AGL2 — Asparagus officinalis

Summary

A4U43_C10F4820 (AoAGL2) on asparagus chromosome 10 encodes a K-box domain-containing protein with transcription regulator activity, histone H3K27me2/H3K27me3 demethylase activity, DNA helicase activity, ATP hydrolase activity, nucleosome array spacer activity, transcription coactivator activity, and transcription corepressor activity. The gene is associated with maintenance of floral organ identity, regulation of double fertilization forming a zygote and endosperm, negative regulation of seed maturation, negative regulation of floral organ abscission, fruit abscission, cellular water homeostasis, abscisic acid breakdown, regulation of proanthocyanidin anabolism, and response to biotic stimulus and silver ion. Associations include osmotic adjustment capacity, floral organ length, flower morphology trait, seed coat hardness, seed color, fruit ripening trait, plant male sterility, seed longevity, leaf shattering, and gibberellin biosynthesis trait. The protein localizes to the nucleus, cytoplasm, plastid, plasmodesma, and endosperm protein body. Studies of related genes in other species link the family to flowering, fruit ripening, drought tolerance, and floral organ development.
