BUD2 — Cucumis melo

Summary

MELO3C023787.2 (CmBUD2) on melon chromosome 7 encodes an S-adenosylmethionine decarboxylase (EC 4.1.1.50) with adenosylmethionine decarboxylase activity, and is also associated with DNA-binding transcription factor activity and protein binding. The gene is associated with polyamine biosynthesis and homeostasis, including spermidine and spermine anabolism, as well as plant organ development, embryogenesis, and viral genome replication. It localises to the cytosol and nucleus. CmBUD2 is associated with leaf margin morphology, leaf size and shape, flower development, male sterility, plant height, root architecture, axillary bud outgrowth, shoot architecture, photosynthetic and respiration rates, and drought tolerance. Studies of related genes in other species link the family to xylem differentiation, leaf blade development, and reactive oxygen species accumulation.
