AGL2 — Cucumis melo

Summary

MELO3C026300.2 (CmAGL2) on melon chromosome 8 encodes a MADS-box transcription factor containing a K-box domain and MEF2-like domain, with annotated transcription regulator, DNA-binding, transcription coactivator and corepressor, protein dimerization, ATP hydrolase, and histone H3K27me2/H3K27me3 demethylase activities. The gene is associated with maintenance of floral organ identity, regulation of double fertilization, negative regulation of seed maturation and floral organ abscission, fruit abscission, cellular water homeostasis, abscisic acid breakdown, galacturonan metabolism, and responses to biotic stimuli and silver ion. It is linked to traits including floral organ length and size, carpel and sepal morphology, petal number, fruit length and ripening, seed coat hardness and color, leaf shattering, plant male sterility, and osmotic adjustment capacity. Related genes in other species are linked to seed coat development, endothelium formation, and proanthocyanidin accumulation.
