▪ Abstract The chemical structures of the primary cell walls of the grasses and their
progenitors differ from those of all other flowering plant species. They vary in the complex …

A number of studies have noted that nucleotide substitution rates at the chloroplast-encoded
rbcL locus violate the molecular clock principle. Substitution rate variation at this plastid …

Most phylogenetic analyses of morphological data agree that Gnetales are a monophyletic
group related to angiosperms and Bennettitales. However, they disagree on whether these …
