Comparative Chloroplast Genomics Reveals the Evolution of Pinaceae Genera and Subfamilies

As the largest and the basal-most family of conifers, Pinaceae provides key insights into the evolutionary history of conifers. We present comparative chloroplast genomics and analysis of concatenated 49 chloroplast protein-coding genes common to 19 gymnosperms, including 15 species from 8 Pinaceous genera, to address the long-standing controversy about Pinaceae phylogeny. The...

Function of being colorful in web spiders: attracting prey or camouflaging oneself?

Bright body colorations of orb-weaving spiders have been hypothesized to be attractive to insects and thus function to increase foraging success. However, the color signals of these spiders are also considered to be similar to those of the vegetation background, and thus the colorations function to camouflage the spiders. In this study, we evaluated these 2 hypotheses by field...

Tumor promotion by hydrogen peroxide in rat liver epithelial cells

Reactive oxygen species, including H2O2, play an important role in the tumor promotion process. Using an in vitro model of tumor promotion involving the rat liver epithelial oval cell line T51B, the tumor promoting activity of H2O2 in N-methyl-N′-nitro-N-nitrosoguanidine-initiated cells was studied. In this assay system, the promoting effect of H2O2 is evidenced by the formation...
