Abstract excerpt
We described previously a mutation in maize, hcf106, caused by the insertion of a Mu1 transposon. When the Mu transposon system is in an active phase, hcf106 conditions a nonphotosynthetic, pale green phenotype. However, when the Mu system is inactive (a state correlated with hypermethylation of Mu elements), the plant adopts a normal phenotype despite the continued presence of the transposon within the gene. The...
