Abstract

Evolutionary developmental biology examines how changes in developmental programmes give rise to developmental and, ultimately, morphological novelty. To this end, comparisons of related but distinct organisms have to be performed. The diplogastrid nematode Pristionchus pacificus has been developed as a satellite system for a detailed comparison of various developmental processes to the model organism Caenorhabditis elegans, a rhabditid nematode. In addition to developmental and genetic studies, a genomic platform has been established to analyse the biology of this organism. However, only little is known about where and how Pristionchus pacificus and its relatives live in the wild. Here we show that nematodes of the genus Pristionchus live in close association with scarabaeoid beetles and the Colorado potato beetle. In total, we generated 371 isogenic female lines from 4242 beetles collected at 25 sampling sites all over Europe. Isogenic female lines were subjected to sequence analysis and mating experiments for species determination. The 371 isolates fell into six species. Two hermaphroditic species account for about 60% of the collected nematodes. We found Pristionchus maupasi almost exclusively on cockchafers and Pristionchu...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
