Abstract

Gene networks offer a strong perspective for better understanding of gene functions associated with complex biological traits. A gene regulatory network (GRN) is comprised of the regulatory elements which interact together to regulate the transcriptional and translational processes within the cell. GRNs involve the network of genes and proteins and molecular interactions that regulate those genes and proteins. GRNs govern the way a plant responds to various environmental cues. Thus, GRNs are the key to understand the interaction between the plant’s genotype and environment. Elucidation of plant GRNs is important for plant resistance and adaptability under external environmental stressors. Serious attempts are being made to characterize these GRNs and modulate them in order to get the desired trait in crop plants. In this chapter, we will discuss the structure, recent advances, and factors influencing the GRNs under various environmental stresses and major challenges for future researches.
