Elemental analyses reveal distinct mineralization patterns in radular teeth of various molluscan taxa [PDF]

Scientific Reports, 2022
The molluscan phylum is the second specious animal group with its taxa feeding on a variety of food sources. This is enabled by the radula, a chitinous membrane with embedded teeth, one important autapomorphy.

The complete mitochondrial genome and phylogenetic analysis of Lepidozona coreanica (Reeve, 1847) [PDF]

Mitochondrial DNA. Part B. Resources, 2023
In the present study, the complete mitochondrial genome of Lepidozona coreanica was sequenced and described. The complete mitogenome sequence of L. coreanica is 16,572 bp long and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and

A Chromosome-Level Genome Assembly of Chiton Acanthochiton rubrolineatus (Chitonida, Polyplacophora, Mollusca) [PDF]

Animals
(1) Background: Chitons (Mollusca, Polyplacophora) are relatively primitive species in Mollusca that allow the study of biomineralization. Although mitochondrial genomes have been isolated from Polyplacophora, there is no genomic information at the ...

Evaluating Probe Design for Phylogenomics Across Taxonomic Scales: First Steps for Applying Ultraconserved Elements in an Understudied Class (Mollusca: Polyplacophora). [PDF]

Mol Ecol Resour
ABSTRACT Ultraconserved elements (UCEs) have become a powerful tool for phylogenomics, but probe sets optimized for one lineage often perform inconsistently when applied in others. Here, we designed and tested new UCE probe sets derived from both genome and transcriptome data of an understudied molluscan class, Polyplacophora (chitons).

A mitogenomic phylogeny of chitons (Mollusca: Polyplacophora) [PDF]

BMC Evolutionary Biology, 2020
Background Polyplacophora, or chitons, have long fascinated malacologists for their distinct and rather conserved morphology and lifestyle compared to other mollusk classes.

Mapping molluscan endocrinology: a systematic and critical appraisal. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Biodiversity and Conservation of Marine Mollusks in the Indo-Pacific Convergence Zone. [PDF]

Ecol Evol
An integrated assessment has identified 11 priority mollusk conservation areas in the Indo‐Pacific Convergence Zone, which harbor 47.9% of species and 58.9% of threatened taxa, though only 18.7% have MPA coverage. Multi‐habitat zones, such as coral–mangrove areas, support 42.3% of molluscan diversity.

Molluscan Shells, Spicules, and Gladii Are Evolutionarily Deeply Conserved. [PDF]

J Exp Zool B Mol Dev Evol
Evolutionarily conserved transcription factor encoding genes and other genes are expressed in the epithelia that give rise to spicules (green) and/or shells (blue) in developmental stages of diverse mollusks, including polyplacophorans, aplacophorans, scaphopods, and cephalopods.

Chromosome-level genome assembly of the common chiton, Liolophura japonica (Lischke, 1873) [PDF]

GigaByte
Chitons (Polyplacophora) are marine molluscs that can be found worldwide from cold waters to the tropics, and play important ecological roles in the environment. However, only two chiton genomes have been sequenced to date.

Primer registro formal del quitón incubador Calloplax vivipara (Polyplacophora, Callistoplacidae) en Perú

Revista Peruana de Biología, 2023
Calloplax vivipara (Plate, 1899) se registra formalmente por primera vez en el litoral sur peruano. Cuatro ejemplares fueron encontrados en el intermareal pedregoso debajo de bloques de piedras en Islay, Arequipa, en diciembre de 2013 y octubre de 2019 ...
