Thirteen new plastid genomes from mixotrophic and autotrophic species provide insights into heterotrophy evolution in Neottieae orchids


Mixotrophic species use both organic and mineral carbon sources. Some mixotrophic plants combine photosynthesis and a nutrition called mycoheterotrophy, where carbon is obtained from fungi forming mycorrhizal symbiosis with their roots. more »

Ancient DNA from a 2,500-year-old Caribbean fossil places an extinct bird (Caracara creightoni) in a phylogenetic context


Since the late Pleistocene humans have caused the extinction of species across our planet. Placing these extinct species in the tree of life with genetic data is essential to understand the ecological and evolutionary implications of these losses. more »


Cut-C: cleavage under tethered nuclease for conformational capture


Deciphering the 3D structure of the genome is essential for elucidating the regulatory mechanisms of gene expression in detail. Existing methods, such as chromosome conformation capture (3C) and Hi-C have enabled the identification of novel aspects of chromatin structure. more »

Exome sequencing of family trios from the National Birth Defects Prevention Study: Tapping into a rich resource of genetic and environmental data



The National Birth Defects Prevention Study (NBDPS) is a multisite, population‐based, case–control study of genetic and nongenetic risk factors for major structural birth defects. Eligible women had a pregnancy affected by a birth defect or a liveborn child without a birth defect between 1997 and 2011. more »


Systematic evaluation of library preparation methods and sequencing platforms for high-throughput whole genome bisulfite sequencing

Whole genome bisulfite sequencing (WGBS), with its ability to interrogate methylation status at single CpG site resolution epigenome-wide, is a powerful technique for use in molecular experiments. Here, we aim to advance strategies for accurate and efficient WGBS for application in future large-scale epidemiological studies. more »

Blastochloris tepida, sp. nov., a thermophilic species of the bacteriochlorophyll b-containing genus Blastochloris

A new taxon is created for the thermophilic purple nonsulfur bacterium previously designated as Rhodopseudomonas strain GI. Strain GI was isolated from a New Mexico (USA) hot spring microbial mat and grows optimally above 40 °C and to a maximum of 47 °C. Strain GI is a bacteriochlorophyll b-containing species of purple nonsulfur bacteria and displays a budding morphology, typical of species of the genus Blastochloris. more »

Retention of paternal DNA methylome in the developing zebrafish germline

Two waves of DNA methylation reprogramming occur during mammalian embryogenesis; during preimplantation development and during primordial germ cell (PGC) formation. However, it is currently unclear how evolutionarily conserved these processes are. more »

Targeted sequencing panel IDs Lynch syndrome in women with/at risk for endometrial cancer

A targeted next-generation sequencing panel rapidly identifies both germline and somatic Lynch syndrome pathogenic mutations in women with – or at risk for – endometrial cancer, according to findings in a prospective patient cohort. more »

Optimizing de novo genome assembly from PCR-amplified metagenomes

Metagenomics has transformed our understanding of microbial diversity across ecosystems, with recent advances enabling de novo assembly of genomes from metagenomes. These metagenome-assembled genomes are critical to provide ecological, evolutionary, and metabolic context for all the microbes and viruses yet to be cultivated… more »

Use of a Targeted Lynch Syndrome Next Generation Sequencing Panel in Women at Risk for or With Endometrial Cancer [32M]

Women with endometrial cancer should be screened for Lynch syndrome (LS), a hereditary cancer syndrome caused by germline mutations in DNA mismatch repair (MMR) genes. This information directly affects immediate clinical management including future risk reducing/surveillance strategies for patients and at-risk family members. It is currently unclear how best to provide molecular screening… more »

Robust single-cell DNA methylome profiling with snmC-seq2

Single-cell DNA methylome profiling has enabled the study of epigenomic heterogeneity in complex tissues and during cellular reprogramming. However, broader applications of the method have been impeded by the modest quality of sequencing libraries. more »

Corrupted coordination of epigenetic modifications leads to diverging chromatin states and transcriptional heterogeneity in CLL
