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.
