Genetic imprinting is the epigenetic phenomenon observed in flowering plants including maize in which, an allele shows differential expression depending on the parent it is inherited. Imprinted genes are modified during gametogenesis so that only paternal or maternal allele is expressed after fertilization. This review focuses on the major processes involved in the regulation of imprinting like DNA methylation, covalent modifications of histones and chromatin remodeling citing examples of maize. This review also summarizes theimprinted genes that have been reported in maize including Fie1, Fie2, Peg1, Nrp1, Mez1, Meg1, Mee1, VIP5 and Yuc8.
