Decoding the genome of bloodsucking midge Forcipomyia taiwana (Diptera: Ceratopogonidae): Insights into odorant receptor expansion.

Biting midges, notably those within the Ceratopogonidae family, have long been recognized for their epidemiological significance, both as nuisances and vectors for disease transmission in vertebrates. Despite their impact, genomic insights into these insects, particularly beyond the Culicoides genus, remain limited. In this study, we assembled the Forcipomyia taiwana (Shiraki) genome, comprising 113 scaffolds covering 130.

phiC31 integrase for recombination-mediated single-copy insertion and genome manipulation in Caenorhabditis elegans.

Caenorhabditis elegans benefits from a large set of tools for genome manipulation. Yet, the precise single-copy insertion of very large DNA constructs (>10 kb) and the generation of inversions are still challenging. Here, we adapted the phiC31 integrase system for C.

Chromosomal-level genome assembly of the semi-dwarf rice Taichung Native 1, an initiator of Green Revolution.

Here we report the 409.5 Mb chromosome-level assembly of the first bred semi-dwarf rice, the Taichung Native 1 (TN1), which served as the template for the development of the Green Revolution (GR) cultivar IR8 "miracle rice". We sequenced the TN1 genome utilizing multiple platforms and produced PacBio long reads, Illumina paired-end reads, Illumina mate-pair reads and 10x Genomics linked reads.

Whole-Genome Sequence Resource of , the Casual Pathogen of Soybean Red Crown Rot.

(anamorph: ) is a soilborne plant-pathogenic fungus with a broad host range, and it can cause red crown rot of soybean and Cylindrocladium black rot of peanut, which has become an emerging threat to crop production worldwide. Limited molecular studies have focused on and one of the possible difficulties is the lack of genomic resources. This study presents the first high quality and near-completed genome of , using the Oxford Nanopore GridION sequencing platform.

genomes resolve the evolution of fungal bioluminescence.

Mushroom-forming fungi in the order Agaricales represent an independent origin of bioluminescence in the tree of life; yet the diversity, evolutionary history, and timing of the origin of fungal luciferases remain elusive. We sequenced the genomes and transcriptomes of five bonnet mushroom species ( spp.), a diverse lineage comprising the majority of bioluminescent fungi.

Blast Fungal Genomes Show Frequent Chromosomal Changes, Gene Gains and Losses, and Effector Gene Turnover.

Pyricularia is a fungal genus comprising several pathogenic species causing the blast disease in monocots. Pyricularia oryzae, the best-known species, infects rice, wheat, finger millet, and other crops. As past comparative and population genomics studies mainly focused on isolates of P.

Co-opting sulphur-carrier proteins from primary metabolic pathways for 2-thiosugar biosynthesis.

Sulphur is an essential element for life and is ubiquitous in living systems. Yet how the sulphur atom is incorporated into many sulphur-containing secondary metabolites is poorly understood. For bond formation between carbon and sulphur in primary metabolites, the major ionic sulphur sources are the persulphide and thiocarboxylate groups on sulphur-carrier (donor) proteins.

Functional characterization of the agtABCD and agtSR operons for 4-aminobutyrate and 5-aminovalerate uptake and regulation in Pseudomonas aeruginosa PAO1.

Growth of Pseudomonas aeruginosa on diamines cadaverine, putrescine, and diaminopropane requires the γ-glutamylation pathway to convert these diamines into δ-aminovalerate (AMV), γ-aminobutyrate (GABA), and β-alanine. From DNA microarrays experiments the agtABCD operon (PA0603-0606) encoding components for an ABC transporter system was found inducible by exogenous AMV, GABA, and β-alanine, but not by diamines. Induction of the agtABCD operon was abolished in the mutants of upstream agtS (PA0600) or agtR (PA0601) genes encoding the membrane-anchored sensor and the response regulator of a two-component regulatory system, respectively.

Molecular characterization of PauR and its role in control of putrescine and cadaverine catabolism through the γ-glutamylation pathway in Pseudomonas aeruginosa PAO1.

Pseudomonas aeruginosa PAO1 grows on a variety of polyamines as the sole source of carbon and nitrogen. Catabolism of polyamines is mediated by the γ-glutamylation pathway, which is complicated by the existence of multiple homologous enzymes with redundant specificities toward different polyamines for a more diverse metabolic capacity in this organism. Through a series of markerless gene knockout mutants and complementation tests, specific combinations of pauABCD (polyamine utilization) genes were deciphered for catabolism of different polyamines.

Functional characterization of cellulases identified from the cow rumen fungus Neocallimastix patriciarum W5 by transcriptomic and secretomic analyses.

Background: Neocallimastix patriciarum is one of the common anaerobic fungi in the digestive tracts of ruminants that can actively digest cellulosic materials, and its cellulases have great potential for hydrolyzing cellulosic feedstocks. Due to the difficulty in culture and lack of a genome database, it is not easy to gain a global understanding of the glycosyl hydrolases (GHs) produced by this anaerobic fungus.

Results: We have developed an efficient platform that uses a combination of transcriptomic and proteomic approaches to N.

Severe acute respiratory syndrome coronavirus 3C-like protease-induced apoptosis.

The pathogenesis of severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is an important issue for the treatment and prevention of severe acute respiratory syndrome. Recently, SARS-CoV has been demonstrated to induce cell apoptosis in Vero-E6 cells. The possible role of SARS-CoV 3C-like protease (3CLpro) in virus-induced apoptosis is characterized in this study.

Binding interaction of SARS coronavirus 3CL(pro) protease with vacuolar-H+ ATPase G1 subunit.

The pathogenesis of severe acute respiratory syndrome coronavirus (SARS-CoV) is an important issue for treatment and prevention of SARS. Recently, SARS-CoV 3CL(pro) protease has been implied to be possible relevance to SARS-CoV pathogenesis. In this study, we intended to identify potential 3CL(pro)-interacting cellular protein(s) using the phage-displayed human lung cDNA library.
