TL;DR: The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.
Journal ArticleDOI
The evolution of plant sexual diversity.
TL;DR: The integration of phylogenetic, ecological and population-genetic studies have provided new insights into the selective mechanisms that are responsible for major evolutionary transitions between reproductive modes.
Journal ArticleDOI
A comparative analysis of pollen limitation in flowering plants
TL;DR: The results suggest that the influence of phylogenetic history on the intensity of pollen limitation was not particularly strong, and significant variation in the degree of pollen limitations was demonstrated among seven angiosperm families suggesting some phylogenetic component to the phenomenon.
Journal ArticleDOI
Multiple Multilocus DNA Barcodes from the Plastid Genome Discriminate Plant Species Equally Well
Aron J. Fazekas,Kevin S. Burgess,Prasad Kesanakurti,Sean W. Graham,Steven G. Newmaster,Brian C. Husband,Diana M. Percy,Mehrdad Hajibabaei,Spencer C. H. Barrett +8 more
TL;DR: Resolution to the contentious debate on plant barcoding should involve increased attention to practical issues related to the ease of sequence recovery, global alignability, and marker redundancy in multilocus plant DNA barc coding systems.
