Gene Details:

• MSU gene ID: LOC_Os10g39420
• RAPdb gene ID: Os10g0539600
• Gene Symbol: SPK
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Antisense SPK transformants lacked the ability to accumulate storage products such as starch, but produced watery seed with a large amount of Suc instead, as the result of an inhibition of Suc degradation.
• Rice SPK, a Calmodulin-Like Domain Protein Kinase, Is Required for Storage Product Accumulation during Seed Development: Phosphorylation of Sucrose Synthase Is a Possible Factor.
• Rice SPK, a calcium-dependent protein kinase, is expressed uniquely in the endosperm of immature seed, and its involvement in the biosynthetic pathways of storage products was suggested.
• A gene encoding a calcium-dependent seed-specific protein kinase (SPK) is abundantly expressed in developing rice seeds (Kawasaki, T et al.
