Russian thistle or tumbleweed (Salsola tragus L.) is an introduced invasive weed in N. America. It is widely distributed in the U.S. and is a target of biological control efforts. The obligate biotrophic rust fungus Uromyces salsolae Reichardt is a candidate biological control agent of Russian thistle, and host range tests were conducted in quarantine to determine whether the fungus is safe to ...

This paper is intended to shed light on the extent of poverty in the Russian Federation. We present estimates of poverty lines and poverty ratios derived from subjective questions used in a during data collection for a large household panel (RUSSET). We estimate poverty using a subjective approach, where the level of the poverty line is derived using the opinion of the individual, rich or poor,...

Health care is receiving much higher priority and more funds than ever before in the Russian Federation. Russian health economist Igor Sheiman talks to Fiona Fleck.

The genus Amaranthus contains 44 species and belongs to the family of Amaranthaceae classified within the order of Caryophyllales. Within this order a number of allergenic species including Amaranthus retroflexus (Redroot pigweed), Beta vulgaris (sugar beet), Chenopodium album (Lambsquaters), Kochia scoparia (Burning bush), and Salsola kali (Russian thistle) have been acknowledged by the WHO/IU...

Marketed plants are an important but a vulnerable group of plants whose investigations as well as conservation should be considered with priority. The chemistry, and in some cases biological activities of novel iso ̄avonoids, nor-lignans, anthracene and naphthalene derivatives and poly prenylated ̄avonoids isolated and characterized from Hagenia abyssinica, Salsola somalensis, Hypoxis spp., Tave...

Serratia marcescens is a frequent cause of health care-associated infections and has led to multiple outbreaks. Here, we report the draft genome of a multidrug-resistant S. marcescens strain 189 which was isolated in 2012 as a predominant clone in a neonatal hospital in Kemerovo.

Molecular information suggests that Russian thistle (Salsola tragus L.) in the US may consist of more than one genetic entity. This genetic variation needs to be taken into account when developing agents for biological control of this important weed. Preliminary evidence suggests that there are differences in susceptibility of Salsola sp. to infection by fungal pathogens. In the present study, ...
