plants is a priority in the current period of the continually changing climate.

The expansion of -omics techniques has provided significant tools for

promoting successful study in this area, allowing researchers to investigate

a growing variety of species, tolerant, and susceptible genotypes. These are

comprehensive, multidimensional methods depending on molecular analysis

on the genomes, transcriptomes, proteomes, and metabolomes platform are

at the present possible, allowing researchers to better understand important

molecular components of abiotic stress responses. Bioinformatics is now

essential in information generator, excavator, as well as incorporator, to
