BUD2 — Cucumis sativus

Summary

CsBUD2 (CSA_6G062290) on cucumber chromosome 6 encodes an S-adenosylmethionine decarboxylase (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 spermidine and spermine anabolism, and with induced systemic resistance, viral genome replication, plant organ development, and salt stress response. It localises to the cytosol and nucleus. Traits linked to CsBUD2 include leaf margin morphology, leaf size and shape, flower development, male sterility, meristem development, net photosynthetic rate, quantum yield, respiration rate, and salt tolerance. Phenotypes connected to the gene encompass plant architecture, axillary bud outgrowth, root architecture, shoot architecture, plant height, and fertility. Studies of related genes in other species link the SAMDC family to fruit volume, tuber size, powdery mildew resistance, and salt tolerance.
