How diverse is the genus Wolbachia? Multiple-gene sequencing reveals a putatively new Wolbachia supergroup recovered from spider mites (Acari: Tetranychidae).

At least 20% of all arthropods and a few nematode species are contaminated with intracellular micro organism of the genus Wolbachia. This extremely diverse genus has been subdivided into eight “supergroups” (A to H) on the foundation of nucleotide sequence information. Here, we report the discovery of a new Wolbachia supergroup recovered from the spider … Read more

Cloning and nucleotide sequencing of the bovine growth hormone gene.

The pbpB gene, which encodes penicillin-binding protein (PBP) 2B of Bacillus subtilis, has been cloned, sequenced, mapped, and mutagenized. The sequence of PBP 2B locations it amongst the class B high-molecular-weight PBPs. It seems to comprise three useful domains: an N-terminal area homologous to the corresponding area of different class B PBPs, a penicillin-binding area, … Read more
