MADS-box transcription factors are crucial members of regulatory networks underlying multiple developmental pathways and abiotic stress in plants. Studies on resistance-related functions genes very limited barley. To gain insight into this gene family elucidate their roles salt waterlogging resistance, we performed genome-wide identification, characterization expression analysis A whole-genome survey barley revealed 83 genes, which were categorized type I (Mα, Mβ Mγ) II (AP1, SEP1, AGL12, STK, AGL16, SVP MIKC*) lineages based phylogeny, protein motif structure. Twenty conserved motifs determined each HvMADS contained one to six motifs. We also found tandem repeat duplication was the driven force for expansion. Additionally, co-expression network 10 14 predicted response stress, proposed HvMADS11 ,13 35 as candidate further exploration stress. The extensive annotations transcriptome profiling reported study ultimately provides basis MADS functional genetic engineering other gramineous crops.
