Q3E7K4 · QQS_ARATH

Function

function

Involved in regulating carbon and nitrogen allocation to starch and protein (PubMed:25146936).

Miscellaneous

The expression of QQS varies considerably among natural accessions as well as within populations directly sampled from the wild. This variation correlates negatively with the DNA methylation level of repeated sequences located within the 5'end of the gene.
