There is increasing evidence for frequent turnover in sex chromosomes in vertebrates. Yet experimental systems suitable for tracing the detailed process of turnover are rare. In theory, homologous turnover is possible if the new sex-determining locus is established on the existing sex-chromosome. However, there is no empirical evidence for such an event. The genus Takifugu includes fugu (Takifu...
Seminal plasma characteristics, such as ionic composition and pH, are important for sperm maturation further motility. In this work, a first batch of experiments evaluated the effect absence several ions (Na+, K+, Mg2+) in artificial seminal plasma, well pH seawater on activation pufferfish (Takifugu alboplumbeus, named before Takifugu niphobles). all experiments, total motility, progressive cu...
There are approximately 25 000 species in the division Teleostei and most are believed to have arisen during a relatively short period of time ca. 200 Myr ago. The discovery of 'extra' Hox gene clusters in zebrafish (Danio rerio), medaka (Oryzias latipes), and pufferfish (Fugu rubripes), has led to the hypothesis that genome duplication provided the genetic raw material necessary for the teleos...

Identification of new tetrodotoxin (TTX) analogs from TTX-possessing animals might provide insight into its biosynthesis and metabolism. In this study, four new analogs, 8-epi-5,6,11-trideoxyTTX, 4,9-anhydro-8-epi-5,6,11-trideoxyTTX, 1-hydroxy-8-epi-5,6,11-trideoxyTTX, and 1-hydroxy-4,4a-anhydro-8-epi-5,6,11-trideoxyTTX, were isolated from the newt, Cynops ensicauda popei, and their structures ...
background: a field study on the transfer of primordial radionuclides 238u, 232th, 40k and fallout radionuclides 210po in different plant species in tropical forest of western ghats environment is presented. material and methods: the top storey, second storey, shrubs and epiphytic plant species were chosen and concentration of these radionuclides in plant and soil were measured by employing gam...
Tetraodontidae (pufferfish) family members carry the smallest genomes among vertebrates, and these pocket-sized genomes have directly contributed to our understanding of the structure and evolution of higher animals. The grass pufferfish (Takifugu niphobles) could be considered a potential new model organism for comparative genomics and development due to the potential access to embryos, and av...
The genome of the pufferfish, Fugu rubripes (Fugu) is compact. With a similar gene complement to mammals and a genome size of just 400 Mb, gene density is high averaging one every 6-7 kb. Initial characterization of this genome has shown that although genes are much smaller and more densely spaced, their intron/exon structure is conserved with the resulting introns being small. There is little ...
