Abstract
We analyzed sequence variation for the alcohol dehydrogenase (
Adh) gene family in
Carex section
Acrocystis (Cyperaceae) to reconstruct
Adh gene trees for
Acrocystis species and to characterize the structure of the
Adh gene family in
Carex. Two
Adh loci were included with ITS and ETS sequences in a combined Bayesian inference analysis of
Carex section
Acrocystis to gain a better understanding of species relationships in the section. In addition, we comment on how the results presented here contribute to our knowledge of the birth-death process of the
Adh gene family in angiosperms. It appears that the structure of the
Adh gene family in
Carex is complex with possibly six loci present in the gene family. Additionally, variation among
Acrocystis species within loci is quite low, and there is little phylogenetic resolution in the individual datasets. Bayesian inference analysis of the combined ITS, ETS, Adh1, and Adh2 datasets resulted in a moderately well-supported phylogenetic hypothesis of relationships in the section which is discussed in relation to previous hypotheses of relationships.
