The ability of pigeonpea crop to cope with drought and temperature depends on flexible mechanisms in genome which remodels expression of specific genes. To understand molecular mechanisms involved in response to above mentioned abiotic stresses, we have analyzed transcriptional and genomic changes in the pigeonpea genome. In the case of drought 51 genes were selected for expression profiling on three pigeonpea lines having different levels of drought tolerance and haplotype analysis across reference set (292 lines). Whereas, role of temperature in fertility transition of pollens studied in a temperature sensitive male-sterile line following RNA-seq approach. Detailed analysis through qRT-PCR and re-sequencing data (for drought) and RNA-seq (for temperature) revealed promising candidate genes for conferring abiotic stress tolerance in pigeonpea.
