Comprehensive physiological and transcriptomic insights into drought stress responses in faba bean (Vicia Faba L.).

ABSTRACT: Drought is a major limiting constraint to faba bean production worldwide, including Tunisia. However, molecular mechanisms underlying faba bean responses to drought stress are not well understood. In this context, RNA-seq was applied to investigate drought-related genes and construct a network of faba bean (Vicia faba L.) drought stress response and tolerance. Assembly of the transcriptome generated 26,728 differentially expressed genes (DEGs). Of these, 13,920 were up-regulated and 12,808 down-regulated in faba bean drought-stressed leaves. Moreover, a total of 2130 transcription factors involved in major metabolic pathways including abscisic acid (ABA)-dependent and -independent signaling pathway were identified.
