We initiated this review by discussing the impact of drought on plants during vegetative and reproductive phases. Then, we elaborate on the structural adaptations of plants under drought with more focus on the root architecture as roots are the primary sense organs of drought. Genomic information which helps in crop improvement programs are also discussed. Finally, we talk about various root phenotyping methods that are useful in understanding the modifications in root architecture in field conditions.
