Cotton is a vital fiber crop for the global textile industry, but rising temperatures due to climate change threaten its growth, quality and yields. Heat stress disrupts key physiological biochemical processes, affecting carbohydrate metabolism, hormone signaling, calcium gene regulation expression. This review article explores cotton's defense mechanism against heat stress, including epigenetic regulations transgenic approaches, with focus on genome editing tools. Given limitations of traditional breeding, advanced omics technologies such as GWAS, transcriptomics, proteomics, ionomics, metabolomics, phenomics CRISPR-Cas9 offer promising solutions developing heat-resistant cotton varieties. highlights need innovative strategies ensure sustainable production under change.

MicroRNAs in Plants Development and Stress Resistance

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: April 21, 2025

ABSTRACT Plant growth and development are governed by a rigorously timed sequence of ontogenetic programmes. MicroRNAs (miRNAs), class short noncoding RNAs, function as master regulators gene expression targeting mRNAs for cleavage or direct translational inhibition at the posttranscriptional level in eukaryotes. Numerous miRNA molecules that control significant agronomic properties plants have been found. On one hand, miRNAs target transcription factors (TFs) to determine plant structure, such root development, internode elongation, leaf morphogenesis, sex determination nutrient transition. other alter levels adapt biological abiotic stresses, including fungi, bacteria, viruses, drought, waterlogging, high temperature, low salinity, deficiencies, heavy metals stresses. To fully understand role plants, we review regulatory stress resistance. Beyond that, propose novel can be effectively further studied with artificial (amiRNA) tandem mimics (STTM) delivery vitro used improve crop yield agricultural sustainability.
