Various species of Artemisia seems to hold great prospect of in-depth investigation for various biological activities, especially their effects on the central nervous and cardiovascular systems.
Chinensis seeds has an effect on renal function parameters in ischemia/reperfusion-induced acute renal failure rats.
Periodic acid Schiff staining showed that administration of ACC improved tubular damage in ischemia/reperfusion-induced ARF.

If the region is planted annually, choose plants that are not susceptible to attack by dodder, such as ornamental grasses and other monocots, including lilies.
In agricultural crops, dodder is managed by rotation to non-host crops, usage of dodder-free seed, cleaning equipment between fields, control of weed hosts, and chemical control in infested areas.
Dodder can weaken or kill plants and reduce crops yields.
The impact on the host plant varies considerably with respect to the species of dodder, the growth stage and condition of the host plant, and the time of infection.
Infected plants may also be more susceptible to diseases and insect problems.
In the spring, dodder seeds germinate near the soil surface and send up slender, thread-like twining stems varying in color from pale green to yellow or

Species of the genus are trusted as essential constituents in functional foods and traditional medicinal systems.
Various parts of several members of Cuscuta have already been found efficacious against a variety of diseases.

It is usually leafless but sometimes they have really small scale-like triangular leaves that are barely visible.
Parasitic life is an exemplory case of interaction between two species.

The roots form haustoria that infect the roots of nearby host plants.
Once the seed germinates and there is a susceptible host, it wraps itself round the plant and dissolves the surface cells of the host plant.
After that it inserts rootlike branches in to the plant called haustoria, which enable the vine to extract carbohydrates, water and nutrients from its host.
After the plant attaches to the host plant, the initial stem and root shrivels.

Dodder (cuscuta Spp) Biology And Management

One of the requirements for this type of listing is that the plant should be eradicated.
As a way to protect California’s citrus crop, this is done very rapidly when it had been discovered in the state so as to protect the state’s economically valuable citrus crop.
Saltmarsh dodder usually lives only 10 days as a non-parasitic plant if it’s unable to look for a host.
The exact length of time is influenced by temperature, humidity, as well as perhaps, the size of the initial seed.

• parasitic plant Cuscuta reflexa.
• The warnings enable co-hosts to brace themselves for insect attack and reduce their losses once an assault begins.
• Seeds require sun, warmth and moisture to germinate.

Until now, no-one had tested whether dodder could receive or transmit meaningful signals from the host to some other host through its body.
A team from the Kunming Institute of Botany led by Christian Hettenhausen and Jianqiang Wu made a decision to answer those questions.
In herbaceous plants, a group of fungi only distantly related to tree mycorrhizae provide virtually identical, if not identical, mycorrhizal services.

Nevertheless, the hybrid character of putative hybrid accessions obtained after cross in vivo and in vitro pollination had not been confirmed.

Host plants susceptible to this parasitic vine range from vegetable crops to ornamental and herbaceous garden plants; including some woody plants.
The dodder vine is therefore a disease when it successfully parasitizes its host.
Generally, host plants are weakened by dodder, not immediately killed.
Dodder plants are leafless parasitic vines, family Convolvulaceae, which grows as climbing tendrils and forming bridge between plants.
The stems of the plants wind around other plants with haustoria which interact with vascular tissue of the host and facilitate transmission of the virus from the infected to healthy plants.
The dodder may be used for experimental transmission of viruses under controlled conditions.
