Abstract:
... As genotyping-by-sequencing (GBS) is widely used in barley genetic studies, the translation of the physical position of GBS-derived SNPs into accurate genetic positions has become relevant. The main aim of this study was to develop a high-resolution consensus linkage map based on GBS-derived SNPs. The construction of this integrated map involved 11 bi-parental populations composed of 3743 segregat ...

Abstract:
... BACKGROUND: Recombination maps are important resources for epidemiological and evolutionary analyses; however, there are currently no recombination maps representing any African population outside of those with West African ancestry. We infer the demographic history for the Nama, an indigenous Khoe-San population of southern Africa, and derive a novel, population-specific recombination map from th ...

Abstract:
... Tailed bacteriophages are abundant and extremely diverse. Understanding this diversity is a challenge, and here we examine a small slice of that diversity in some detail. We contrast and compare the small genome, virulent, non-contractile tailed phages that infect the bacterial order Enterobacteriales. These phages, with genomes in the 35–60 kbp range, have very similar virions that are often diff ...

Here we updated the chromosome-level genome of Takifugu bimaculatus by an ultra-high-density linkage map, a classic and accurate way of chromosome assembly. The map constituted a robust assembly frame, with 92.2% (372.77 Mb) of the draft geno ...

Abstract:
... With nearly all life on earth experiencing direct or indirect effects of human activity, there is an urgent need to understand how organisms do or do not adapt to human-induced environmental change. Domestication was an early crash into the Anthropocene for some species, and the response of animal populations to domestication selection gives us insights on how plastic responses and evolutionary ch ...

Abstract:
... Stem rust caused by Puccinia graminis f. sp. tritici is one of Ethiopia's most serious wheat diseases. Because of mutation and genetic recombination, stem rust can rapidly evolve new virulence to resistant genes. The Ethiopian highlands are well‐known hotspots for the rapid emergence and spread of new wheat stem rust races. The objective of this study was to determine the virulence diversity and s ...
