Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

Insect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.

Genome sizes and karyotypes in the razor clams "Ensis arcuatus" (Jeffreys, 1865) and "E. siliqua" (Linnaeus, 1758) [PDF]

, 2008
[Abstract] The razor clams Ensis arcuatus and E. siliqua show a diploid DNA content of 3.85 ± 0.049 pg and 4.00 ± 0.050 pg, respectively. Both have a diploid chromosome number of 38 although their karyotypes show remarkable differences.

Liquid–Liquid Phase Separation in Major Hallmarks of Cancer

Cell Proliferation, EarlyView.
Aberrant condensates formed through phase separation are involved in the dysregulation of various critical cellular processes, including genome stability, transcriptional regulation and signal transduction, thereby promoting malignant transformation and the acquisition of multiple cancer hallmarks.

Chicken rRNA Gene Cluster Structure. [PDF]

PLoS ONE, 2016
Ribosomal RNA (rRNA) genes, whose activity results in nucleolus formation, constitute an extremely important part of genome. Despite the extensive exploration into avian genomes, no complete description of avian rRNA gene primary structure has been ...

Benthoplanidae, a new family of benthic ctenophores (Platyctenida), based on morphological and genetic data

Journal of Systematics and Evolution, EarlyView.
The benthic ctenophore Benthoplana meteoris (adults left and bottom, planktonic juveniles to the top right), type species for the genus, which in turn is type for the newly erected family: Benthoplanidae (Ctenophora, Platyctenida). Abstract We present a phylogenetic analysis of benthic ctenophores of the order Platyctenida, sampling all but one genus ...

Reduced ribosomal RNA expression and unchanged ribosomal DNA promoter methylation in oral squamous cell carcinoma

Molecular Genetics & Genomic Medicine, 2019
Background Ribosomal RNA (rRNA) consists of four non‐coding RNAs, the 28S, 5.8S, 18S, and 5S rRNA. Abnormal expression of rRNA has been found in multiple tumors, and the methylation of rDNA promoter may affect rRNA expression as an epigenetic regulatory ...

A new species of Semisulcospira O. Boettger, 1886 (Gastropoda, Cerithoidea, Semisulcospiridae) from Fujian, China with mitochondrial genome and its phylogenetic implications [PDF]

Zoosystematics and Evolution
During our investigation of the diversity and phylogeny of the family Semisulcospiridae in China, we have found a presumed new species in mountain streams of Xiamen, Fujian Province on both morphology and molecular evidence.

Testing robustness of relative complexity measure method constructing robust phylogenetic trees for Galanthus L. Using the relative complexity measure [PDF]

, 2013
Background: Most phylogeny analysis methods based on molecular sequences use multiple alignment where the quality of the alignment, which is dependent on the alignment parameters, determines the accuracy of the resulting trees.

Whole genome sequencing of historical specimens from the world's largest fungal collection yields high‐quality assemblies

New Phytologist, EarlyView.
Summary High‐throughput molecular studies of museum specimens (museomics) have great potential in biodiversity research, but fungal historical collections have scarcely been examined, leading to no comprehensive methodological assessments. Here we present a whole genome sequencing (WGS) project conducted at the Fungarium of the Royal Botanic Gardens ...
