Beat the heat: need for research studying plant cell death induced by extreme temperatures

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Summary Extreme temperatures surpassing 45°C can cause widespread plant damage and mortality, with severe consequences for ecosystem health, agricultural productivity, urban greenery, thus negatively impacting human well‐being. The global land area experiencing regular heatwaves is increasing, this trend expected to continue the foreseeable future. Despite alarming scenario, molecular mechanisms underlying thermotolerance responses extreme heat‐induced are not fully understood. As cells basic building blocks of plant, studies at cellular level required elucidate fine‐tuned signaling pathways regulating cell death survival under high heat stress, thereby generating knowledge needed better understand temperature whole level. Well‐established model systems that allow accurate measurement quantification stress‐induced programmed have a strong potential enable multifactorial studies, including use regimes informed by natural settings combinatorial stress experiments. gained as result inform development effective mitigation strategies. Studying how cope aligned One Health approach, several United Nations Sustainable Development Goals, is, therefore, research demands urgent attention.

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.

Elucidating the Role of SlBBX31 in Plant Growth and Heat-Stress Resistance in Tomato

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(17), P. 9289 - 9289

Published: Aug. 27, 2024

Heat stress inhibits plant growth and productivity. Among the main regulators, B-box zinc-finger (BBX) proteins are well-known for their contribution to photomorphogenesis responses abiotic stress. Our research pinpoints that SlBBX31, a BBX protein harboring conserved domain, serves as suppressor of heat tolerance in tomato (
