AGL2 — Asparagus officinalis

Summary

AGL2 (AoAGL2) on asparagus chromosome 9 encodes a K-box domain-containing protein with transcription regulator activity, histone H3K27me2/H3K27me3 demethylase activity, DNA helicase activity, and RNA polymerase II-specific DNA-binding transcription factor activity. It is associated with regulation of double fertilization, maintenance of floral organ identity, negative regulation of seed maturation, fruit abscission, and cellular water homeostasis. The gene is linked to numerous floral and seed traits including carpel shape, petal number, sepal morphology, seed coat hardness and color, fruit ripening, and plant male sterility. It also connects to osmotic adjustment capacity, leaf shattering, and the vegetative-to-reproductive phase transition. Related genes in other species link the family to inflorescence branching, fruit development, seed coloration, and drought tolerance.
