A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Genetics and Population History of Caucasus Populations

Human Biology, 2003
We describe aspects of genetic diversity in several ethnic populations of the Caucasus Mountains of Daghestan using mitochondrial DNA sequences and a sample of 100 polymorphic Alu insertion loci. The mitochondrial DNA (mtDNA) sequences are like those of Europe.

Reconstructing the population history of the Nicobarese

European Journal of Human Genetics
The Nicobarese are the major tribal groups in the Nicobar district, situated south of the Andaman group of Islands. Linguistic phylogeny suggests that the linguistic ancestors of the Nicobarese settled the Nicobar archipelago in the early Holocene. So far, genetic research on them is low-resolution and restricted to the haploid DNA markers.

History and the Limits of Population Policy

Politics & Society, 1980
A detailed case study of the fertility decline in the United States between 1855 and 1915 is summarized. Included in the data base are about 30000 families 1 of the largest data bases ever compiled for the historical study of fertility. Focus in this discussion is on the major trends in the data and what they convey regarding the interconnections ...

Evolutionary History and Population Biology

Nature, 1967
While accepting evolutionary theory, should ecologists be more sceptical about hypotheses derived solely from untestable assumptions about the past ? The authors put forward the view that many ecologists underestimate the efficacy of natural selection and fail to distinguish between phylogenetic and ecological questions.

History of Plant Population Genetics

Annual Review of Genetics, 1999
▪ Abstract  This review of plant population genetics focuses on the genetic foundations of the processes that have led to documentable improvements in cultivated plants since the earliest domestications took place perhaps 13,000 years ago. Nearly all human civilizations have depended heavily on inbreeding plants (particularly wheat, barley, soybeans ...

Genetic history of the population of Sicily.

Human biology, 1998
We investigated the genetic heterogeneity of 2354 individuals from the 9 provinces of Sicily. The genetic markers we used were HP, GC, TF, PI, and AK1 plus other previously tested polymorphisms, for a total of 24 independent markers. Distinct multivariate statistics were applied to verify the claimed genetic distinctiveness between extant eastern and ...
