BUD2 — Cucumis sativus

Summary

CsBUD2 (CSA_2G036680) on cucumber chromosome 2 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 linked to polyamine biosynthesis, including spermidine and spermine anabolism, and to induced systemic resistance, viral genome replication, plant organ development, and salt 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. Phenotypic associations include plant architecture, axillary bud outgrowth, root architecture, and plant growth. Studies of related genes in other species link the family to leaf blade development, lateral organ development, and reactive oxygen species accumulation.
