BUD2 — Cucumis sativus

Summary

CsBUD2 (CSA_3G150200) in cucumber (Cucumis sativus) encodes an S-adenosylmethionine decarboxylase (SAMDC, EC 4.1.1.50), an enzyme with adenosylmethionine decarboxylase activity that also exhibits DNA-binding transcription factor and protein-binding activities. The gene is associated with polyamine biosynthesis, including spermidine and spermine anabolism, and with induced systemic resistance, viral genome replication, plant organ development, and salt stress response. It localizes to the cytosol and nucleus. CsBUD2 is associated with leaf margin morphology, leaf size and shape, flower development, net photosynthetic rate, quantum yield, respiration rate, and male sterility. It is also linked to plant architecture, axillary bud outgrowth, root architecture, shoot architecture, plant height, drought tolerance, and meristem development. Related genes in other species link the family to leaf blade development, lateral organ development, cell proliferation, xylem differentiation, and reactive oxygen species accumulation.
