BUD2 — Cucumis sativus

Summary

CSA_3G271360 (BUD2, SAMDC) on cucumber chromosome 3 encodes an S-adenosylmethionine decarboxylase proenzyme (EC 4.1.1.50) with adenosylmethionine decarboxylase activity, and also shows DNA-binding transcription factor activity and protein binding. The gene is associated with polyamine biosynthesis, including spermine and spermidine anabolism, and with induced systemic resistance, viral genome replication, and plant organ development. It localises to the cytosol and nucleus. BUD2 is associated with salt tolerance, leaf margin morphology, leaf size and shape, flower development, male sterility, meristem development, root architecture, axillary bud outgrowth, shoot and plant architecture, plant growth, plant development, polyamine homeostasis, and photosynthetic traits including net photosynthetic rate, quantum yield, and respiration rate. Studies of related genes in other species connect the SAMDC family to xylem differentiation, reactive oxygen species accumulation, leaf blade development, and cell proliferation.
