Minireview Research on photosynthetic reaction centers from 1932 to 1987

The history of research on photosynthetic reaction centers is outlined, starting with the implication of their existence through the discovery of the photosynthetic unit, as reported by R. Emerson and W. Arnold in 1932, and culminating in the crystallization and X-ray analysis of the anoxygenic bacterial reaction centers, reported by J. Deisenhofer, H. Michel, and coworkers, over the period 198...

Phylogenetic relationships among species of contracaecum Railliet & Henry, 1912 and Phocascaris Høst, 1932 (Nematoda:Ascaridoidea) based on nuclear rDNA sequence data.

Nuclear-encoded large-subunit ribosomal DNA sequences were used to infer a phylogenetic hypothesis for 17 taxa (16 nominal species) of the genera Contracaecum and Phocascaris. Phylogenetic trees based on these data have been used to assess the validity of the taxonomic distinction between these genera, which was based on the presence or absence of certain structural features, rather than on exp...

We introduce a new class of noncommutative rings-Galois orders, realized as certain subrings of invariants in skew semigroup rings, and develop their structure theory. The class of Galois orders generalizes classical orders in noncommutative rings and contains many classical objects, such as the Generalized Weyl algebras, the universal enveloping algebra of the general linear Lie algebra, assoc...

Robin Holliday 1932–2014

Robin Holliday When the founder of a field of investigation departs from our midst, there is the palpable feeling among his or her close associates that an era has come to an end. Such is the sense that the elders of the field of genetic recombination feel with the passing of Robin Holliday, whose very name is synonymous with the process. Hediedathis homeon theoutskirtsofSydney, Australia, on t...
