WRI — Arabidopsis thaliana

Summary

AT3G54320 (WRI1, WRINKLED 1) encodes a DNA-binding transcription factor of the AP2/ERF domain family. In Arabidopsis, WRI1 is associated with seed oil biosynthesis, including fatty acid composition, oleic acid content, and lipid production. The gene is also linked to pollen intine formation, regulation of lipogenesis, triglyceride metabolism, regulation of glycolytic process, auxin breakdown, and activation of cutin anabolism. Additional associations include seed weight, seed size, seed dormancy, embryo development, leaf dry weight, starch and sugar content, root length, flowering time, and responses to light, UV-B, and abscisic acid. The protein localizes to the nucleus, cytosol, and ubiquitin ligase complexes. Related genes in other species are linked to grain yield, reproductive development, and oil biosynthesis.
