Embryos, larvae, and adults of Palaemonetes argentinus tolerate a wide range of salinities (1 to 25‰). While osmoregulatory capacities have previously been demonstrated in all postembryonic stages, little is known about the occurrence of osmoregulation during the embryonic phase. We examined ontogenetic and salinity-induced changes in the activity of a key enzyme involved in osmoregulation, Na+...

The complete mitochondrial (mt) genome of Trachemys scripta ssp. in Korea was sequenced and characterized. mt is constituted 37 genes (13 protein-coding genes, 22 transfer RNA 2 ribosomal genes) a control region. Phylogenetic analysis based on the showed that unidentified turtle had closely related to T. s. elegans, though it distinct morphology compared elegans. This study can provide informat...

Internal transcribed spacer 1 (ITS1) sequences from wild-type Exopalaemon carinicauda (N = 124) from the East China Sea were amplified and sequenced. Sequences were polymorphic and ranged from 388 to 583 bp in length. The average content of GC in sequences was significantly higher than that of AT. Altogether, 604 mutant sites with 123 haplotypes were detected; 46.7% were polymorphic sites. The ...

In order to identify some endophytic fungi in common yew trees, healthy plant samples were investigated. In this study, 10 fungal species including Absidia spinosa, Aureobasidium pullulans, Lecanicillium lecanii, Nemania serpens, Pseudodictyosporium elegans, Leucostoma persoonii, Epicoccum nigrum, Stachybotrys chartarum, Gibberella tricincta and Gibberella baccata were identified as endophytic ...

Hydrostatic pressure is an important, ubiquitous, environmental variable of particular relevance in the marine environment. However, it is widely overlooked despite recent evidence that some marine ectotherms may be demonstrating climate-driven bathymetric range shifts. Wide-ranging effects of increased hydrostatic pressure have been observed from the molecular through to the behavioural level....

The introduced oriental shrimp Palaemon macrodactylus has recently become widespread in temperate estuaries worldwide. However, this recent worldwide spread outside of its native range arises after a previous introduction to the US Pacific coast, where it was restricted for more than 30 years. Using a phylogeographic approach, the present work investigates the genetic history of the invasion of...

The molecular mechanism of aging, which has been a “black box” for many years, elucidated in recent and the nematode C. elegans, is model animal aging research, played major role its elucidation. From analysis elegans longevity-related mutant genes, signal transduction systems, with insulin/insulin-like growth factor system at core, have emerged. It become clear that this greatly affected by ex...

Caenorhabditis elegans (C. elegans) as a well-established multicellular model organism has been widely used in the biological field for half century. Its numerous advantages including small body size, rapid life cycle, high-reproductive rate, well-defined anatomy, and conserved genome, made C. one of most successful organisms. Discoveries obtained from have great contributions to research field...
