NextGenMap: Fast and accurate read mapping in highly polymorphic genomes

TLDR
NextGenMap is reported, a fast and accurate read mapper, which aligns reads reliably to a reference genome even when the sequence difference between target and reference genome is large, i.e. highly polymorphic genome.
Abstract
Summary: When choosing a read mapper, one faces the trade off between speed and the ability to map reads in highly polymorphic regions. Here, we report NextGenMap, a fast and accurate read mapper, which reduces this dilemma. NextGenMap aligns reads reliably to a reference genome even when the sequence difference between target and reference genome is large, i.e. highly polymorphic genome. At the same time, NextGenMap outperforms current mapping methods with respect to runtime and to the number of correctly mapped reads. NextGenMap efficiently uses the available hardware by exploiting multi-core CPUs as well as graphic cards (GPUs), if available. In addition, NextGenMap handles automatically any read data independent of read length and sequencing technology. Availability: NextGenMap source code and documentation are available at: http://cibiv.github.io/NextGenMap/ Contact: fritz.sedlazeck@univie.ac.at Supplementary information: Supplementary data are available at Bioinformatics online.

Parthenogenetic Panagrolaimus species evolve at lower mutation rates, but show increased nucleotide diversity

TL;DR: The findings in parthenogenetic triploid nematode populations seem to challenge common expectations of evolution under asexuality, and a gene network revealed a high level of genetic differentiation among asexual strains.

An unexpected donor in the adaptive introgression candidate Helianthus annuus subsp. texanus

TL;DR: It is argued that the morphological convergence observed in Texas is likely independent of introgression, using whole genome sequencing data from across the entire range of H. annuus and possible donor species, as well as phenotypic data from a common garden study.

Unbiased discovery of natural sequence variants that influence fungal virulence

TL;DR: In this article , the authors used bulked segregant analysis and association analysis, genetic methods that require no prior knowledge of sequence function, to address the key question of which naturally occurring sequence variants influence fungal virulence.

An effective method to resolve ambiguous bisulfite-treated reads.

TL;DR: Liu et al. as mentioned in this paper proposed EM-MUL, which not only rescues multireads overlapped with unique reads, but also uses the overall coverage and accurate base-level alignment to resolve multiread that cannot be handled by current methods.

Stampy: a statistical algorithm for sensitive and fast mapping of Illumina sequence reads.

TL;DR: A read mapper, Stampy, which uses a hybrid mapping algorithm and a detailed statistical model to achieve both speed and sensitivity, particularly when reads include sequence variation, which results in a higher useable sequence yield and improved accuracy compared to that of existing software.
