Huanglongbing, or citrus greening, threatens the global citrus industry. The presumptive pathogens, 'Candidatus Liberibacter asiaticus' and 'Ca. L. americanus' can be transferred from citrus to more easily studied experimental hosts by using holoparasitic dodder plants. However, the interaction between 'Candidatus Liberibacter' spp. and the dodder has not been studied. We combined quantitative ...

dodder is an obligate parasite of many plant families and among dodder species cuscuta campestris has the most diverse around the world. extensive infestation to dodder recently has been reported in some sugerbeet production regions of khorasan provinces. so, in this study greenhouse and field experiments were conducted to test and charachterize the tolerance of commercial sugarbeet varieties t...

background and objectivescommon privet (ligustrum vulgare) is one of the most important plants in landscapes of iran. this plant is adaptable to unfavorable environmental conditions, so that is cultivated widespread in urban landscape. invasion of dodder to common privet caused problems for landscape management in mashhad city in recent years. dodder is an obligate parasite of many plant famili...

weed chemical control has negative results on agroecosystems. therefore, identification of cultivars tolerant to weeds has importance in nonchemical management. so, in this study, the tolerance of some alfalfa cultivars was studied to dodder. anexperiment was conducted at research farm and laboratory of shahed university in 2011. the farm experiment was done as split plot in time in randomized ...

Dur ing an investigation of the relat ionship between the parasit ic flowering p lan t dodder (Cuscuta campestris Yuncker) and its hosts, an unusual cytoplasmic componen t was observed in cer tain of the dodder cells. Both in electron and in l ight micrographs our a t ten t ion was d rawn to the cytoplasmically rich cells at the tip of the newly initiated haustor ium, or sucker. These long cell...

parasite weeds are the most important yield reducing factors, and among them dodder (cuscuta campestris l.) is an obligate parasite of many plant families. in order to find a suitable biocontrol agent for dodder a study was conducted based on a randomized complete design with four replications at research greenhouse of faculty of agriculture, ferdowsi university of mashhad, iran during 2007-200...

Determination of 23 populations of field dodder was conducted using light and scanning electron microscopy and subsequent molecular (PCR) methods in order to fully examine the biology and ecology of Cuscuta campestris and options for its control. The effects of different temperatures and rhizobacteria (PGPR) on germination of C. campestris seeds, as well as effects of different light treatments...

Phytoplasma PoiBI is responsible for free branching in poinsettia (Euphorbia pulcherrima Wild. ex. Klotzsch). In this study, PoiBI was transmitted by dodder from poinsettia to crown-of-thorns (E. milii Des Moulins) in one out of ≈100 attempts, whereas grafting transmission was unsuccessful. PoiBI was shown to be viable in E. milii, as it was detected in the recipient plant and in its cuttings o...

It is generally correct to think of plants as the hearty autotrophs, gamely harnessing photons to make food and existing perennially (or annually) at the bottom of the food chain. However, thousands of plant species have lost the ability to feed themselves and have become adapted, instead, to live as parasites of other plants. Not surprisingly, these parasitic plants, especially witchweed root ...
