Prenatal Screening Via cfDNA – Paired‐End Sequencing Utilizing Fragment Size Information Reduces the Screen Positive Rate for X Chromosome Aneuploidies

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective Prenatal cfDNA screening has transformed care, yet it remains difficult to determine whether X aneuploidy signals originate from the patient or fetus, inflating screen positive and false positive rates. One potential solution is to incorporate fragment size data from paired‐end sequencing (PES).

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Effect of Ploidy in Photoreactivation.

open access: yesExperimental Biology and Medicine, 1952
SummaryThe survival fractions of diploid and haploid strains of S. cerevisiae after ultraviolet irradiation (2537 A.U.) have been obtained, compared, and modified by photoreactivation following the initial irradiation. The haploid survival follows a sigmoid curve and is smaller than the diploid at the same dose.

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Fluconazole-Induced Ploidy Change in Cryptococcus neoformans Results from the Uncoupling of Cell Growth and Nuclear Division

open access: yesmSphere, 2017
Cryptococcus neoformans is a pathogenic yeast that causes lethal cryptococcal meningitis in immunocompromised patients. One of the challenges in treating cryptococcosis is the development of resistance to azole antifungals.

Comparative analysis of cell-free DNA content in culture medium and mitochondrial DNA copy number in porcine parthenogenetically activated embryos

open access: yesThe Journal of Reproduction and Development, 2020
We examined the effect of ploidy on mitochondrial DNA (mtDNA) copy number in embryos and the amount of cell-free mitochondrial and nucleic DNA content (cf-mtDNA and cf-nDNA) in spent culture medium (SCM).

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Impact of plant breeding on the responsiveness of maize and wheat varieties to an arbuscular mycorrhizal fungal symbiont

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Field inoculation with arbuscular mycorrhizal fungi (AMF) offers a promising route to improve sustainable agriculture and food production, yet results are often variable. We investigated the mycorrhizal growth response of maize and wheat varieties recommended for farmers and found substantial variation under greenhouse conditions.

Genome Size in the Arenaria ciliata Species Complex (Caryophyllaceae), with Special Focus on Northern Europe and the Arctic

open access: yesPlants
The main aim of the present study has been the completion of genome size data for the diverse arctic-alpine A. ciliata species complex, with special focus on the unexplored arctic taxon A. pseudofrigida, the north-European A. norvegica, and A.
