SAMDC — Oryza sativa Indica Group

Summary

BGIOSGA029738 (symbol SAMDC, also known as OiSAMDC) on chromosome 9 of Indica rice 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 associated with polyamine, spermidine and spermine anabolism, the ascorbate-glutathione cycle, detoxification, signal transduction, viral genome replication, plant organ development, and homeostasis. It is linked to chilling stress, salt stress tolerance, male sterility, fertility, leaf margin morphology, leaf size, flower development, meristem development, plant height, photosynthetic rate, chlorophyll content, and abscisic acid content. The protein localises to the cytosol and nucleus. Related genes in other species link the family to lateral organ and leaf blade development and cell proliferation.
