Abstract

WRINKLED 1 (WRI1), a member of the AP2/EREBP class of transcription factors, regulates carbon allocation between the glycolytic and fatty acid biosynthetic pathways and plays important roles in other biological events. Previous studies have suggested that post-translational modifications and interacting partners modulate the activity of WRI1. We systematically summarised the structure of WRI1 as well as its molecular interactions during transcription and translation in plants. This work elucidates the genetic evolution and regulatory functions of WRI1 at the molecular level and describes a new pathway involving WRI1 that can be used to produce triacylglycerols (TAGs) in plants.

Additional keywords: carbon allocation, fatty acid biosynthetic pathway, genetic evolution, post-translational modifications.
