Published: June 8, 2023

Soil salinization is a severe abiotic stress that negatively affects plant growth and development, leading to physiological abnormalities ultimately threatening global food security. The condition arises from excessive salt accumulation in the soil, primarily due anthropogenic activities such as irrigation, improper land uses, overfertilization. presence of Na⁺, Cl-, other related ions soil above normal levels can disrupt cellular functions lead alterations essential metabolic processes seed germination photosynthesis, causing damage tissues even death worst circumstances. To counteract effects stress, plants have developed various mechanisms, including modulating ion homeostasis, compartmentalization export, biosynthesis osmoprotectants. Recent advances genomic proteomic technologies enabled identification genes proteins involved salt-tolerance mechanisms. This review provides short overview impact salinity on underlying mechanisms salt-stress tolerance, particularly salt-stress-responsive associated with these aims at summarizing recent our understanding tolerance providing key background knowledge for improving crops' which could contribute yield quality enhancement major crops grown under saline conditions or arid semiarid regions world.

Time-course transcriptome analysis reveals gene co-expression networks and transposable element responses to cold stress in cotton

BMC Genomics, Journal Year: 2025, Volume and Issue: 26(1)

Published: March 12, 2025

Cold stress significantly challenges cotton growth and productivity, yet the genetic molecular mechanisms underlying cold tolerance remain poorly understood. We employed RNA-seq iterative weighted gene co-expression network analysis (WGCNA) to investigate transposable element (TE) expression changes at six time points (0 h, 2 4 6 12 24 h). Thousands of differentially expressed genes (DEGs) were identified, exhibiting time-specific patterns that highlight a phase-dependent transcriptional response. While A D subgenomes contributed comparably DEG numbers, numerous homeologous pairs showed differential expression, indicating regulatory divergence. Iterative WGCNA uncovered 125 modules, with some enriched in specific chromosomes or chromosomal regions, suggesting localized hotspots for Notably, transcription factors, including MYB73, ERF017, MYB30, OBP1, emerged as central regulators within these modules. Analysis 11 plant hormone-related revealed dynamic ethylene (ETH) cytokinins (CK) playing significant roles stress-responsive pathways. Furthermore, we documented over 15,000 TEs, TEs forming five distinct clusters. TE families, such LTR/Copia, demonstrated enrichment clusters, their potential role modulators under stress. These findings provide valuable insights into complex networks response cotton, highlighting key components involved regulation. This study provides targets breeding strategies aimed enhancing cotton.
