Explanation
|
This gene encodes a calcium-dependent seed-specific protein kinase. The genomic region consists of SPK-A and SPK-B, both of them being located on different chromosomes (Chrom. 6 and Chrom. 10). EC=2.7.11.1 AC073166, AE017116, D13436. E07613. P53682. PO:0009089; endosperm ; PO:0009010; seed. GRO:0007046; 07-milk stage. KC610844-KC610855 (O. sativa and wild rice species, partial cds). OsCDPK23 (OsCPK23) in Asano et al. 2005, Ray et al. 2007, Tanaka et al. 2006.
