Increased Virulence in Sunflower Broomrape (Orobanche cumana Wallr.) Populations from Southern Spain Is Associated with Greater Genetic Diversity
Orobanche cumana Wallr. (sunflower broomrape) is a holoparasitic weed that infects roots of sunflower in large areas of Europe and Asia. Two distant O. cumana gene pools have been identified in Spain, one in Cuenca province in the Center and another one in the Guadalquivir Valley in the South. Race F has been hypothesized to have arisen by separate mutational events in both gene pools. In the G...

متن کاملHost recognition of Orobanche cumana, the broomrape of cultivated sunflower
Background and aims: Most of the economically relevant parasitic weeds of the Orobanchaceae have a more or less broad host spectrum within the plant family they are adapted to. The hostreleased compounds inducing their germination were identified as so-called strigolactones and represent four-ring terpenoids derived from the carotenoid metabolism. O. cumana, a fast emerging problem of sunflow...
متن کاملFirst report of human granulocytic ehrlichiosis from southern Europe (Spain).
Emerging Infectious Diseases Vol. 6, No. 4, July–August 2000 430 During a survey of parasitic helminths of wild vertebrates from Tres Palos Lagoon, in Guerrero, Mexico, we found Gnathostoma sp. advanced third-stage larvae (AdvL3) in the skeletal muscle of several fish species. Fish were caught from March to August 1999 in Tres Palos Lagoon (16° 41' to 16° 50'N and 99° 37' to 99° 47'W), Acapulco...
متن کاملCharacterization of Resistance Mechanisms in Faba Bean (Vicia faba) against Broomrape Species (Orobanche and Phelipanche spp.)
Faba bean (Vicia faba) production in Mediterranean and Near East agriculture is severely constrained by broomrape infection. The most widely distributed broomrape species affecting faba bean is Orobanche crenata, although O. foetida and Phelipanche aegyptiaca are of local importance. Only moderately resistant cultivars are available to farmers. Rizotrons studies allowed the dissection of resist...
