Abstract:
... Starting with the beginning of the last century, a multitude of scientific studies has documented that the lunar cycle times behaviors and physiology in many organisms. It is plausible that even the first life forms adapted to the different rhythms controlled by the moon. Consistently, many marine species exhibit lunar rhythms, and also the number of documented “lunar-rhythmic” terrestrial species ...

At present, DUS of crop varieties are being established using morphological traits. DNA marker assay-based DUS testing would complement that based on morphological traits. Four markers, from a total of 220 tested SSR markers were polymorphic among two advanced b ...

Abstract:
... Despite many studies on tissue culture of Panax ginseng, the propagation of cultivars is still dependent on seeds due to low survival rate of plants produced in vitro. Healthy in vitro grown plants guarantee high survival rates after they are transferred to soil, but limited information exists on the optimum medium for the in vitro growth of P. ginseng. In this study, zygotic embryo culture was us ...

Abstract:
... Tigers are killed to supply a demand for many wildlife products despite a ban on commercial international trade. As populations decrease, products from substitute species (i.e. lions and leopards) have been fraudulently sold as tiger. DNA forensic techniques are needed to definitively identify tiger in order to secure prosecutions although this is complicated by the presence of numts. Therefore, w ...
