AGL2 — Cucumis melo

Summary

MELO3C022316.2, also known as CmAGL2, encodes a SEPALLATA 3-like MADS-box protein on melon chromosome 12. The product is a transcription regulator with RNA polymerase II-specific DNA-binding, transcription coactivator and corepressor activities, protein dimerization activity, and histone H3K27me2/H3K27me3 demethylase activity. It is associated with the maintenance of floral organ identity, regulation of double fertilization, negative regulation of seed maturation and floral organ abscission, fruit abscission, cellular water homeostasis, and abscisic acid breakdown. The gene has been linked to numerous traits including flower and carpel morphology, floral organ length and size, fruit length and ripening, seed coat color and hardness, plant male sterility, and osmotic adjustment capacity. It localizes to the nucleus, cytoplasm, plastid, and plasmodesma.
