Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

Advanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Genetic population structure of the critically endangered stellate sturgeon (Acipenser stellatus) in the Black Sea basin: Implications for conservation

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1926-1939, December 2022., 2022
Abstract Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced a dramatic decline in abundance and distribution in the Black Sea basin. Information regarding the genetic structure of the species is very limited in the region, despite its crucial importance for ...

A general species delimitation method with applications to phylogenetic placements

Bioinform., 2013
Motivation: Sequence-based methods to delimit species are central to DNA taxonomy, microbial community surveys and DNA metabarcoding studies. Current approaches either rely on simple sequence similarity thresholds (OTU-picking) or on complex and compute ...

Phylogenetic lineages in the Capnodiales

Studies in Mycology, 2009
The Capnodiales incorporates plant and human pathogens, endophytes, saprobes and epiphytes, with a wide range of nutritional modes. Several species are lichenised, or occur as parasites on fungi, or animals. The aim of the present study was to use DNA sequence data of the nuclear ribosomal small and large subunit RNA genes to test the monophyly of the ...

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

Suitability of Natura 2000 sites for threatened freshwater species under projected climate change

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1872-1887, December 2022., 2022
Abstract As part of the world's largest coordinated network of protected areas, Natura 2000, European Union member states designate special areas of conservation (SACs) to maintain or achieve favourable conservation status for imperilled aquatic species listed under Annex II of the Habitats Directive.

The complete chloroplast genome of Aphelandra knappiae (Acanthaceae)

Mitochondrial DNA. Part B. Resources, 2019
Aphelandra knappiae is an important plant from the family Acanthaceae. The complete chloroplast genome of the genus Aphelandra was sequenced for the first time. The plastome of A. knappiae was 152,457 bp in length.

Magnetite Micro/Nanorobots for Efficient Targeted Alleviation of Inflammatory Bowel Disease

Advanced Science, EarlyView.
Improved reactive oxygen species scavenging capacities of functionalized micro/nanorobots (MNRs) are useful for the treatment of inflammatory bowel disease (IBD). MNRs can break the harmful bacteria in IBD, thereby eliminating inflammation and restoring the intestinal barrier function.

A computed tomography‐based survey of paramedullary diverticula in extant Aves

The Anatomical Record, Volume 306, Issue 1, Page 29-50, January 2023., 2023
Abstract Avian respiratory systems are comprised of rigid lungs connected to a hierarchically organized network of large, regional air sacs, and small diverticula that branch from them. Paramedullary diverticula are those that rest in contact with the spinal cord, and frequently invade the vertebral canal.
