Starch content of AtPERK10 knockout plants. Starch content of the wild type phenotypes and the knockouts of the AtPERK10 gene (At1g26150), a putative protein kinase whose expression correlates with the expression of starch metabolism genes. The mutant plants have 13% more starch than WT plant (p-value = 0.045). Atperk10-3 is in Col-0 background. Col-0 is a wild type sibling. EOL: samples taken at the end of the light phase.
