Summary
The wx m-9 autonomous controlling element mutation produces either a single or doublet type protein in 20 day endosperm, depending on the dosage of Ac. The single protein observed in one dose Ac endosperm is the product of wx m-9 to Wx revertants. The doublet observed in two and three dose Ac endosperm is the product of the Ac-containing, partially suppressed wx m-9 gene. Mutual exclusion of the activities of the wx m-9 gene and its included Ac element is postulated. A competition model is presented to account for the unexpected Ac dosage effect.
