Molecular characterization of cathelicidin in tiger frog (Hoplobatrachus rugulosus): Antimicrobial activity and immunomodulatory activity.

Cathelicidins are an important antimicrobial peptide family and are expressed in many different vertebrates. They play an important role in the innate immune system of the host. However, amphibian cathelicidins are poorly understood.

Partial mitochondrial genome of the Sanchiang Tree Toad (Anura: Hylidae).

We reported the partial mitochondrial genome (mitogenome) for (Anura: Hylidae), a arboreal frog and endemic in China. The length of partial mitogenome of was 15,664 bp, and contained PCGs (COX1-3, ND1-6, ND4L, ATP6, ATP8 and CYTB), 2 ribosomal RNA genes, 22 transfer RNA genes, and 2 non-coding regions of a L-strand replication origin and a partial loop region. The overall base composition of the sequence is 29.

The combined effects of temperature and aromatase inhibitor on metamorphosis, growth, locomotion, and sex ratio of tiger frog () tadpoles.

Background: The tiger frog () is widely raised by many farms in southern region of China as an economically edible frog. The growth, development, and sexual differentiation of amphibians are influenced by temperature and steroid hormone level. However, the problem of hormone residues is caused by the addition of exogenous hormones in frog breeding, it is worth considering whether non-sterol aromatase inhibitors can be used instead of hormones.

Acoustic divergence in advertisement calls among three sympatric species from East China.

Background: Species-specific advertisement calls are the main mechanism of transmitting information between individuals in anuran amphibians and are therefore indispensable for anuran survival and reproduction. Survey methods that monitor these calls can be used for rapid species recognition, behavioral experiments, and conservation monitoring. In this study, we described in detail 10 call parameters from three sympatric species in the genus and analyzed the differences in call parameter among these species to provide a basis for systematic monitoring, acoustic analysis and taxonomic study of this genus.
