Gene names were kept consistent with names used in previous publications or derived from the names of the respective homologs (yeast names are given in the S.c. column, where available). The Tnb column gives the numbers of cognate cDNAs and ESTs supporting the gene structure. The AltS column indicates evidence for alternative splicing, including alternative donor site (AltD), alternative acceptor site (AltA), alternative position (AltP, both acceptor and donor sites are different), exon skipping (ExonS), and intron retention (IntronR). Chromosomal duplication indicates a known chromosome duplication region. Functional groups of proteins are separated by long lines spanning all columns. Different members in the group are separated by short lines starting at the Arabidopsis gene name. Genes duplicated in Arabidopsis are clustered together with no line between them. Dash line separate the Prp19 complex from other 35S U5 associated proteins and * indicates proteins in that complex.
