Reliable Inference of Phylogenomic Relationship via Assembly‐Based Strategy Accommodating Raw Reads and Proteins

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Phylogenomics is a transformative approach in systematics, conservation biology, and biomedical research, enabling the inference of evolutionary relationships by leveraging hundreds to thousands of genes from genomic or transcriptomic data. However, acquiring high‐quality genomes and transcriptomes necessitates samples with intact DNA and RNA,

Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

A novel birnavirus identified as the causative agent of summer atrophy of pearl oyster (Pinctada fucata (Gould)) [PDF]

PeerJ
The Akoya pearl oyster (Pinctada fucata (Gould)) is the most important species for pearl cultivation in Japan. Mass mortality of 0-year-old juvenile oysters and anomalies in adults, known as summer atrophy, have been observed in major pearl farming areas

Preliminary survey on the relationship between dimensions of pinctada radiata in Moqam

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1994
Samples of the pearl oysters pinctada radiata were collected from Moqam (Jat. 26 50 ooNand long. 53 27 ooE) on October and January 1992 and were analyzed to study the relationship among linear measurement. Simple linear regression has revealed that there

Salinity–temperature interaction drives metabolic and energetic changes in an Arctic crustacean

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract The Arctic is shifting towards a prevalence of warm and more saline Atlantic‐like waters. These changes in the marine environment pose significant challenges for the ecophysiology of marine invertebrates. Here, we measured the metabolic enzyme activity of citrate synthase and lactate dehydrogenase, as well as the energy content and level of ...

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

Advanced Functional Materials, Volume 36, Issue 17, 26 February 2026.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Association between novel EST-SNPs and commercial traits in Pinctada fucata martensii

Aquaculture Reports, 2016
To facilitate marker-assisted selection for genetic improvement of the pearl oyster Pinctada fucata martensii, two novel single nucleotide polymorphism (SNP) markers (A376C and A316C) were screened from two shell matrix genes (prismalin-14 and N19 gene),

Genomic Insights Into the Use of Green Tea (Camellia sinensis) as a Functional Feed Additive in Sustainable Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Aquaculture is the fastest‐growing sector of animal food production, yet it faces increasing challenges in maintaining fish health and sustainability due to the widespread use of antibiotics and synthetic feed additives. Green tea (Camellia sinensis), a natural source of polyphenols and bioactive compounds, has gained attention as a functional
