ANT — Arabidopsis thaliana

Summary

AT4G37750 (ANT, also known as AINTEGUMENTA) encodes a DNA-binding transcription factor containing an AP2/ERF domain, localised to the nucleus. In Arabidopsis, ANT is associated with the regulation of seed development and seed size, secondary growth, meristem initiation, organogenesis, and hormone transport. It is linked to positive regulation of auxin biosynthesis, cytokinin breakdown, and malonyl-CoA anabolism. ANT is associated with numerous traits including flower diameter, floral organ size, petal number, leaf length, root weight, seed weight and yield, shoot growth angle, and disease and salt tolerance. It is also associated with ovule and integument development, cell proliferation, leaf vein architecture, and drought tolerance. Studies of related genes in other species link the family to leaf shape.
