AGL2 — Asparagus officinalis

Summary

A4U43_C04F14700 (AGL2) on asparagus chromosome 4 encodes a K-box domain-containing protein with transcription regulator activity, histone H3K27me2/H3K27me3 demethylase activity, DNA helicase activity, and ATP hydrolase activity. It is associated with maintenance of floral organ identity, regulation of double fertilization, negative regulation of seed maturation, release of seed from dormancy, fruit abscission, and cellular water homeostasis. The gene is linked to numerous floral and reproductive traits including carpel shape, floral organ length, petal number, stamen morphology, seed coat color and hardness, fruit ripening, and plant male sterility. It is also linked to carotenoid accumulation, ethylene biosynthesis, floral transition, and seed longevity. Related genes in other species are linked to endothelium formation, seed coloration, and carpel identity.
