BUD2 — Solanum lycopersicum

Summary

SlBUD2 (SOLYC05G010420.2) on tomato chromosome 5 encodes an S-adenosylmethionine decarboxylase proenzyme, conferring adenosylmethionine decarboxylase activity and 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 transsulfuration, the ascorbate-glutathione cycle, and melatonin anabolism. It is linked to fruit volume and shape, leaf margin morphology, floral organ identity, flower development, stem elongation, photosynthetic and respiration rates, and oxidative stress response. Associations also include plant architecture, axillary bud outgrowth, root architecture, male sterility, and fertility. Studies of related genes in other species link the family to xylem differentiation, reactive oxygen species accumulation, leaf blade development, and cell proliferation.
