Plastome Evolution in Hemiparasitic Mistletoes
Santalales is an order of plants consisting almost entirely of parasites. Some, such as Osyris, are facultative root parasites whereas others, such as Viscum, are obligate stem parasitic mistletoes. Here, we report the complete plastome sequences of one species of Osyris and three species of Viscum, and we investigate the evolutionary aspects of structural changes and changes in gene content in...
متن کاملEndocarp morphology of Iranian Celtis (Celtidaceae-Cannabaceae)
Endocarp morphology of 4 species of Iranian Celtis was examined using light and scanning electron microscopes. Macro- and micro-morphological characters were included endocarp shape, color, size, surrounding rim, ornamentation and SEM structure of the outer layer of the endocarp. Endocarp morphology of the examined specimens exhibit variation in all characters. Endocarp shape varies from globul...
متن کاملA chemotaxonomic analysis of cannabinoid variation in Cannabis (Cannabaceae).
Cannabinoids are important chemotaxonomic markers unique to Cannabis. Previous studies show that a plant's dry-weight ratio of Δ(9)-tetrahydrocannabinol (THC) to cannabidiol (CBD) can be assigned to one of three chemotypes and that alleles B(D) and B(T) encode alloenzymes that catalyze the conversion of cannabigerol to CBD and THC, respectively. In the present study, the frequencies of B(D) and...
متن کاملOenothera Plastome Mutator-Induced Chloroplast Mutant1
Plastids were isolated from a plastome mutator-induced mutant (pm7) of Oenothera hookeri and were analyzed for various physiological and biochemical attributes. No photosynthetic electron transport activity was detected in the mutant plastids. This is consistent with previous ultrastructural analysis showing the absence of thylakoid membranes in the pm7 plastids and with the observation of aber...
متن کاملPlastome data reveal multiple geographic origins of Quercus Group Ilex
Nucleotide sequences from the plastome are currently the main source for assessing taxonomic and phylogenetic relationships in flowering plants and their historical biogeography at all hierarchical levels. One major exception is the large and economically important genus Quercus (oaks). Whereas differentiation patterns of the nuclear genome are in agreement with morphology and the fossil record...
