Table II. Time-course regulation of genes assigned to cell cycle and DNA processing

Genes were classified according to molecular function in the DNA core replication machinery. The number of the hierarchical cluster for the time-course analysis is indicated for each gene, and genes were classified according to reproductive tissue expression, enrichment, and selectivity. Male and female gamete expression is according to Borges et al. (2008) and Wuest et al. (2010), respectively. Signal intensities are indicated for each time point.
