  1. Only clusters with zero ESTs originating from the 1N library are shown. The number of 2N EST reads in each cluster and the P-value for significance of the difference between libraries are shown. Homolog IDs are marked as in Table 5. Clusters are arranged by KOG class. Clusters in bold were chosen for RT-PCR validation. Additional data file 5 gives a complete list of all clusters predicted to be 2N-specific by statistical comparison of libraries.
