SAMDC — Oryza sativa Indica Group

Summary

BGIOSGA016698 (SAMDC, OiSAMDC) encodes an S-adenosylmethionine decarboxylase proenzyme, conferring adenosylmethionine decarboxylase activity, and is also annotated with DNA-binding transcription factor and protein-binding activities. In indica rice, this gene is associated with responses to chilling and general stress, as well as with spermidine, spermine, and polyamine biosynthesis, the ascorbate-glutathione cycle, detoxification, signal transduction, viral genome replication, plant organ development, and homeostasis. It localizes to the cytosol and nucleus. Associations with traits include leaf margin morphology, abscisic acid content, meristem development, male sterility, leaf growth, flower development, leaf size, photosynthetic rate, chlorophyll content, plant height, salt stress tolerance, and polyamine homeostasis. Studies of related genes in other species link the SAMDC family to lateral organ and leaf blade development and cell proliferation.
