Role of Inducible Promoters and Transcription Factors in Conferring Abiotic Stress-Tolerance in Small Millets

摘要: Millets are a diverse group of small-seeded annual C4 Panicoid grasses cultivated as food and fodder crops mainly grown in poor and marginal subtropical and tropical regions globally. Generally, the millets are subjected to various abiotic stresses, like drought, heat, waterlogging, and lodging which affect the overall crop yield significantly. Plants exhibit several complex mechanisms to combat such adverse stress conditions. During this time, the gene expressions of stress-responsive genes are either up or downregulated, and several signal cascades are modulated causing an altered accumulation of osmoprotectants. During this signal transduction, transcription factors (TFs) directly regulate the expression of stress-associated genes via serving as molecular switches. In this chapter, we identified TFs across the genomes of millets for which the whole genome and gene repertoire are available. Also, a brief …
