Identification of candidate genes and proteins for tasseling stage drought tolerance through integrated transcriptomic and proteomic analysis approach in maize.

ABSTRACT: Drought stress, particularly at the tasseling stage, is the most devastating abiotic factor and major contributor to yield reduction in maize (Zea mays L.). Despite recent scientific advances in deciphering maize drought stress responses, the overall picture of key genes and proteins regulating maize tasseling drought tolerance remains less understood. In this study, we conducted comparative physiological, transcriptomic and proteomic analyses to monitor the changes in the leaf tissues of two contrasting maize hybrid cultivars exposed to drought stress at the tasseling stage. We identified 1701 differentially expressed genes (DEGs) in RNA-sequence runs and 424 differentially expressed proteins (DEPs) from an iTRAQ-based analysis. Mapman analysis revealed several regulatory processes influe
