Complete genome sequence of a new member of the genus Badnavirus infecting nettle (Urtica dioica).

A new badnavirus was discovered in nettle plants (Urtica dioica L., family Urticaceae) with vein banding symptoms using high-throughput sequencing. This virus was provisionally named "nettle badnavirus 1" (NBV 1).

Chemical Resolution of an Epitope Recognized by Blood Group Antibodies Capable of Binding Both A and B Red Blood Cells.

The high specificity of human antibodies to blood group A and B antigens is impressive, especially when considering the structural difference between these antigens (tetrasaccharides) is a NHAc versus a hydroxyl group on the terminal monosaccharide residue. It is well established that in addition to anti-A and anti-B there is a third antibody, anti-A,B capable of recognizing both A and B antigens. To analyze this AB specificity, we synthesized a tetrasaccharide, where the NHAc of the A antigen was replaced with an NH.

Koban culture genome-wide and archeological data open the bridge between Bronze and Iron Ages in the North Caucasus.

The North Caucasus played a key role during the ancient colonization of Eurasia and the formation of its cultural and genetic ancestry. Previous archeogenetic studies described a relative genetic and cultural continuity of ancient Caucasus societies, since the Eneolithic period. The Koban culture, which formed in the Late Bronze Age on the North Caucasian highlands, is considered as a cultural "bridge" between the ancient and modern autochthonous peoples of the Caucasus.

genes from pKM101 and from chromosome have a different range of regulated genes.

The genes are present in a wide variety of conjugative plasmids and play an important role in overcoming the restriction barrier. To date, there is no information on the chromosomal genes. It is still unclear whether they keep their antirestriction activity and why bacterial chromosomes contain these genes.

First Report and Complete Genome Characterization of Cherry Virus A and Little Cherry Virus 1 from Russia.

Virus diseases affect the yield and fruit quality and shorten the productive life of stone fruits ( spp. in the family ). Of over fifty known viruses infecting these crops, cherry virus A (CVA) is among the most common, and little cherry virus 1 (LChV1) is one of the most economically important.
