Abstract excerpt
Although genetic imprinting was discovered in maize 40 years ago, its exact extent in the triploid endosperm remains unknown. Here, we have analyzed global patterns of allelic gene expression in developing maize endosperms from reciprocal crosses between inbreds B73 and Mo17. We have defined an imprinted gene as one in which the relative expression of the maternal and paternal alleles differ at least fivefold in...
