EXPRESSION
ORGANISM
UNIPROT
LITERATURE
enzyme transcription is at its highest level during the late stage of fruit ripening (131 days after anthesis)
-
ethylene treatment differentially stimulates SPS gene expression, a reverse GCCbox, ACCGCCG, ethylene responsive element is located within the SPS promoters of the three cultivars
-
no significant correlation exists between the relative expression of sps and protein 14-3-3
SPS activity is positively correlated with sucrose and negatively correlated with hexose sugars
-
sucrose induces the enzyme, high sugar cultivars show increased transcript expression and enzyme activity of SPS compared to low sugar cultivars at all developmental stages. SPS activity is positively correlated with sucrose and negatively correlated with hexose sugars
