The Role of the COP/DET/FUS Genes in Light

Within the context of this genetic model, it is not surprising that all severe mutations also lead to a fusca phenotype, since anthocyanin accumulation is one of the lightinducible traits that increases quantitatively with higher light intensity. Therefore, a complete loss of function of these repre ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
