Understanding how recombination rates vary between genetically differentiated populations of the same species is an important step toward disentangling the role of recombination in genetic differentiation.. within the range of recombination rates measured for other suporrosids (Table 1. an expected result in the pres- ence of recombination hotspots.

Genome-wide patterns of differentiation within and among U.S. commercial honey bee stocks

This provides further evidence of the genetic differentiation of Hilo and Pol-line from other stocks. This may indicate a greater contribution of the Pol-line ancestry to Hilo, with F ST estimates suggesting that Hilo is more differentiated from the combined Italian. Csd exons are depicted across the base of the figure.

Comparative population genomics reveals genetic divergence and selection in lotus, Nelumbo nucifera

tailieu.vn

Based on the NJ tree and PCA results, rhizome lotus shows high genetic differentiation from seed lotus and flower lotus. Hence, the possibility that rhizome lotus was domesticated independently from different populations of flower lotus and seed lotus was considered. To further analyze the domestication history of lotus, we constructed a multilevel (K = 2, 3…7) population structure to estimate the maximum likelihood ancestry and the proportion of the ancestral property in each individual (Fig.

Identification of genetic loci and candidate genes related to soybean flowering through genome wide association study

It was found that the average LD decay distance of the population was about 300 kb (r 2 = 0.5) by 34,710 SNP markers for LD ana- lysis (Fig. a Distribution of the SNP markers across 20 soybean chromosomes. shaping genetic differentiation of soybean. The total of 223 SNP loci associated with flowering time, full bloom, beginning pod, full pod, beginning seed, and full seed in one or more environments were all considered to be candidate sites for flowering time in soybean, because.

Influence of genetic diversity of seventeen Beauveria bassiana isolates from different hosts on virulence by comparative genomics

tailieu.vn

Furthermore, in the PCA plot, an obvious separation of three clusters was found, which also revealed a clear genetic differentiation among these 17 samples.. In previous study, genes with a signature of positive selection is possible to result in the adaptation to a dy- namic environment and may be associated with fungi virulence [18]. Herein, we calculated the Ka/Ks values to identify the genes subjected to selection in the evolution of B.

Genomic diversity in pearl millet inbred lines derived from landraces and improved varieties

tailieu.vn

In pearl millet, genetic differentiation is important in the genetic im- provement of the crop for productivity and adaptation in the agriculturally marginal environments.

Population structure of Apodemus flavicollis and comparison to Apodemus sylvaticus in northern Poland based on RAD-seq

tailieu.vn

Our data present clear genetic divergence of the two species, with average p-distance, based on 21377 common loci, of 1.51% and a mutation rate of substitutions per site per million years. We provide a catalogue of 117 highly divergent loci that enable genetic differentiation of the two species in Poland and to a large degree of 20 unrelated samples from several European countries and Tunisia.

Genomic analysis of worldwide sheep breeds reveals PDGFD as a major target of fat-tail selection in sheep

tailieu.vn

We demonstrated that PDGFD gene locus, with known involvement in adipogen- esis [12, 13], exhibited the highest genetic differentiation between fat- and thin-tailed sheep and further found that the potential causal mutations are located within regula- tory region.

The patterns of admixture, divergence, and ancestry of African cattle populations determined from genome-wide SNP data

tailieu.vn

Breed differentiation, as represented by F ST values, showed a strong divergence within different groups of breeds (European Bos taurus , African Bos taurus , zebu types, Sanga types including admixed breeds, and Bos indicus . Ranked from lowest to highest genetic differentiation between breeds within groups are zebu types, Bos indicus , Sanga types, African Bos taurus, and lastly, European Bos taurus .

Genetic structure of the durum wheat collection. All but one (BGE021775) of the 14 accessions belonging to subsp. dicoccon were grouped in Pop5, and all 37 of the subsp. All of the 140 subsp. Pop6 showed the least genetic differentiation from the rest of the populations, including those of subsp.

Genetic diversity analysis of a flax (Linum usitatissimum L.) global collection

tailieu.vn

The negative correlation between diversity indices (H and I) and relatedness indicates that inbreeding and genetic drift play a significant role in reducing genetic vari- ability in the studied population which results in increased differentiation among sub-populations.

Diploid genome differentiation conferred by RNA sequencing-based survey of genome-wide polymorphisms throughout homoeologous loci in Triticum and Aegilops

tailieu.vn

Background: Triticum and Aegilops diploid species have morphological and genetic diversity and are crucial genetic resources for wheat breeding. However, evaluations of genome differentiation based on genome- wide nucleotide variations are still limited, especially in the three genomes of the genus Aegilops: Ae.. (MM genome), and Ae.

Genetic diversity among cultivated beets (Beta vulgaris) assessed via populationbased whole genome sequences

tailieu.vn

Beet crop types are important lineages which exhibit both genetic and phenotypic divergence. It would appear selection for end use qualities and genetic drift were major factor in the observed differentiation be- tween lineages and explains the apportionment of genetic variation between crop types at distinct chromosome loca- tions.

TMT-based quantitative proteomics analysis reveals the key proteins related with the differentiation process of goat intramuscular adipocytes

tailieu.vn

SERPINE1 has been reported to be related to adipocyte differentiation, and inhibition of the SERPINE1 in 3T3-L1 adipocytes can increase the ex- pression of PPARγ, promote adipocyte differentiation, and decrease insulin resistance [52, 53]. And the role of CSRP3 and SRSF10 were shown in above discussion.
