Two new lignan glycosides from the seeds of Cuscuta chinensis.
Two new lignan glycosides, 2'-hydroxyl asarinin 2'-O-β-D-glucopyranoside (cuscutoside C, 1) and 2'-hydroxyl asarinin 2'-O-β-D-apiofuranosyl-(1 → 2)-[β-D-glucopyranosyl-(1 → 6)]-β-D-glucopyranoside (cuscutoside D, 2), were isolated from the seeds of Cuscuta chinensis Lam., along with six...
High conservation of a 5' element required for RNA editing of a C target in chloroplast psbE transcripts.
We investigated psbE sequences from many plant species to determine in what lineage(s) editing of psbE C214 emerged and whether the cis-element identified in tobacco is conserved in plants with a C214. The GCCGUU sequence is present at a high frequency in plants that carry a C214 in psbE. However, S...
Antibacterial activity of Cuscuta reflexa stem and Corchorus olitorius seed
The methanol extracts of Cuscuta reflexa stem and Corchorus olitorius seed showed a broad spectrum of antibacterial activity.
Calcium signaling during the plant-plant interaction of parasitic Cuscuta reflexa with its hosts.
We have studied Ca(2+) spiking in tomato and tobacco during infection with C. reflexa. In our recently published study Ca(2+) signals were monitored as bioluminescence in aequorin-expressing tomato plants after the onset of C. reflexa infestation. Signals at the attachment sites were observed from 3...
The influence of the holoparasitic plant Cuscuta campestris on the growth and photosynthesis of its host Mikania micrantha.
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...
Effect of Cuscuta reflexa Roxb on androgen-induced alopecia.
The petroleum ether extract of C. reflexa and its isolate is useful in treatment of androgen-induced alopecia by inhibiting the enzyme 5alpha-reductase....
[Effect of total flavones from Cuscuta chinensis on expression of Th type-1/Th type-2 cytokines, serum P and PR in abortion rats model]
In the deciduas of model group, IL-4 and IL-10 cytokine contens were clearly lower than that of normal pregnancy group. The difference was notable(P < 0.05), In the deciduas of model group, IFN-gamma and TNF-alpha cytokine contents were clearly higher than that of normal pregnancy group. The differe...
Relatedness affects competitive performance of a parasitic plant (Cuscuta europaea) in multiple infections.
We examined whether parasite relatedness affects competition between parasitic plants (Cuscuta europaea) that share common host plants (Urtica dioica). We infected hosts with two parasitic plants that were either half-siblings or nonrelated. Relative size asymmetry between the competing parasites wa...
Chemical stress induced by heliotrope (Heliotropium europaeum L.) allelochemicals and increased activity of antioxidant enzymes.
The aims of this study were to evaluate the allelopathic potential of heliotrope on some biochemical processes of dodder. The preliminary experiments revealed that the effect of aqueous extract of leaves of heliotrope is higher than its seeds and roots. So, the aqueous extract of leaves was used in...
Studies on brain biogenic amines in methanolic extract of Cuscuta reflexa Roxb. and Corchorus olitorius Linn. seed treated mice.
The methanolic extract of both Cuscuta reflexa stem and Corchorus olitorius seed showed marked protection against convulsion induced by chemoconvulsive agents in mice. The catecholamines contained were significantly increased in the processed extract treated mice. The amount of GABA, which is most l...
