SPK — Oryza sativa Indica Group
Summary
BGIOSGA029394 (symbol SPK, also known as TAC1) on chromosome 9 of Indica rice encodes a protein of the TILLER ANGLE CONTROL 1 family. The gene is associated with shoot architecture, particularly tiller angle, tiller formation, and erect growth, and has been connected to domestication and breeding traits. It is linked to branching morphogenesis, phyllotactic patterning, geotropism, circadian rhythm, and auxin signaling, and its product localises to the nucleus. Associations also include grain yield, cold tolerance, heterosis, and lateral shoot orientation. Related genes in other species link the family to leaf angle, leaf shape, plant height, tiller number, and drought tolerance.
