The influence of the holoparasite Cuscuta campestris Yuncker on the growth and photosynthesis of Mikania micrantha H.B.K. was studied. The results indicate that C. campestris infection significantly reduced the light use efficiency and light saturation point of the host. It significantly reduced the net photosynthetic rate (P(n)) of the 1st and 8th mature leaves of M. micrantha at light saturat...

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...

The present investigation was carried out to study the relationship between presence of cytotoxic compounds in Ocimum basilicum, Alhagi maurorum, Calendula officinalis and their parasite Cuscuta campestris. The cytotoxic activity of the pure compounds was performed by MTT assay against breast cancer cell lines (MCF-7 and MDA-MB-231) and normal breast cell line (MCF 10A). The induction of apopto...

Parasitic plants can adversely influence the growth of their hosts by removing resources and by affecting photosynthesis. Such negative effects depend on resource availability. However, at varied resource levels, to what extent the negative effects on growth are attributed to the effects on photosynthesis has not been well elucidated. Here, we examined the influence of nitrogen supply on the gr...

Some natural compounds of plants including phenols and alkaloids induce mitosis depressive that are blocked cell division. Field dodder (Cuscuta campestris Yunck.) and eastern dodder (Cuscuta monogyna Vahl.) are the most widespread obligatory parasitic species. In the present study, end of summer 2015, field dodder and eastern dodder are collected from Alhagi maurorum Medik. host and Vine (Viti...

The genus Cuscuta (dodder) is composed of parasitic plants, some species of which appear to be losing the ability to photosynthesize. A molecular phylogeny was constructed using 15 species of Cuscuta in order to assess whether changes in photosynthetic ability and alterations in structure of the plastid genome relate to phylogenetic position within the genus. The molecular phylogeny provides ev...
