SVP — Arabidopsis thaliana

Summary

AT2G22540 (SVP, also known as AGL22) encodes a protein with MADS-box, MEF2-like, and K-box domains. The protein exhibits transcription regulator activity, transcription corepressor activity, and RNA polymerase II transcription regulatory region sequence-specific DNA binding. SVP is associated with thermoregulation, photoperiod sensitivity, floral whorl development, floral organ formation, negative regulation of floral organ abscission, negative regulation of seed maturation, fruit abscission, secondary growth, and gibberellin catabolism. The gene is linked to grain size, harvest index, leaf area index, inflorescence branching, inflorescence height, flower number, fruit number, drought sensitivity, thermosensitivity, acid sensitivity, and abscisic acid content.
