AFB1 — Cucumis melo

Summary

MELO3C015898.2 (CmAFB1) on melon chromosome 2 encodes a protein with F-box and leucine-rich repeat domains, and is annotated with auxin receptor activity, auxin binding, NEDD8 transferase activity, and IP6 binding. The gene is associated with auxin signalling, SCF complex assembly, and regulation of protein-nucleus import. In melon, the related gene AFB2 has been linked to fruit ripening. Associations from other studies connect CmAFB1 to a wide range of traits including seedling cotyledon size, biomass yield, seed yield, adventitious root number, phototropism, leaf morphogenesis, root system architecture, auxin transport, and responses to heat, shade, osmotic stress, and temperature. The gene is also linked to lateral root development, embryonic pattern specification, and defense response regulation via callose deposition.
