Paralogy and Orthology in the Malvaceae rpb2 Gene Family: Investigation of Gene Duplication in Hibiscus

Pfeil, Bernard; Brubaker, Curt L.; Craven, Lyn A.; Crisp, Michael


A sample of the second largest subunit of low-copy nuclear RNA polymerase II (rpb2) sequences from Malvaceae subfamily Malvoideae suggests that rpb2 has been duplicated early in the subfamily's history. Hibiscus and related taxa possess two rpb2 genes, both of which produce congruent phylogenetic pattems that are largely concordant with cpDNA topologies. No evidence of functional divergence or disruption was found among duplicated copies, suggesting that long-term maintenance of duplicated...[Show more]
