MOLECULAR RESPONSES AND GENOMIC CROP IMPROVEMENT POTENTIAL
After sensing decreasing water potential in surroundings, roots triggers
various signaling pathways of transcription and transportation in
aboveground and underground parts for activating defense responses
(Opitz et al., 2016; Sengupta et al., 2011; Y. Yang et al., 2020).
Modification in RSA to drought is dependent on intense signaling
pathways and gene expressions (Janiak et al., 2016). In the following
subsections we have discussed genes involved in controlling
physiological responses in plants and various QTLs involved in drought
responses.
