Insight into gene regulatory networks involved in sesame (Sesamum indicum L.) drought response

Drought is one of the most common environmental stresses affecting crops yield and quality. Plants’ responses to drought are controlled by regulatory mechanisms. Sesame an important oilseed crop that likely faces during its growth due growing in semi-arid arid areas. Despite this importance, there little information about sesame mechanisms against stress. In study, highly differentially expressed genes were identified using in-silico transcriptome analysis two genotypes (one sensitive tolerant) under Interactions between regulators including Transcription Factors (TF) microRNAs (miRNA) predicted bioinformatics tools then related networks constructed. A total 117 TFs 133 miRNAs might be involved stress with approach. Key detected network analysis. Regulatory modules response extracted from integrated MCODE algorithm, explore relationships. Finally, some drought-tolerance-related examined qRT-PCR contrasting conditions. Interestingly, studied showed a different expression pattern tolerant genotype compared sensitive. Taken together, our results suggest miR530/TGA1/CER1, miR319/NAC29L, miR171/SUC2L play key roles tolerance regulating wax biosynthesis, leaf senescence, sugar transport drought, respectively. Overall, drought-related along their relationships could valuable candidates for future studies breeding programs on enhancing
