BAD1 — Oryza sativa Indica Group

Summary

BGIOSGA014941 (BAD1, also known as BADH1) on chromosome 4 of Indica rice encodes an aldehyde dehydrogenase family protein with betaine-aldehyde dehydrogenase, succinate-semialdehyde dehydrogenase, and coniferyl-aldehyde dehydrogenase activities. The gene is associated with GABA catabolism, the GABA shunt, cellular detoxification of aldehydes, and the ascorbate-glutathione cycle. It is linked to responses to anoxia, desiccation, insects, and oxidative stress, as well as to systemic resistance and callose deposition. In rice, BAD1 is associated with grain size, seed development, male sterility, fungal blast resistance, and tolerance to salinity, drought, submergence, and temperature stress. The gene is also associated with amylose and protein content, grain filling, photosynthetic rate, root length, and chlorophyll content.
