AI Article Synopsis
- Many species of red algae in the Rhodophyta phylum are important for human nutrition and medicine, with recent advancements in their classification accuracy.
- The study analyzes the complete chloroplast and mitochondrial genomes of three laver species - Neoporphyra dentata, Neoporphyra seriata, and Neopyropia yezoensis - aiming to characterize their genetic organization and develop molecular markers.
- Findings include an average of 212 protein-coding genes in the chloroplast and 25 in the mitochondria of the species, along with the creation of 12 species-specific markers to help distinguish these species in research and industry.
Article Abstract
Background: Many species of red algae belonging to the phylum Rhodophyta are consumed by humans as raw materials for nutrition and medicine. As the seaweed market grows, the importance of the laver species has increased. The classification of red algal species has changed significantly, and the accuracy of this classification has improved significantly in recent years. Here, we report the complete circular genomes of the chloroplasts (cp) and mitochondria (mt) of three laver species (Neoporphyra dentata, Neoporphyra seriata, and Neopyropia yezoensis).
Objective: This study aims to assemble, annotate, and characterize the organization of the organelle genomes of three laver species, conduct comparative genomic studies, and develop molecular markers based on SNPs.
Methods: We analyzed organelle genome structures, repeat sequences, sequence divergence, gene rearrangements, and phylogenetic relationships of three laver species.
Results: The chloroplast genomes of the three species contained an average of 212 protein-coding genes (PCGs), while the mitochondrial genomes contained an average of 25 PCGs. We reconstructed the phylogenetic trees based on both chloroplast and mitochondrial genomes using 201 and 23 PCGs (in cp and mt genomes, respectively) shared in the class Bangiophyceae (and five species of Florideophyceae class used as an outgroup). In addition, 12 species-specific molecular markers were developed for qRT-PCR analysis.
Conclusions: This is the first report of Neoporphyra seriata complete organellar genomes. With the results, this study provides useful genetic information regarding taxonomic discrepancies, the reconstruction of phylogenetic trees, and the evolution of red algae. Moreover, the species-specific markers can be used as fast and easy methods to identify a target species.

The harlequin ladybird, , is a predatory beetle used globally to control pests such as aphids and scale insects. Originating from East Asia, this species has become highly invasive since its introduction in the late 19th century to Europe and North America, posing a threat to local biodiversity. Intraguild predation is hypothesized to drive the success of this invasive species, but the underlying mechanisms remain unknown.

Mosquitoes are the primary vectors of arthropod-borne pathogens. Aedes aegypti is one of the most widespread mosquito species worldwide, responsible for transmitting diseases such as Dengue, Zika, and Chikungunya, among other medically significant viruses. Characterizing the array of viruses circulating in mosquitoes, particularly in Aedes aegypti, is a crucial tool for detecting and developing novel strategies to prevent arbovirus outbreaks.

In the last decade, the emergence of variant strains of avian orthoreovirus (ARV) has caused an enormous economic impact on the poultry industry across China and other countries. This study aimed to evaluate the molecular evolution of the ARV lineages detected in Chinese commercial broiler farms. Firstly, ARV isolation and identification of commercial broiler arthritis cases from different provinces in China from 2016 to 2021 were conducted.

Variation in parenting behavior is widespread across the animal kingdom, both within and between species. There are two ecotypes of the three-spined stickleback fish () that exhibit dramatic differences in their paternal behavior. Males of the common ecotype are highly attentive fathers, tending to young from eggs to fry, while males of the white ecotype desert offspring as eggs.
