Wheat is an important food crop grown worldwide and used as staple food in many countries. Its
production is affected by several factors including abiotic stresses and drought is one of the most
damaging and frequently occurring abiotic stresses. Several efforts have been made to address and
cope with it at morphological, physiological and molecular levels, have been summarized. Different
morphological and physiological traits identified through successive efforts include osmotic
adjustment, cell membrane stability and stomatal conductance and showed positive correlation with
drought tolerance. Some quantitative trait loci have also been discovered in wheat genome on
chromosome 4A that showed significant association with this mechanism. Proteomic and gene
functional analysis revealed the genes involved in vital biological pathways (e.g., reactive oxygen
species scavenging, etc.) and showed significant correlation with drought tolerance. Therefore, the
information generated through both the QTLs and gene functional analysis could be utilized to
achieve drought tolerance in wheat.
