SPL7 — Oryza sativa Japonica

Summary

OsSPL7 (SPL7) on rice chromosome 5 encodes a DNA-binding transcription activator with an SBP domain, localising to the nucleus and nuclear speck. It is associated with copper ion homeostasis and the cellular response to copper starvation, as well as proteolysis, RNA breakdown, carbohydrate metabolism, and signal transduction. The gene is linked to grain number, grain yield, grain shape, grain size, panicle density, tiller number, plant height, flowering time, anthesis time, vegetative growth time, leaf senescence, root morphology, and abiotic stress responses including copper sensitivity, cadmium stress, oxidative stress, and ethylene and jasmonic acid content. It is also connected to pollen viability, fertility, and flower development. Related genes in other species are linked to growth and cadmium tolerance.
