Genetic diversity in a crop metapopulation [PDF]
Heredity, 2009 The need to protect crop genetic resources has sparked a growing interest in the genetic diversity maintained in traditional farming systems worldwide. Although traditional seed management has been proposed as an important determinant of genetic diversity and structure in crops, no models exist that can adequately describe the genetic effects of seed ...

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum
FEBS Letters, EarlyView.In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

A view of Neandertal genetic diversity
Nature Genetics, 2000 In order to further study of the Neandertal mtDNA gene pool, we analyzed the amino acid composition and extent of amino acid racemization in 15 bones found in the Vindija Cave (Croatia). Seven samples proved to have a high content of amino acids, an amino acid composition similar to that of the contemporary bone, and a low level of racemization of ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]
, 2013 To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Genetic diversity of local cattle*
Acta Biochimica Polonica, 2018 The Slovak Pinzgau breed faces the bottleneck effect and the loss of diversity due to unequal use of founders and significant population decline. Further population size reduction can lead to serious problems. High-throughput genotypes of 179 individuals were used to characterise genetic diversity and differentiation of Slovak Pinzgau, Austrian Pinzgau,

Evolution and genetic diversity of Theileria [PDF]
Infection, Genetics and Evolution, 2014 Theileria parasites infect a wide range of domestic and wild ruminants worldwide, causing diseases with varying degrees of severity. A broad classification, based on the parasite's ability to transform the leukocytes of host animals, divides Theileria into two groups, consisting of transforming and non-transforming species.

FEBS Letters, EarlyView.Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14

Diversity of citron (Citrus medica) and phylogenetic analysis of related citron hybrids using molecular markers and essential oil composition [PDF]
, 2015 Citrus diversity is known to be essentially supported by three essential basic species, mandarin, pummelo and citron, which are at the origin of quite all the cultivated citrus.
