Abstract
Cold causes oxidative stress in living organisms, mainly caused by the accumulation of reactive oxygen species (ROS). In the antioxidant defense systems, Glutathione S-transferases (GSTs) play a vital role in the regulation of detoxification and redox balance of ROS. In this study, the P. canaliculata GST gene family were characterized using a genome-wide search of the conserved domain. Phylogenetic tree and domain composition analysis revealed that 30 PcGSTs belong to seven classes, including five in MAPEG, two in Mu, nine in Omega, 11 in Sigma, one in Rho, Theta and Alpha class, respectively. RNA-seq analysis revealed that most PcGSTs localized in mitochondria highly expressed in hepatopancreas, and most PcGSTs localized in cytoplasm highly expressed in kidney. A total of 12 PcGST genes were significantly up-regulated and PcGST12 was significantly down-regulated after cold acclimation. Ten PcGSTs were identified as DEGs under cold stress after cold acclimation. qRT-PCR revealed that the expression level of five PcGST genes were significantly varied during the cold acclimation. The present study investigated the characterization of the P. canaliculata GST gene family, extending our understanding of GST mediated cold acclimation and cold stress-response mechanisms in this invasive snail.

Lens transmittance shapes ultraviolet sensitivity in the eyes of frogs from diverse ecological and phylogenetic backgrounds. Proc Biol Sci 2020; 287:20192253.

Abstract
The amount of short wavelength (ultraviolet (UV), violet and blue) light that reaches the retina depends on the transmittance properties of the ocular media, especially the lens, and varies greatly across species in all vertebrate groups studied previously. We measured the lens transmittance in 32 anuran amphibians with different habits, geographical distributions and phylogenetic positions and used them together with eye size and pupil shape to evaluate the relationship with diel activity pattern, elevation and latitude. We found an unusually high lens UV transmittance in the most basal species, and a cut-off range that extends into the visible spectrum for the rest of the sample, with lenses even absorbing violet light in some diurnal species. However, other diurnal frogs had lenses that transmit UV light like the nocturnal species. This unclear pattern in the segregation of ocular media transmittance and diel activity is shared with other vertebrates and is consistent with the absence of significant correlations in our statistical analyses. Although we did not detect a significant phylogenetic effect, closely related species tend to have similar transmittances, irrespective of whether they share the same diel pattern or not, suggesting that anuran ocular media transmittance properties might be related to phylogeny.
