The curious case of the disappearing piRNAs

open access: yesWIREs RNA, Volume 15, Issue 2, March/April 2024.
piRNAdise lost: piRNAs, a key component of the defense against transposable elements appeared very early in animal evolution. Remarkably however, they have been lost multiple times independently in different lineages (schematically indicated by pale blue dots), and as yet no clear explanation has been uncovered.

Pest risk assessment of Leucinodes orbonalis for the European Union

open access: yesEFSA Journal, Volume 22, Issue 3, March 2024.
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment of Leucinodes orbonalis (Lepidoptera: Crambidae), the eggplant fruit and shoot borer, for the EU. The assessment focused on potential pathways for entry, climatic conditions favouring establishment, spread and impact ...

Biodiversity of Nematodes from Coral Reef Sediments in the South China Sea Based on eDNA Metabarcoding

open access: yesDiversity
Coral reef ecosystems in the South China Sea are one of the globally important marine biodiversity hotspots. However, there are few studies on nematode biodiversity in coral reef sediments.

What is the meta‐analytic evidence for life‐history trade‐offs at the genetic level?

open access: yesEcology Letters, Volume 27, Issue 1, January 2024.
Negative genetic correlations are predicted to underpin trade‐offs among life‐history traits. Here we synthesize the current literature and find contrary to theoretical assumptions, there is little meta‐analytic evidence for negative genetic correlations; rather there appears to be weak evidence of positive correlations between survival and other ...

DAF-16/FoxO directly regulates an atypical AMP-activated protein kinase gamma isoform to mediate the effects of insulin/IGF-1 signaling on aging in Caenorhabditis elegans.

open access: yesPLoS Genetics, 2014
The DAF-16/FoxO transcription factor controls growth, metabolism and aging in Caenorhabditis elegans. The large number of genes that it regulates has been an obstacle to understanding its function.

Redescription and molecular characterisation of nematode Aprocta turgida Stossich, 1902 (Chromadorea: Aproctoidea: Aproctidae), parasite of larid birds

open access: yesJournal of Natural History
Adult females and males of aproctid nematode Aprocta turgida were collected from the nasal cavity of Larus cachinnans Pallas, 1811 obtained in Dagestan, Russia. Parasites were examined using light and scanning electron microscopy, and genetically characterised based on partial sequences of 18S rRNA and cox1 genes. This study of A. turgida enabled us to

Additional file 1: of The complete mitochondrial genome of parasitic nematode Camallanus cotti: extreme discontinuity in the rate of mitogenomic architecture evolution within the Chromadorea class

open access: yes, 2017
Taxonomic identification of the studied C. cotti nematode using cox1 barcoding. Maximum likelihood analysis was conducted on 100 Camallanidae cox1 sequences, with GenBank accession numbers shown in the figure. The clade containing the queried sequence (‘Camallanus cotti this study’) is shaded purple. (PDF 40 kb)

Additional file 3: of The complete mitochondrial genome of parasitic nematode Camallanus cotti: extreme discontinuity in the rate of mitogenomic architecture evolution within the Chromadorea class

open access: yes, 2017
Mitogenomic gene order rearrangements in the Camallanina suborder. (A). A hypothetical outline of gene order rearrangements between Camallanus cotti and ancestral node A1. Ancestral node A1 is shown in Fig. 1. Genes and mitogenome fragments presumed to have undergone rearrangements are highlighted by different colours.
