Mity model: Tatranychus urticae, a candidate for chelicerate model organism

Article Abstract:

A chelicerate genetic model, namely the two-spotted spider mite Tetranychus urticae with the smallest genome of any athropod determined is developed to study the developmental genetics of chelicerates. The model gives a complete analysis of the less studied arthropods, chelicerates, which are found to vectors of human diseases and is important to the fields of medicine, as well as agriculture.

Gene flow among habitat patches on a fragmented landscape in the spider Argiope trifasciata (Araneae: Araneidae)

Article Abstract:

Genetic variability and gene flow in populations of banded garden spider reveal a 7.5% mean heterozygosity and a mean polymorphism of 39.3% per population. Absence of significant interpopulation genetic variation is discussed in terms of spiderling aerial dispersion and other factors involved in the gene flow.

CD38 regulates oxytocin secretion and complex social behavior

Article Abstract:

The Jin and colleagues studies the effects of CD38 on oxytocin secretion by mouse model and maternal behavior. The results show that CD38 regulates the social behavior and oxytocin release.
