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.

Sexual reproduction in plants under high temperature and drought stress

Cell Reports, Journal Year: 2025, Volume and Issue: 44(3), P. 115390 - 115390

Published: March 1, 2025

SummaryClimate-change-induced extreme heat and drought increasingly threaten plant growth development, with a particularly significant impact on sexual reproduction. Heat stress can disrupt key stages of reproduction, including flowering time, gametophyte pollination, seed formation, leading to infertility substantial yield reductions in crops. This review systematically summarizes the latest research effects various reproduction proposes specific strategies mitigate agricultural hazards posed by these stresses. By providing an in-depth analysis underlying mechanisms regulatory networks, this offers theoretical basis for advancing fundamental optimizing practices address severe challenges climate change presents agriculture.Graphical abstract
