Mechanisms limiting the geographical range of the parasitic weed Orobanche crenata
Agriculture, Ecosystems & Environment, 2007Factors and mechanisms limiting the geographical range of the root parasitic plant Orobanche crenata (crenate broomrape) were investigated and the risk of a spread beyond its current distribution area was assessed. Information on distribution and ecophysiology of O. crenata was gathered from literature and laboratory studies.

Biodiversity in Orobanche crenata in the Mediterranean region - A review
2004The study of population genetic diversity of Orobanche species is of great importance since the understanding of the variability within and between pathogenic populations is essential if selection programs need to target sources of resistance. According to Orobanche crenata, isozymes and DNA based markers have been used to determine the level of ...

The effect of nitrogenous compounds on in vitro germination of Orobanche crenata Forsk.
Weed Research, 1996SummaryThe effect of nitrogen (ammonium, urea and nitrate), applied during a conditioning or germination phase, on germination of Orobanche crenata Forsk, seeds was investigated in vitro. Ammonium sulphate (8 mM) applied during conditioning in combination with the nitrification inhibitor nitrapyrin, reduced germination of seeds from 46% to 26%. A lower

Crenatoside: a novel phenylpropanoid glycoside from Orobanche crenata.
Planta medica, 1993A new phenylpropanoid glycoside, crenatoside, as well as the known phenylpropanoid, acteoside, have been isolated from the aerial parts of Orobanche crenata. Their structures have been determined by spectroscopic methods as well as by means of chemical evidence.

Locating quantitative trait loci associated with Orobanche crenata resistance in pea
Weed Research, 2004Summary Orobanche crenata (broomrape) is a root parasite that represents the major constraint for pea (Pisum sativum) cultivation in the Mediterranean area and the Middle East. The efficacy of available control methods is minimal and breeding for O. crenata resistance is considered the most promising strategy of control.

Mapping of quantitative trait loci for resistance to Orobanche crenata in pea
2005Orobanche crenata (crenate broomrape) is a root parasite that represents the major constraint to pea production in Mediterranean areas (Rubiales et al., 1999). Only incomplete levels of resistance to broomrape have been identified in pea germplasm so far, suggesting that it is a polygenic trait. Higher levels of resistance have been found in nonadapted

Genetic diversity in Orobanche crenata populations from Spain and Israel
2001The genetic variation among Orobanche crenata populations from Spain and Israel has been studied. ISSR radiolabelled amplification products have been used and subjected to an analysis of molecular variance (AMOVA). Most of the genetic diversity was attributable to differences among individuals within a population, which is consistent with the ...
