Project description:Using WGBS we investigated blood DNA methylation profiles of Cooinda the Alpine dingo and determined putative regulatory elements (unmethylated regions, UMRs, and lowly methylated regions, LMRs).

Pleiotropic expression of endogenous genes upon fungus infection of wheat plants containing anti-fungal transgenes

Project description:Recent attempts to increase endogenous disease resistance of plants by overexpression of anti-fungal transgenes have shown a potential of this method. However, it has also been shown that such improvements are usually small. One of the obvious reasons for this low anti-fungal effect might be the regulation of endogenous genes in parallel. In this project, we will study the effect of anti-fungal transgenes on the endogenous gene expression. Such effects might relate to substantial equivalence which is a biosafety issue of concern to the public. The GeneChip Wheat Genome Array will be used to detect expression of defence response genes and key genes of metabolic pathways. We will use wheat plants transformed with anti-fungal gene of specific effect against a small group of seed transmitted, pathogenic fungi (KP4 against smuts and bunts). Transformed spring wheat line will be challenged by stinking smut (inhibited by KP4). The effect on the endogenous gene expression will be tested for plants grown in the field in collaboration with the USDA Department. This work will contribute to our understanding of plant defence responses in general and may allow improving strategies to strengthen these responses.

Metagenomic analysis revealed the microbial-mediated soil organic carbon loss under the degeneration succession in alpine meadow

Project description:Land cover change has long been recognized that marked effect the amount of soil organic carbon. However, little is known about microbial-mediated effect processes and mechanism on soil organic carbon. In this study, the soil samples in a degenerated succession from alpine meadow to alpine steppe meadow in Qinghai-Tibetan Plateau degenerated, were analyzed by using GeoChip functional gene arrays.

Comparative proteomics analysis reveals the adaptation strategies of the alpine plant Potentilla saundersiana along the altitude gradient of the Northwestern Tibetan Plateau

Project description:The altitude gradient limits the growth and distribution of alpine plants.Alpine plants have developed strategies to survive the extremely cold conditions prevailing at high altitudes; however, the mechanism underlying the evolution of these strategies remains unknown. The alpine plant Potentilla saundersiana is widespread in the Northwestern Tibetan Plateau. In this study, we conducted a comparative proteomics analysis to investigate the dynamic patterns of protein expression of P. saundersiana located at five different altitudes. We detected and functionally characterized 118 differentially expressed proteins. Our study confirmed that increasing levels of antioxidant proteins, and their respective activities, and accumulation of primary metabolites, such as proline and sugar, confer tolerance to the alpine environment in P. saundersiana. Proteins species associated with the epigenetic regulation of DNA stability and post-translational protein degradation were also involved in this process. Furthermore, our results showed that P. saundersiana modulated the root architecture and leaf phenotype to enhance adaptation to alpine environmental stress through mechanisms that involved hormone synthesis and signal transduction, particularly the cross-talk between auxin and strictosidine. Based on these findings, we conclude that P. saundersiana uses multiple strategies to adapt to the high-altitude environment of the Northwestern Tibetan Plateau.
