Conservation of imprinted expression across genotypes is correlated with consistency of imprinting across endosperm development in maize.

ABSTRACT: Imprinted expression is an essential process for seed viability affecting hundreds of genes in Zea mays endosperm; however, most studies have examined just one time point for analysis. The focus on single time points can limit our ability to identify imprinted genes and our ability to draw conclusions for the role of imprinting in endosperm. In this study, we examine imprinted expression across 4 time points ranging from the transition to endoreduplication from mitotic division through the beginning of programmed cell death. Additionally, we assessed imprinting variation across 8 diverse maize lines, 6 of which have never before been assessed for imprinting. Through this analysis, we identify over 700 imprinted genes with varying consistency across time points including 255 genes imprinted
