Exogenous Melatonin Enhances Cold Tolerance by Regulating the Expression of Photosynthetic Performance, Antioxidant System, and Related Genes in Cotton

Plants, Journal Year: 2024, Volume and Issue: 13(15), P. 2010 - 2010

Published: July 23, 2024

In China, cotton is a significant cash crop, and cold stress negatively impacts the crop's development, production, quality formation. Recent studies have shown that melatonin (MT) can alleviate damage to plants under promote good growth development. this study, morphological physiological changes induced by exogenous pretreatment on 'Xinluzao 33' seedlings were examined investigate its defensive effects. The results showed 100 μM MT improved resistance of most significantly. It also wilting state stress, greatly increased photosynthetic rate (Pn), stomatal conductance (Gs), maximum photochemical efficiency (Fv/Fm), performance index (PIabs) 116.92%, 47.16%, 32.30%, 50.22%, respectively, mitigated adverse effects low-temperature. addition, supplementation substantially reduced accumulation superoxide anion (O

Genome-Wide and Expression Pattern Analysis of the HIT4 Gene Family Uncovers the Involvement of GHHIT4_4 in Response to Verticillium Wilt in Gossypium hirsutum

Genes, Journal Year: 2024, Volume and Issue: 15(3), P. 348 - 348

Published: March 9, 2024

Chromatin remodelers are essential for regulating plant growth, development, and responses to environmental stresses. HIT4 (HEAT-INTOLERANT 4) is a novel stress-induced chromatin remodeling factor that has been less studied in abiotic stress resistance, particularly cotton. In this study, we conducted comprehensive analysis of the members gene family Gossypium hirsutum using bioinformatics methods, including phylogenetic relationships, organization, transcription profiles, connections, selection pressure, response. A total 18 genes were identified four cotton species, with six upland Based on evolutionary relationships shown tree, protein sequences classified into distinct subgroups. Furthermore, chromosome mapping determine genomic locations these visually represented structural characteristics G. hirsutum. addition, predicted regulatory elements an repetitive collinearity among species. Moreover, calculated Ka/Ks ratio homologous assess pressure acting HIT4. Using RNA-seq, explored expression patterns barbadense. Through weighted co-expression network (WGCNA), found GHHIT4_4 belonged MEblue module, which was mainly enriched pathways such as DNA replication, phagosome, pentose glucuronate interconversions, steroid biosynthesis, starch sucrose metabolism. This module may regulate mechanism resistance Verticillium wilt through various metabolic pathways. performed heterologous overexpression GH_D11G0591 (GHHIT4_4) tobacco, results showed significant reduction disease index compared wild type, higher levels transgenic tobacco. After conducting VIGS (virus-induced silencing) experiment cotton, indicated silencing had impact, weakened, internode length plants significantly decreased by 30.7% while number true leaves increased 41.5%. qRT-PCR enhanced indirectly PAL, 4CL, CHI genes. The subcellular localization revealed predominantly distributed mitochondria nucleus. study offers preliminary evidence involvement lays foundation further research

Characterization of Strubbelig-Receptor Family (SRF) Related to Drought and Heat Stress Tolerance in Upland Cotton (Gossypium hirsutum L.)

Agronomy, Journal Year: 2024, Volume and Issue: 14(9), P. 1933 - 1933

Published: Aug. 28, 2024

Cotton is one of the world’s leading fiber crops, but climate change, drought, heat, and salinity have significantly decreased its production, consequently affecting textile industries globally. To acclimate to these environmental challenges, a number gene families involved in various molecular, physiological, hormonal mechanisms play crucial roles improving plants response abiotic stresses. One such family GhSRF, Strubbelig-Receptor (SRF), member leucine-rich repeat (LRR-V) group. This encodes transmembrane receptor-like kinases (LRR-RLKs) not yet been explored cotton. Arabidopsis thaliana sequences were used as queries identify homologs cotton, with subsequent support from literature functional prediction through online data. In current study, comprehensive genome-wide analysis cotton was conducted, identifying 22 SRF putative proteins encoded by genes. We performed detailed proteins, including phylogeny, motif structure characterization, promoter analysis, mapping on chromosomes, duplication events, chromosomal sub-cellular localization. Expression genes under drought heat stress conditions using publicly available RNAseq The qRT-PCR results showed elevated expression GhSRF2, GhSRF3, GhSRF4, GhSRF10, GhSRF22 stress. So, it could be speculated that may role tolerance These findings helpful breeding programs for development climate-resilient cultivars.
