Abstract

Abiotic stresses are the most critical factors that may lead to reduced yield in the agricultural field. The response of plants to various environmental stresses has been an important topic in transcriptome studies. Integrated analysis of the drought stress-related microarray dataset was performed by R packages and 675 down and 493 up-regulated genes were identified. Up and down-regulated genes mostly belonged to the photosynthesis and hormones biosynthesis processes, respectively. Based on KEGG analysis, in plant hormone signal transduction, key genes including Aux/IAA, SAUR, TMK1/4 and TAA1 genes as up-regulated genes in aux in biosynthesis, A-ARR gene as up-regulate gene in cytokinine and salicylic acid biosynthesis were identified, respectively. In addition, in MAPK signaling, ChiB was identified as down-regulated gene in ethylene biosynthesis and MPK7/14 as up-regulated gene in ABA biosynthesis. Next, in photosynthesis, PsbS, PsbP, Psb28 and PsbQ genes in PSII; PsaK and PsaH genes in PSI and also in DNA replication, FEN1 as up-regulate gene were identified. The drought-resistant genes obtained from this research can be used to improve important agricultural products and medicinal plants in the medical industry using genetic engineering.
