Abstract

Significance

In many eukaryotes, reproduction involves contributions of genetic material from two parents. At some genes there are parent-of-origin differences in the expression of the maternal and paternal alleles of a gene and this is referred to as imprinting. The analysis of allele-specific expression in several maize hybrids allowed the comprehensive detection of imprinted genes. By comparing allelic expression patterns in multiple crosses, it was possible to observe allelic variation for imprinting in maize. The comparison of genes subject to imprinting in multiple plant species reveals limited conservation for imprinting. The subset of genes that exhibit conserved imprinting in maize and rice may play important, dosage-dependent roles in regulation of seed development.
