Plant transcription factors control almost every stage of plant growth and stress response, and this session at PMBWC 2027 explores the gene regulatory networks they form. Transcription factors are proteins that control when and where genes are switched on or off. They regulate plant growth, organ development, flowering, hormone responses and adaptation to stress. Most transcription factors work together in networks rather than alone. Changes in transcription factors or in the DNA regions they bind to are responsible for many important differences between crop varieties, including plant shape, flowering time and fruit size. Studying how these proteins interact with each other and with their target genes helps explain how plants coordinate complex processes. New sequencing and computational tools are making it easier to map these networks on a genome-wide scale.
This session covers major transcription factor families such as zinc finger, MYB, NAC and WRKY proteins, methods for building gene regulatory networks from omics data, and the link between regulatory variation and important crop traits.
