Abstract
Climate change has been a threat to food security
challenges. Climate change presents an additional stress on
food security challenges as it affects production of food in
many ways. Among various stresses, drought is a big
concern and rising at an alarming rate with climate change.
Scientific approaches are being tried to understand the
mechanisms of drought stress. The emergence of new
molecular biology approaches and new sequencing as well
as phenotyping platforms good research progress has been
made in regard to drought and drought resistance
mechanisms via identification of quantitative trait loci or
genes responsible for drought tolerance mechanisms
through Qtl mapping, Family based Qtl mapping, Linkage
disequilibrium, Structural and Functional genomics
approaches. Genome wide selection methods have been
used for the current world concern of drought which will
eventually lead to climate resilient crops and will solve the
problem of food insecurity in near future. Huge data are
being derived from genome wide selection (GWS) studies at
the transcriptomics, proteomics and metabolomics levels,
but how efficiently to explore and exploit these data to
extract the essential functional pathways or networks for
genetic improvement of drought resistance remains a
significant challenge.
