Protein biomarkers associated with frozen Japanese puffer fish (Takifugu rubripes) quality traits.

This study was designed to investigate proteome changes in Japanese puffer fish (Takifugu rubripes) during short- and long-term frozen storage. In total, 1484 proteins were quantified, and 164 proteins were identified as differential abundance proteins (DAPs) in Japanese puffer fish from two frozen storage treatment groups (14 days and 60 days) compared with the fresh control group. Correlation analysis between the DAPs and quality traits of the puffer fish muscle showed that 106 proteins were correlated closely with colour and texture (hardness, elasticity, and chewiness).

The complete mitochondrial genome of the hybrid of (♀) × (♂).

The complete mitochondrial genome of the hybrid of (♀) × (♂) was sequenced and characterized in this study. The hybrid mitochondrial DNA, with a total length of 16,443 bp, contain 37 genes, including 13 protein-coding genes, 22 tRNAs genes, and 2 rRNA gene. There are two noncoding regions: the origin of light-strand replication (OL) and control region (D-loop).

Comparative RNA-Seq analysis of differentially expressed genes in the testis and ovary of Takifugu rubripes.

Takifugu rubripes is a classical model organism for studying the role of gonad organogenesis in such physiological processes as fertilization, sex determination, and sexual development. To explicitly investigate the mechanism associated with gonad organogenesis in T. rubripes, we obtained 44.

[Species composition, distribution and phenological characters of pollen-allergenic plants in Beijing urban area].

In order to know the species composition, distribution pattern, and phenological characteristics of pollen-allergenic plants in Beijing urban area, an investigation was made, combined with literature survey and experts interviews. The results showed that within the fifth ring of Beijing, there were 99 pollen-allergenic plant species belonging to 32 genera and 19 families, among which, 52 species were native plants, accounting for 52.5% of the total, 26 species were introduced from other regions of China, occupying 26.
