  1. Only clusters with zero ESTs originating from the 2N library are shown. The number of 1N EST reads in each cluster and the P-value for significance of the difference between libraries are shown. When no Swiss-Prot homolog was detected, ID and homology values for the top Uniprot homolog are given (indicated by an asterisk), or the CDD name and homology values are given (indicated by †). Clusters are arranged by KOG class. Clusters in bold were chosen for RT-PCR validation. Additional data file 4 gives a complete list of all clusters predicted to be 1N-specific by statistical comparison of libraries.
