Function of Key Ion Channels in Abiotic Stresses and Stomatal Dynamics

Plant Physiology and Biochemistry, Journal Year: 2025, Volume and Issue: unknown, P. 109574 - 109574

Published: Jan. 1, 2025

Climate changes disrupt environmental and soil conditions that affect ionic balance in plants, presenting significant challenges to their survival productivity. Membrane transporters are crucial for maintaining homeostasis regulating the movement of substances across plasma organellar membranes, particularly under abiotic stresses. Among these stress-responsive mechanisms, stomata critical water loss carbon dioxide uptake, reflecting a plant's ability respond adapt stresses effectively. This review highlights role ion transporters, including both anion cation plant stress responses. It explores interplay between different channels regulatory components enable plants withstand key such as drought, salinity, heat. Moreover, we emphasized contributions three essential types - potassium, anion, calcium stress-related stomatal regulation. These orchestrate complex signaling networks allow modulate behavior maintain physiological adverse conditions. article provides valuable molecular insights into mechanisms transport regulation challenges. Thus, this offers useful foundation developing innovative strategies enhance crop resilience performance an era increasingly unpredictable harsh climates.

Exploring the Genotoxic Stress Response in Primed Orphan Legume Seeds Challenged with Heat Stress

Genes, Journal Year: 2025, Volume and Issue: 16(2), P. 235 - 235

Published: Feb. 19, 2025

The increased frequency of extreme weather events related to climate change, including the occurrence temperatures, severely affects crop yields, impairing global food security. Heat stress resulting from temperatures above 30 °C is associated with poor germination performance and stand establishment. combination climate-resilient genotypes tailored seed priming treatments might represent a reliable strategy overcome such drawbacks. This work explores potential hydropriming as tool mitigate heat-stress-mediated impact on in orphan legumes. For each tested species (Lathyrus sativus L., Pisum sativum var. arvense Trigonella foenum-graecum L.), two accessions were investigated. Germination tests performed at 25 °C, 35 40 assess heat tolerance threshold. Hydropriming was then applied test treatment seeds' ability cope stress. An alkaline comet assay Quantitative Real Time-Polymerase Chain Reaction embryos excised primed control seeds. Phenotyping seedling development stage highlighted accession-specific beneficial under conditions. In L. seeds, revealed dynamics stress-induced DNA damage accumulation, well repair patterns promoted by hydropriming. expression genes involved antioxidant response consistently responsive wave conditions accessions.

Nitric oxide-mediated thermomemory: a new perspective on plant heat stress resilience

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 28, 2025

In the intricate world of plant responses to environmental stress, concept thermomemory has emerged as a fascinating and complex phenomenon. Plants, sessile organisms, continually face challenge adapting fluctuating climates, ability “remember” prior heat stress encounters, phenomenon known is testament their remarkable adaptability. Nitric oxide (NO), versatile signaling molecule in physiology, been implicated myriad cellular processes crucial for adaptation. From its involvement stomatal regulation influence on gene expression antioxidant defense mechanisms, NO emerges central orchestrator plant’s response elevated temperatures. Exploration NO-mediated pathways provides insights into how plants not only cope with immediate but also retain memory these encounters. Unraveling molecular intricacies NO’s enhances our understanding sophisticated strategies employed by navigate changing climate, offering potential avenues innovative approaches enhancing crop resilience sustainable agriculture.
