AT3G24650 — Arabidopsis thaliana

Summary

AT3G24650, also known as ABI3 (ABA INSENSITIVE 3) in Arabidopsis thaliana, encodes a B3 DNA-binding domain transcription factor of the LEC2-like family. The protein exhibits Hsp90 binding, transcription coactivator activity, and sequence-specific DNA binding. ABI3 is associated with seed longevity, iron distribution in seed, abscisic acid responsiveness, oil accumulation, freezing tolerance, seed degreening, and late embryogenesis-abundant gene expression. It is associated with entry into dormancy, pre-harvest sprouting, acquisition of desiccation tolerance, regulation of lipogenesis, and regulation of triglyceride catabolic process. The gene has been linked to traits including germination ratio, seedling vigor, drought recovery, seed protein content, vivipary, and photoperiod sensitivity. Studies of related genes in other species link it to fruit growth and development and bacterial disease response.
