PLASTID GENOMES are used in phylogenetic studies.Research Support, N.I.H., ExtramuralResearch Support, N.I.H., IntramuralResearch Support as Topic: Financial support of research activities.Genome, Viral: The complete genetic complement contained in a DNA or RNA molecule in a virus.Genome, Chloroplast: The genetic complement of CHLOROPLASTS as represented in their DNA.DNA, Chloroplast: Deoxyribonucleic acid that makes up the genetic material of CHLOROPLASTS.Scrophulariaceae: The figwort plant family of the order Lamiales. The family is characterized by bisexual flowers with tubular corollas (fused petals) that are bilaterally symmetrical (two-lips) and have four stamens in most, two of which are usually shorter.Veronica: A plant genus of the family Plantaginaceae. Members contain bis-sesquiterpene and iridoid glucosides.Chloroplasts: Plant cell inclusion bodies that contain the photosynthetic pigment CHLOROPHYLL, which is associated with the membrane of THYLAKOIDS. Chloroplasts occur in cells of leaves and young stems of plants. They are also found in some forms of PHYTOPLANKTON such as HAPTOPHYTA; DINOFLAGELLATES; DIATOMS; and CRYPTOPHYTA.Vitaceae: A plant family of the order Rhamnales, subclass Rosidae, class Magnoliopsida, best known for the VITIS genus, the source of grapes.Gene Order: The sequential location of genes on a chromosome.Genome, Plant: The genetic complement of a plant (PLANTS) as represented in its DNA.Phylogeny: The relationships of groups of organisms as reflected by their genetic makeup.Angiosperms: Members of the group of vascular plants which bear flowers. They are differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Angiosperms represent approximately 80% of all known living plants.
