CKX1 — Oryza sativa Indica Group

Summary

BGIOSGA037012 (CKX1) in Indica rice encodes a cytokinin dehydrogenase, an enzyme with cytokinin dehydrogenase activity, FAD binding, and redox activity, classified as EC 1.5.99.12. The gene is associated with cytokinin metabolism and NO storage, and its product localises to the ER, extracellular space, cytosol, and nucleus. It is linked to pathways including degradation of isopentenyladenine, regulation of leaf angle by cytokinin, shoot gravitropism, and responses to abiotic stimuli. CKX1 is associated with seed shattering, panicle number, grain shape, amylose content, panicle length, spikelet number, heterosis, grain number, grain size, plant height, and grain yield.
