Food security is threatened by global warming, which also affects agricultural output. Various components of cells perceive elevated temperatures. Different signaling pathways in plants distinguish between the two types temperature increases, mild warm temperatures and extremely hot Given rising temperatures, heat stress has become a major abiotic challenge, affecting growth development various crops significantly reducing productivity. Brassica napus, second-largest source vegetable oil worldwide, faces drastic reductions seed yield quality under stress. This review summarizes recent research on genetic physiological impact Brassicaceae family, as well model Arabidopsis rice. Several studies show that extreme fluctuations during crucial stages negatively affect plants, leading to impaired reduced production. The discusses mechanisms adaptation key regulatory genes involved. It explores emerging understanding epigenetic modifications While such are limited B. contrasting trends gene expression have been observed across different species cultivars, suggesting these play complex role tolerance. Key knowledge gaps identified regarding napus.

Impact of High-Temperature Stress on Maize Seed Setting: Cellular and Molecular Insights of Thermotolerance

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(3), P. 1283 - 1283

Published: Feb. 2, 2025

Global warming poses a significant threat to crop production and food security, with maize (Zay mays L.) particularly vulnerable high-temperature stress (HTS). This review explores the detrimental impacts of elevated temperatures on development across various growth stages, analyzed within source–sink framework, particular focus seed setting yield reduction. It provides broad analysis cellular molecular responses HTS, highlighting key roles plant hormone abscisic acid (ABA) signaling, calcium chloroplast, DNA damage repair (DDR) system in maize. HTS disrupts ABA signaling pathways, impairing stomatal regulation reducing water-use efficiency, while orchestrates by activating heat shock proteins other protective mechanisms. Chloroplasts, as central photosynthesis, are sensitive often exhibiting photosystem II chlorophyll degradation. Recent studies also highlight significance DDR system, genes like ZmRAD51C playing crucial maintaining genomic stability during reproductive organ development. under conditions emerges factor contributing reduced set, although precise mechanisms remain be fully elucidated. Furthermore, examines cutting-edge genetic improvement strategies, aimed at developing thermotolerant cultivars. These recent research advances underscore need for further investigation into basis thermotolerance open door future advancements breeding crops.

ZmHSFA2B self‐regulatory loop is critical for heat tolerance in maize

Plant Biotechnology Journal, Journal Year: 2024, Volume and Issue: unknown

The growth and development of maize (Zea mays L.) are significantly impeded by prolonged exposure to high temperatures. Heat stress transcription factors (HSFs) play crucial roles in enabling plants detect respond elevated However, the genetic mechanisms underlying responses HSFs heat remain unclear. Thus, we aimed investigate role ZmHSFA2B regulating tolerance maize. Here, report that has two splicing variants, ZmHSFA2B-I ZmHSFA2B-II. encodes full-length (ZmHSFA2B-I), whereas ZmHSFA2B-II a truncated (ZmHSFA2B-II). Overexpression improved Arabidopsis thaliana, but it also resulted retardation as side effect. RNA-sequencing CUT&Tag analyses identified ZmMBR1 putative target ZmHSFA2B-I. enhanced Arabidopsis. was primarily synthesized response competitively interacted with This interaction consequently reduced DNA-binding activities homodimers promoter ZmMBR1. Subsequent investigations indicate limits transactivation tempers function ZmHSFA2B-I, thereby reducing adverse effects excessive accumulation. Based on these observations, propose alternative generates self-regulatory loop fine-tunes
