General Information

EC Number General Information Comment Organism
2.4.1.14 additional information expression of all the SPS genes, particularly that of SPS1 and SPS11, tends to be higher at night when the activation state of the SPS proteins is low, and the mRNA levels of SPS1 and SPS6 are negatively correlated with sucrose content. The temporal patterns of SPS gene expression and sugar content under continuous light conditions suggest the involvement of endogenous rhythm and/or sucrose sensing in the transcriptional regulation of SPS genes, overview Oryza sativa Japonica Group
