Schistosoma mansoni has a diploid genome of approximately 380 MB, organized in 7 pairs of autosomes and 2 sex chromosomes. The original Schistosoma mansoni Genome Project was completed by the Wellcome Sanger Institute in collaboration with The Institute for Genome Research using a Whole Genome Shotgun sequencing strategy. The draft assembly was subsequently improved first by incorporating Illumina reads from a clonal (single-miracidial) infection and more recently by incorporating long PacBio reads, HiC, and optical mapping data.

The synthesis of the only unknown 1,2:5,6-di-O-isopropylidene-D-hexose, D-mannose, is reported. Its preparation involved the stereospecific borohydride reduction of the 3-keto intermediate prepared from D-altrose. An improved synthesis of the known D-talose derivative proceeded in an analogous manner from the parent ketone. The four 3-keto derivatives of the diacetone D-hexoses were prepared and their properties compared. In an attempt to explain the differences found in the ease of hydration of these materials, high resolution infrared hydrogen bonding studies were carried out on the eight hexose derivatives and the one hydrated ketone.

Abstract The reed warbler ( Acrocephalus scirpaceus ) is a long-distance migrant passerine with a wide distribution across Eurasia. This species has fascinated researchers for decades, especially its role as host of a brood parasite, and its capacity for rapid phenotypic change in the face of climate change. Currently, it is expanding its range northwards in Europe, and is altering its migratory behaviour in certain areas. Thus, there is great potential to discover signs of recent evolution and its impact on the genomic composition of the reed warbler. Here we present a high-quality reference genome for the reed warbler, based on PacBio, 10X and Hi-C sequencing. The genome has an assembly size of 1,075,083,815 bp with a scaffold N50 of 74,438,198 bp and a contig N50 of 12,742,779 bp. BUSCO analysis using aves_odb10 as a model showed that 95.7% of genes in the assembly were complete. We found unequivocal evidence of two separate macrochromosomal fusions in the reed warbler genome, in addition to the previously identified fusion between chromosome Z and a part of chromosome 4A in the Sylvioidea superfamily. We annotated 14,645 protein-coding genes, of which 97.5% were complete BUSCO orthologs. This reference genome will serve as an important resource, and will provide new insights into the genomic effects of evolutionary drivers such as coevolution, range expansion, and adaptations to climate change, as well as chromosomal rearrangements in birds. Significance statement The reed warbler ( Acrocephalus scirpaceus ) has been lacking a genomic resource, despite having been broadly researched in studies of coevolution, ecology and adaptations to climate change. Here, we generated a chromosome-length genome assembly of the reed warbler, and found evidence of macrochromosomal fusions in its genome, which are likely of recent origin. This genome will provide the opportunity for a deeper understanding of the evolution of genomes in birds, as well as the evolutionary path and possible future of the reed warbler.
We present a genome assembly from an individual female Anopheles gambiae (the malaria mosquito; Arthropoda; Insecta; Diptera; Culicidae), Ifakara strain. The genome sequence is 264 megabases in span. Most of the assembly is scaffolded into three chromosomal pseudomolecules with the X sex chromosome assembled. The complete mitochondrial genome was also assembled and is 15.4 kilobases in length.
Abstract Caesium N.M.R. spectra of the caesium ion have been measured in a nematic lyotropic liquid-crystalline solution prepared from caesium decylsulphate/decanol/water. The contributions of an asymmetry parameter, a second order quadrupole coupling and a hexadecapole coupling to the spectra have been discussed. The N.M.R. spectra was shown to be consistent with the occurrence of a hexadecapole interaction in the quadrupole split spectrum. The ratio = 1:0.0000034 was obtained.
