Identification, characterization, and expression profiles of the GASA genes in cotton

Abstract Background GASA (Giberellic Acid Stimulated in Arabidopsis ) gene family plays a crucial role the phytohormone signaling pathway, growth and development, stress responses plants. Many homologs have been identified various Nevertheless, little is known about these proteins cotton. Results In current study, we 19, 17, 25, 33, 38 genes via genome-wide analyses of Gossypium herbaceum , G. arboreum, raimondii barbadense, hirsutum respectively, performed comprehensive bioinformatics expression analyses. According to our results, 132 shared similar protein structures were classified into four groups based on phylogenetic tree. A synteny analysis suggested that segmental duplication was key driver expansion family. Meanwhile, cis -element interaction indicated GhGASA play significant hormone responses. Transcriptomic qRT-PCR (Quantitative real time-polymerase chain reaction) revealed diverse profiles different organs under abiotic stresses, indicating some possibly participate fiber development abiotic-stress Conclusions The cotton systematically analyzed for first time this paper, it are important These results will support future exploration functions
