YUC8 — Arabidopsis thaliana

Summary

AT4G28720, also known as YUC8 or YUCCA8, encodes a flavin-containing monooxygenase with indole-3-pyruvate monooxygenase activity (EC 1.14.13.168). The gene is associated with a wide range of biological processes including auxin anabolism, hormone metabolism, shade avoidance, secondary growth, and cell fate specification. YUC8 has been linked to numerous traits and phenotypes, such as shoot axis branching, root development, hypocotyl elongation, lateral root length, stem elongation, seed size, and cell elongation. It is also associated with stress responses, including alkaline salinity tolerance, aluminum stress tolerance, biotic stress resistance, and jasmonic acid content. Additionally, YUC8 is associated with leaf sodium concentration, lignification, and thermomorphogenesis. The protein localizes to the nucleus and is involved in cellularization, signaling, and differential growth processes.
