Stress arising due to abiotic factors affects the plant's growth and productivity.
Among several existing abiotic stressors like cold, drought, heat, salinity, heavy
metal, etc., drought condition tends to affect the plant's growth by inducing two-point
effect, i.e., it disturbs the water balance as well as induces toxicity by disturbing
the ion homeostasis, thus hindering the growth and productivity of plants, and to
survive under this condition, plants have evolved several transportation systems that
are involved in regulating the drought stress. The role of membrane transporters has
gained interest since genetic engineering came into existence, and they were found
to be the important modulators for tolerance, avoidance, ion movements, stomatal movements,
etc. Here in this comprehensive review, we have discussed the role of transporters
(ABA, protein, carbohydrates, etc.) and channels that aids in withstanding the drought
stress as well as the regulatory role of transporters involved in osmotic adjustments
arising due to drought stress. This review also provides a gist of hydraulic conductivity
by roots that are involved in regulating the drought stress.
