The introduction of Juglans species (Juglandaceae) in Ukraine
The results of investigation of the nuts plantations in Ukraine in 1996–1998 are presented. The tendency to deminution of the range of introduction of the genus Juglans L. is showed.

Structural and biochemical analysis of a B12 superbinder
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

The EU phytosanitary system and invasive alien species
The phytosanitary provisions and systems of the European Union (EU) and its member states have been fully harmonized since 1993. They are in place to minimize the introduction of alien organisms that are harmful to plants and plant products and to limit ...

Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Risks posed by the spread and dissemination of grapevine pathogens and their vectors
Several diseases of grapevine are transmissible by grafting as well as by aerial vectors. Risks of spread and dissemination of these diseases evolve from the potential introduction of the associated pathogens into new areas, and from the vectors ...
