Putative poly(A) polymerase genes in the plant lineage.

1Organism the genome of which was searched using the Phytozome database.
2Gene designations were obtained from the respective organism database web sites. Where appropriate, parenthetical notes of the reporting of complete sequences (including confirmed C-termini; see the text) and multiple alternatively-processed mRNA isoforms are included.
3Support for expression was in the form of EST sequences (EST), full-length cDNAs (fl cDNA), microarray data (array), and RT/PCR results (this study).
