Abstract

Adelanthaceae (including Jamesoniellaceae) represent a major lineage of jungermannialean liverworts that is characterized by ventral-intercalary, often flagelliform branches, succubous leaves, ovoid to cylindrical, plicate perianths with a contracted mouth, often connate bracts and bracteoles, and 4-7 stratose capsule walls. Here we present the first comprehensive molecular phylogeny of Adelanthaceae using five markers (rbcL, psbA, trnL-trnF region, atpB-rbcL spacer, nrITS1-5.8S-ITS2) and 108 accessions from throughout the geographic range of the family. The molecular data support the separation of subfamilies Adelanthoideae and Jamesonielloideae. The Adelanthoideae include the genera Adelanthus, Pseudomarsupidium and Wettsteinia. The Jamesonielloideae include representatives of the genera Anomacaulis, Cryptochila, Cuspidatula, Jamesoniella, and Syzygiella in five main clades. The monophyly of taxa in current morphological classification schemes of Jamesonielloideae is not supported by the molecular data. Based on the outcome of the molecular phylogenetic analyses we propose to include Anomacaulis and Jamesoniella kirkii in Cuspidatula, and to place Cryptochila, Roivainenia, and Jamesoniella in the synonymy of Syzygiella.

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.
