Other claims from this paper (9)
- Observation Allozyme, cpDNA and morphological evidence supported three Wolffiella sections.
- Observation Species relationships were broadly similar across allozyme and cpDNA trees and plastid partitions.
- Observation Both nonsynonymous and synonymous substitutions were greater in matK than rbcL.
- Observation The synonymous substitution rate in matK was similar to the noncoding region rate.
- Observation All partitions, including coding regions, showed some homoplasy.
- Observation Biogeographical reconstruction placed Wolffiella origin in Africa followed by movement and radiation in the Americas.
- Observation cpDNA data rejected two alternative biogeographical hypotheses.
- Observation Two major dispersal events could explain the present Wolffiella distribution.
- Observation Wolffiella dispersal was limited relative to other Lemnaceae genera.
