Project description:Halohasta litchfieldiae and Halorubrum lacusprofundi are important members of Deep Lake in Antarctica, representing ~44% (the most abundance) and ~10% (the 3rd most abundance) of the lake population. Deep Lake is in the Vestfold Hills, East Antarctica (68°33’36.8S, 78°11’48.7E) and is 36 m deep, monomictic, and perennially cold (down to -20C) (DeMaere et al., 2013; Williams et al., 2014; Tschitschko et al., 2015; Tschitschko et al., 2016). In this project, using quantitative proteomics (8-plex iTRAQ labeling), proteins, pathways and cellular processes important for cold adaptation were determined for both Hht. litchfieldiae and Hrr. lacusprofundi. The data provided a new level of understanding about molecular mechanisms and regulatory networks involved in adaptation of the Antarctic haloarchaea to cold environment. DeMaere, M. Z., Williams, T.

Project description:Epigenetic variation has the potential to control environmentally dependent development and contribute to phenotypic responses to local environments. Environmental epigenetic studies of sexual organisms confirm the responsiveness of epigenetic variation, which should be even more important when genetic variation is lacking. A previous study of an asexual snail, Potamopyrgus antipodarum, demonstrated that different populations derived from a single clonal lineage differed in both shell phenotype and methylation signature when comparing lake versus river populations. Here, we examine methylation variation among lakes that differ in environmental disturbance and pollution histories. The differential DNA methylation regions (DMRs) identified among the different lake comparisons suggested a higher number of DMRs and variation between rural Lake 1 and one urban Lake 2 and between the two urban Lakes 2 and 3, but limited variation between the rural Lake 1 and urban Lake 3. DMR genomic characteristics and gene associations were investigated. Observations suggest there is no effect of geographic distance or any consistent pattern of DMRs between urban and rural lakes. Environmental factors may influence epigenetic response.
