Molecular mechanism of drought stress tolerance in barley (Hordeum vulgare L.) via a combined analysis of the transcriptome data

One of the main issues addressed by phytology in recent years has been plant tolerance mechanisms for abiotic stress. No combined analysis made to identify genes involved drought stress tolerance. The meta-analysis microarray data related was analysed R software packages and showed 3 029 upregulated 017 downregulated genes. were mostly protein, response, Cys2His2 Zinc Finger Transcription Factor (C2H2 zinc finger TF). mainly late embryogenesis abundant basic leucine zipper (bZIP) TF. common gene ontology (GO) terms metabolic process, response stimulus, cellular photorespiration. up down meta-differential expressed (meta-DEGs) belonged those following Kyoto Encyclopedia Genes Genomes (KEGG) pathways including: biosynthesis secondary metabolites, hormone signal transduction, mitogen-activated protein kinase (MAPK) signalling pathway, RNA degradation. Moreover, genes, TFs with a high percentage Teosinte branched1/Cincinnata/proliferating cell factor (TCP), helix loop-helix (bHLH) bZIP. Next, hub thiamine thiC, 4-hydroxyphenylpyruvate dioxygenase, ribose-5-phosphate isomerase precursor heat shock protein. associated elongation Ts, aldehyde dehydrogenase, trigger factor. Finally, from present compared previous studies on qRT-PCR results their expressions confirmed. Based findings current study, novel insights into molecular can be provided various candidate introduced barley breeding.
