摘      要：Background:The cotton crop is universally considered as protein and edible oil source besides the major contributor of natural fiber and is grown in tropical and subtropical regions around the world Unpredicted environmental stresses are becoming significant threats to sustainable cotton production,ultimately leading to a substantial irreversible economic ***-activated protein kinase(MAPK)is generally considered essential for recognizing environmental stresses through phosphorylating downstream signal pathways and plays a vital role in numerous biological ***:We have identified 74 MAPK genes across cotton,41 from ***,19 from ***,whereas 14 have been identified from *** MAPK gene-proteins have been further studied to determine their physicochemical characteristics and other essential *** this perspective,characterization,phylogenetic relationship,chromosomal mapping,gene motif,cis-regulatory element,and subcellular localization were carried *** on phylogenetic analysis,the MAPK family in cotton is usually categorized as A,B,C,D,and E *** to the results of the phylogenic relationship,cotton has more MAPKS genes in Clade A than Clade *** cis-elements identified were classified into five groups(hormone responsiveness,light responsiveness,stress responsiveness,cellular development,and binding site).The prevalence of such elements across the promoter region of these genes signifies their role in the growth and development of *** GHMAPK genes(GH_A07G1527,GH_D02G1138,GH_D03G0121,GH_D03G1517,GH_D05G1003,GH_D11G0040,and GH_D12G2528)were selected,and specific tissue expression and profiling were performed across drought and salt *** expressed that six genes were upregulated under drought treatment except for GH_D11G0040 which is *** all the seven genes have been upregulated at various hours of salt stress ***:RNA sequence and qPCR results showe
