Abstract Background Some of the most difficult phylogenetic questions in evolutionary biology involve identification of the free-living relatives of parasitic organisms, particularly those of...
Barkman, Todd J., Martins, Talline R., Sutton, Elizabeth, Stout, John T.
We used a combined evolutionary and experimental approach to better understand enzyme functional divergence within the SABATH gene family of methyltransferases (MTs). These enzymes catalyze the...

Evidence for positive selection on the floral scent gene Isoeugenol-O-methyltransferase (2003)
Isoeugenol-O-methyltransferase (IEMT) is an enzyme involved in the production of the floral volatile compounds methyl eugenol and methyl isoeugenol in Clarkia breweri (Onagraceae). IEMT likely...

In this paper, molecular phylogenetic analyses were used to investigate a putative hybrid origin for Dendrochilum acuiferum, a species endemic to Mount Kinabalu, Sabah, Malaysia. Phylogenetic...

Mount Kinabalu, (Sabah, Malaysia) is the youngest (ca. 1.5 million yrs old) and highest (4,095 m) mountain between the Himalayas and Irian Jaya, Indonesia. Because of this combination of youth and...

Plant phylogenetic estimates are most likely to be reliable when congruent evidence is obtained independently from the mitochondrial, plastid, and nuclear genomes with all methods of analysis. Here,...

All parasites are thought to have evolved from free-living ancestors. However, the ancestral conditions facilitating the shift to parasitism are unclear, particularly in plants because the...
