Project description:Bone protein extractions for stable isotope analysis from 18th and 19th century humans from North America were analyzed for their protein content. Samples were classified by their stable isotope quality and changes between them were evaluated.
Project description:We investigated the transcriptional response of hybrid poplar (Populus trichocarpa x deltoides) leaves to a variety of stress treatments (insect feeding by Malacosoma disstria larvae, mechanical wounding, and wounding plus the application of insect oral secretions) over a 24 hour time course. Experiments were conducted using clonal trees under greenhouse conditions at the University of British Columbia. We used the 15.5K poplar cDNA microarray platform previously described by Ralph et al. (Molecular Ecology 2006, 15:1275-1297). Differentially expressed genes were determined using three criteria: fold-change between treated and untreated control leaves > 1.5-fold, P value < 0.05 and Q value < 0.05. This study identified > 1,000 differentially expressed genes in response to insect feeding and/or treatments that mimic insect feeding damage.
