Multiomics Profiling Unveils Key Genes and Metabolites Involved in the Salt Tolerance of Gossypium hirsutum.

ABSTRACT:

Background

Salt stress is a primary abiotic constraint on cotton growth, significantly impairing yield and fiber quality.

Methods

To elucidate the regulatory mechanisms underlying salt stress responses in Gossypium hirsutum, we performed transcriptomic and metabolomic profiling at multiple time points following salt treatment.

Results

We identified 33,975 differentially expressed genes (DEGs), with significant enrichment in pathways related to plant hormone signal transduction, amino acid metabolism, and starch and sucrose metabolism. K-means clustering grouped the DEGs into six expression modules corresponding to distinct response stages. Additionally, UPLC-MS analysis identified 6292 metabolites-spanning lipids, carbohydrates, and amino acids-and revealed sub
