DAO — Oryza sativa Indica Group

Summary

BGIOSGA014888 (DAO) in Indica rice encodes a 2-oxoglutarate-dependent dioxygenase with indole-3-acetaldehyde oxidase, gibberellin 2-oxidase, and gibberellin 20-oxidase activities. This gene is associated with auxin breakdown and cellular auxin homeostasis, gibberellin catabolism and biosynthesis, and the ascorbate-glutathione cycle. It has been linked to regulation of growth, flower development, defense response, and response to light stimulus. The protein localizes to the cytoplasm, nucleus, and endoplasmic reticulum. Associations with photosynthetic rate and chlorophyll content have been noted. Studies of related genes in other species connect the family to lateral root development and emergence, root hair length, auxin homeostasis, and pollen fertility. Sequence similarity links the family to traits including plant height, root length, adventitious root number, test weight, stem diameter, salinity tolerance, and net photosynthetic rate.
