additional information | tissue specificity and diurnal change in gene expression of the sucrose phosphate synthase gene family, overview. Isozyme comparison: gene SPS1 is preferentially expressed in source tissues, whereas genes SPS2, SPS6, and SPS8 are expressed equally in source and sink tissues, mRNA levels of SPS1, SPS8, and SPS11 are considerably higher in seeds than in shoots and roots | Oryza sativa Japonica Group | - |

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 |
