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.

Insights into the Epigenetic Basis of Plant Salt Tolerance

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(21), P. 11698 - 11698

Published: Oct. 31, 2024

The increasing salinity of agricultural lands highlights the urgent need to improve salt tolerance in crops, a critical factor for ensuring food security. Epigenetic mechanisms are pivotal plant adaptation stress. This review elucidates complex roles DNA methylation, histone modifications, variants, and non-coding RNAs fine-tuning gene expression response It emphasizes how heritable changes, which do not alter sequence but significantly impact phenotype, contribute this adaptation. methylation is notably prevalent under high-salinity conditions associated with changes that enhance resilience salt. Modifications histones, including both acetylation, directly linked regulation salt-tolerance genes. presence such as H2A.Z, altered stress, promoting environments. Additionally, RNAs, miRNAs lncRNAs, intricate regulatory network also underscores importance understanding these epigenetic developing stress memory enhancing tolerance.

Identification of the Novel Small Compound Stress Response Regulators 1 and 2 That Affect Plant Abiotic Stress Signaling

Biomolecules, Journal Year: 2024, Volume and Issue: 14(9), P. 1177 - 1177

Published: Sept. 19, 2024

Abiotic stresses, such as drought, salinity, and extreme temperatures, limit plant growth development, reducing crop yields. Therefore, a more comprehensive understanding of the signaling mechanisms responses plants to changing environmental conditions is crucial for improving sustainable agricultural productivity. Chemical screening was conducted find novel small compounds that act regulators abiotic stress pathway using ABA-inducible transgenic reporter line. Small molecules called response (SRRs) were isolated by synthetic library composed 14,400 compounds, affecting phenotypes seed germination, root growth, gene expression in multiple stresses. Seeds pretreated with SRR positively affected germination rate radicle emergence Arabidopsis tomato under conditions. The SRR-priming treatment enhanced transcriptional stress-responsive genes subsequent salt stress. isolation SRR1 SRR2 will provide tool elucidate complex molecular networks underlying stress-tolerant responses.

Nitrogen Stress Memory in Quinoa: Maternal Effects on Seed Metabolism and Offspring Growth and Physiology

Physiologia Plantarum, Journal Year: 2024, Volume and Issue: 176(6)

Published: Nov. 1, 2024

Plants have developed various strategies to deal with abiotic stresses throughout their lifetimes. However, environmental can long-lasting effects, positively modifying plant physiological responses subsequent stress episodes, a phenomenon known as preconditioning or memory. Intriguingly, this memory even be transmitted offspring, referred "inter- transgenerational memory". Chenopodium quinoa is pseudocereal that withstand several stresses, including nitrogen (N) limitation. This research highlights the critical role of maternal N conditions in shaping and metabolic offspring. Mother plants (F0) were grown under High (HN) Low (LN) conditions. LN
