Phylogenetic Analysis Of Palisota (Commelinaceae) Using Chloroplast And Nuclear Regions, Alexandra H. Crum
Masters Theses
Palisota (Commelinaceae) differs from other Commelinaceae genera in androecial and pollen characters, a fleshy berry-type fruit, and anatomical characters. Palisota has been divided into two sections based on uniseriate vs. biseriate seed arrangement. Molecular phylogenetic analyses in Commelinaceae have placed Palisota near the base within the family, although its precise position is unclear. We sequenced chloroplast (matK, rbcL, rps16, and trnL-trnF, psbI-psbK, atpB-rbcL, atpF-atpH and psbA-trnH intergenic spacers) and nuclear (AT103) regions in 15 of approximately 26 species of Palisota and 15 outgroup species. Phylogenetic analyses were performed using maximum likelihood and Bayesian methods, with the …
