A possible hot spot for Ac insertion in the maize P gene

Mol Gen Genet. 1991 Nov;230(1-2):329-31. doi: 10.1007/BF00290684.


We have analyzed the footprints left by a single Ac transposable element during its intragenic transposition to different positions in the maize P gene. One site appears to have been visited twice by transposons, indicating that it may be an insertion hot spot. Implications of this finding for the origin of the P-vv allele are discussed. Analysis of transposon footprints may prove generally useful for establishing pedigree relationships among gene alleles.
