LOG1 — Oryza sativa Indica Group

Summary

BGIOSGA001314 (LOG1) in Indica rice encodes a protein of the LOG family with cytokinin riboside 5'-monophosphate phosphoribohydrolase activity, as well as NADH:nitrate reductase activity, Mo ion binding, FAD binding, and mRNA binding. This gene is associated with cytokinin anabolism, nitric oxide anabolism, Moco biosynthesis, regulation of meristem development, auxin signaling, and responses to light and symbiotic fungi. It has been linked to domestication, awn development, grain filling, seed development, and stress responses including drought and biotic stress. Associations also extend to yield-related traits such as grain number, panicle traits, tiller number, root system architecture, flowering time, nitrate sensitivity and uptake, herbicide sensitivity, and stomatal function. The protein localizes to the cytosol, nucleus, plasma membrane, mitochondria, and vacuole. Studies of related genes in other species link the family to nitrate reductase activity, nitrogen use efficiency, and stress tolerance.
