Abstract
Plant quality, growth, yield and productivity are repeatedly affected by
different abiotic stresses. It sometimes becomes a major upcoming threat to food
security when the stress is on some staple crops. Stress-associated gene expression or
no expression leads to abiotic stress tolerance, which is an outcome of complex signal
transduction networks. Different plants have evolved with diverse, complex signaling
networks concerning abiotic stresses. With the advancement of bioinformatics and
functional genomics, in particular, many researchers have identified many genes
related to abiotic stress tolerance in different crops, which are being used as a
promising improvement in abiotic stresses. Different techniques of genome editing also
play an important role in combating abiotic stresses. This chapter represents the
knowledge regarding stress-tolerant mechanisms using technologies related to the field
of functional genomics and may benefit the researchers in designing more efficient
breeding programs and eventually for the farmers to acquire stress-tolerant and high-yielding crops to raise their income in the future.
