Hormonal and transcriptomic regulation of drought adaptation in barley roots and leaves.

ABSTRACT: Drought poses a significant threat to global crop productivity and food security. In this study, we aimed to elucidate the impact of drought on transcriptional regulation and alternative splicing in barley (Hordeum vulgare), and to determine whether these transcriptomic alterations correlate with changes in hormonal profiles. We hypothesized that drought stress induces extensive reprogramming of gene expression, including alternative splicing events, and that these molecular responses are accompanied by tissue-specific shifts in hormone levels, ultimately underpinning adaptive responses in both leaves and roots. To test this, we performed RNA-seq and comprehensive hormone profiling on leaves and roots sampled at 25 days after planting under both optimal and drought conditions. Our analysis
