Low-temperature stress, including chilling and freezing injuries, significantly impacts plant growth in tropical temperate regions. Plants respond to cold stress by activating mechanisms that enhance tolerance, such as regulating photosynthesis, metabolism, protein pathways producing osmotic regulators antioxidants. Membrane stability is crucial, with cold-resistant plants exhibiting higher lipid unsaturation maintain fluidity normal metabolism. Low temperatures disrupt reactive oxygen species (ROS) leading oxidative damage, which mitigated antioxidant defenses. Hormonal regulation, involving ABA, auxin, gibberellins, others, further supports adaptation. also manage balance accumulating like proline sugars.

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.
