Abstract excerpt
Paramutation is an interaction between alleles that leads to a heritable change in the expression of one allele. In B'/B-I plants, B-I (high transcription) always changes to B' (low transcription). The new B' allele retains the low expression state in the next generation and paramutates B-I at a frequency of 100%. Comparisons of the structure and expression of B' with that of a closely related allele that does...
