Isophasic Parasitism in Phoradendron Perredactum (viscaceae)
It is pointed out that the newly described Phoradendron perredactum Rzedowski & Calderón exhibits an advanced type of growth behavior (isophasic parasitism) that also occurs in three other, unrelated groups of parasitic flowering plants.
متن کاملNew Species of Phoradendron (Viscaceae) from Mexico and Guatemala and a Synopsis of Species in Section Pauciflorae
As presently interpreted Phoradendron sec tion Pau cifiorae consists of 15 spec ies. These mistletoes parasitize primarily conifers. We describe seven new spec ies . make sta tus changes for four species, and provide information on the hosts and di str ibution of all members of the sec tion. New species described are: Phoradendron abietinurn Wiens, on Abies durangen si s in Chihuahua, Durango, ...
متن کاملThe discovery of three genetic races of the dwarf mistletoe Arceuthobium americanum (Viscaceae) provides insight into the evolution of parasitic angiosperms.
A population genetic approach was used to explore the evolutionary biology of the parasitic angiosperm Arceuthobium americanum Nutt. ex Engelm. (Viscaceae). Arceuthobium americanum infects three principal hosts and has the most extensive geographical range of any North American dwarf mistletoe. Based on the lack of apparent morphological and phenological differences between populations of A. am...
متن کاملMassive gene loss in mistletoe (Viscum, Viscaceae) mitochondria
Parasitism is a successful survival strategy across all kingdoms and has evolved repeatedly in angiosperms. Parasitic plants obtain nutrients from other plants and some are agricultural pests. Obligate parasites, which cannot complete their lifecycle without a host, may lack functional photosystems (holoparasites), or have retained photosynthesis (hemiparasites). Plastid genomes are often reduc...
متن کاملEpiparasitism in Phoradendron durangense and P. falcatum (Viscaceae)
Phoradendron, the largest mistletoe genus in the New World, extends from temperate North America to temperate South America. Most species are parasitic on terrestrial hosts, but a few occur only, or primarily, on other species of Phoradendron. We examined relationships among two obligate epiparasites, P. durangense and P. falcatum, and their parasitic hosts. Fruit and seed of both epiparasites ...
