under climate change: a review

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Ноя. 15, 2024

Climatic change and extreme weather events have become a major threat to global agricultural productivity. Plants coexist with microorganisms, which play significant role in influencing their growth functional traits. The rhizosphere serves as an ecological niche encompassing plant roots is chemically complex environment that supports the development of diverse plant-interactive microbes. Although plant-microbe interactions been extensively investigated however, limited exploration made how abiotic stresses affect structure assembly microbial communities rhizosphere. This review highlights climate influence on growth, traits, communities. It explores mechanisms for mitigating stress, such removing reactive oxygen species (ROS), regulating antioxidant activity indole-3-acetic acid (IAA) production, controlling growth-inhibitory ethylene levels through colonization by bacteria producing ACC deaminase. Additionally, we elaborated systematic communicatory network steered hormonal crosstalk root exudation, can modulate initiate dialogues between plants surrounding ultimately promotes chemotactic movement microbes towards rhizosphere, facilitating early colonization. Finally, reviewed recent advancements understanding foster resilience under stress.
