The application of molecular techniques is rapidly transforming the study of plant systematics. The precision they offer enables researchers to classify plants heretofore not subject to rigorous classification and thereby to obtain a clearer picture of evolutionary relationships. Molecular Systematics of Plants is arranged both conceptually and phylogenetically to accommodate the interests not only of general systematists, but also those of people interested in a particular plant family. The first part discusses molecular sequencing; the second reviews restriction site analysis and the sequencing of mitochondrial DNA. A third section details the analysis of ribosomal DNA and chloroplast DNA. The following section introduces model studies involving well-studied families such as the Onagraceae, Compositae, and Leguminosae. The book concludes with a section addressing theoretical topics such as data analysis and the question of morphological vs. molecular data.
