First Report of Dodder (Cuscuta australis) Parasitizing the Invasive Weed Ambrosia artemisiifolia in China

Distribution of Invasive Weed Ambrosia artemisiifolia L. in Croatia

Ambrosia artemisiifolia L., is an invasive alien plant in Europe that has been the subject of research of many scientifi c disciplines, particularly in last twenty years. In addition to being known as a noxious weed, it came into the public interest as a source of very strong allergenic pollen that causes allergic responses in 10% of the Croatian population, a fi gure similar to that of other E...

Stem parasitic plant Cuscuta australis (dodder) transfers herbivory-induced signals among plants.

Cuscuta spp. (i.e., dodders) are stem parasites that naturally graft to their host plants to extract water and nutrients; multiple adjacent hosts are often parasitized by one or more Cuscuta plants simultaneously, forming connected plant clusters. Metabolites, proteins, and mRNAs are known to be transferred from hosts to Cuscuta, and Cuscuta bridges even facilitate host-to-host virus movement. ...

First report of Ambrosia psilostachya from Iran: An invasive plant species establishing in coastal area of Gilan province (N Iran)

The genus Ambrosia consisting at least 40 species, with numerous intraspecific taxa (Essl et al. 2015). The first observation of Ambrosia from Iran was reported by Mozaffarian (1991).

"Antioxidant response of the invasive herb Ambrosia artemisiifolia L. to different irradiance levels"

New sesquiterpenoids from Ambrosia artemisiifolia L.

A new pseudoguaianolide 1 and two new guaiane-type sesquiterpene glucosides 2 and 3, were isolated from the aerial parts of Ambrosia artemisiifolia L together with two known sesquiterpene dilactones 4 and 5. The new compounds were determined on the basis of spectroscopic and chemical methods to be 3β-acetoxy-4β-hydroxy-1α,7α, 10β,11αH-pseudoguaia-12,8β-olide (1), 1β,7β,9β,10β,13αH-guaia-4(5)-en...
