Abstract: The Japanese Glandirana rugosa phylogenetically consists of four groups. However, the taxonomic identity of these groups still remains unclear. We determined the complete mitogenome sequences of the four groups of G. rugosa . The mitogenomes were 17,394–17,781 bp in length. The phylogenetic analysis clearly showed that the genus Glandirana is monophyletic and that the four groups of G. rugosa are separated into two clus… Show more

The Japanese islands were originally included in the Eurasian Continent as part of the southern and northern landmasses. The two landmasses were detached from the continent 18 million years ago. After that, the former was repeatedly connected to the Korean peninsula during glacial periods, but most of the latter was under seawater. Thus, all Japanese amphibians are undoubtedly derived from this nearby continent. However, it is unclear where the amphibians moved during the formation of the Japanese islands. To address the issue, we selected Glandirana rugosa as a representative of Japanese amphibians because this frog is the only species among amphibians in which nucleotide sequences of the mitochondrial genes and sex chromosome evolution have been deeply investigated. Then, we constructed time‐calibrated and RAxML phylogenetic trees based on nucleotide sequences of the mitochondrial genes of the Glandirana frogs in Japan and South Korea. Various sites were used to select SNP data from the Glandirana species and their sex chromosome evolution, and the cladograms we obtained suggest that ancient Glandirana frogs except for one group moved along with the southern landmass, when it was separated from the continent. The movements of the Glandirana frogs in Japan and South Korea obtained as results of this study will help scientists to understand the geographical changes that took place during the formation of the Japanese islands. This strategy is applicable to studying and understanding the movements of other amphibian species of the Eurasian and other continents.

Glandirana is a genus of frogs that includes G. rugosa, G. emeljanovi, G. minima, G. tientaiensis, G. susurra, G. nakamurai and G. reliquia. These frogs produce antimicrobial peptides (AMPs), which are endogenous antibiotics that possess antibacterial, antifungal, antiviral and anti-endotoxin activity and help keep the hosts free from infections. In these activities, microbial death is promoted by membranolytic mechanisms that are mediated by the cationic charge and amphiphilic α-helical structures of these peptides. In general, these peptides are selective for microbes, showing low levels of hemolytic and cytotoxic activity, as well as possessing other biological activities, including anticancer, antioxidative and insulinotrophic action. In this review, a brief overview of AMPs with a focus on those from amphibians is provided, along with the phylogeny and nomenclature of frogs and AMPs from the Glandirana genus. This review then provides a comprehensive, in-depth description of the antimicrobial and other biological activities of all AMPs produced by known frogs of the Glandirana for the period 1994 to 2024. This description includes a detailed discussion of the structure/function relationships and mechanisms involved in the membrane interactions that drive these biological activities, with comparisons between AMPs from the same frog and between frogs across the genus. Based on their biological properties, AMPs from frogs of the Glandirana genus have been proposed for investigation as potential therapeutic agents, such as in the treatment of cancers and diabetes, as well as antimicrobial agents in areas, including crop protection, the food industry and oral hygiene.
