SAMDC — Oryza sativa Indica Group

Summary

BGIOSGA008607 (SAMDC, OiSAMDC) on chromosome 2 of Indica rice encodes an S-adenosylmethionine decarboxylase (EC 4.1.1.50) with adenosylmethionine decarboxylase activity, and is also annotated for DNA-binding transcription factor activity and protein binding. The gene is associated with spermidine, spermine and polyamine anabolism, the ascorbate-glutathione cycle, detoxification, signal transduction, response to cold, viral genome replication, plant organ development, and homeostasis. It localises to the cytosol and nucleus. Observed phenotypes link it to chilling and general stress. Associations with traits include plant height, chlorophyll content, photosynthetic rate, leaf size and margin morphology, flower development, male sterility, meristem development, abscisic acid content, and salt stress tolerance. Related genes in other species are associated with lateral organ and leaf blade development and cell proliferation.
