Drought, heat, high light and salt stresses are particularly concerning for agronomy in arid and semiarid regions. To cope with these adverse conditions, plants regulate specific stress-inducible genes that encode proteins involved in stress metabolism. Studies focused on gene regulation under specific conditions are important for bioengineering of crops with improved yield and quality under, for example, stressful conditions. In this sense, the purpose of the current study was to identify genes involved with the most important abiotic stresses in arid and semiarid conditions (drought, salinity, heat, and high light intensity) through bioinformatic approaches. Lists of genes responsive to water deprivation, high light intensity, heat, and salt stress were collected from specific gene ontology databases (GO:0009414, GO:0009644, GO:0009408, and GO:0009651, respectively) of Arabidopsis thaliana (Arabidopsis), Oryza sativa (rice), Zea mays (maize), Hordeum vulgare (barley), Triticum aestivum (common wheat), Solanum lycopersicum (tomato), Glycine max (soybean), and Medicago truncatula (barrel medic) through the Genevestigator software. First, responsible genes were listed separately for each plant species and each GO code. Next, the lists were combined to identify which genes are jointly responsive to all analysed stress conditions among the chosen plant species. The results show that genes responsive to salt stress are in highest amount among the analysed GO codes, followed by heat, drought, and high light intensity. Venn’s diagrams revealed that a total of 8 genes from all the plants studied are concomitantly responsive to water deprivation, high light intensity, heat, and salt stress. These genes were identified as cold-regulated 15a (cor15a), phototropin 2 (phot2), eid1-like 3 (edl3), heat shock protein 90-7 (hsp90.7). Surprisingly, hsp90.7 orthologous genes appeared as a concomitant responsive gene to the four abiotic stresses in five of the eight chosen plant species for this work, indicating that this gene is a clear marker for arid and semiarid conditions. Interestingly, no obvious network interactions among these genes were found by STRING analysis. In addition, the occurrence of genes responsive to at least three combined abiotic stressful conditions and their possible relation with other biological processes and molecular mechanisms were also analysed in this study through publicly-available experimental datasets and gene ontology grouping. The results obtained in this study shows the identification of genes with high potential as markers to study plant responses against the most important abiotic stresses in arid and semiarid regions: drought, salinity, heat, and high light intensity. Moreover, the identification of these genes may contribute for further plant improvement to cope with arid and semiarid conditions through bioengineering."
