Project description:Gene expression profiles of Populus deltoides induced by fungal pathogenic Marssonina brunneain iduring time-course infection. We used Affymetrix poplar genome genechip microarrays to analyze the full transcript expression underlying time-course infection and identified significantly differently expressed genes during the infection process. 2-year-old seedlings of P. deltoides grown were innoculated with the suspension of the pathogenic spores throught leaves spraying. Collecting the samples at interval time of 2 days and one week. Affymetrix poplar genechip was hired to investigate the full transcripts changed of the poplar response to the pathogen attack during the time.

Project description:Diseases of poplar caused by the fungal pathogen Sphaerulina musiva and related species are of growing concern, particular with the increasing interest in intensive popluliculture to meet increasing energy demands. S. musiva is able to cause infection on leaves, resulting in defoliation and canker formation on stems. To gain a greater understanding of the different responses of poplar species to infection with their natural Sphaerulina species, RNA-seq was conducted on leaves of Populus deltoides, P. balsamifera and P. tremuloides infected with S. musiva, S. populicola and a new undescribed species Ston1, respectively. Progression of disease symptoms, pathogen growth and host response were detected. Through the time course of infection, different and species-specific metabolic pathways were activated. In all three species, genes associated with growth and development were down-regulated, while genes involved the phenylpropanoid, terpenoid and flavonoid biosynthesis were up-regulated. Poplar defensive genes were expressed early in P. balsamifera and P. tremuloides, but delayed in P. deltoides, which correlated with the rate of disease symptoms development. This data gives an insight into the large differences in timing and expression of genes between poplar species being attacked with their native associated Sphaerulina pathogen.

Project description:Global gene expression pattern of different poplar tissue types were determined using a Nimblegen microarray based on JGI v1.1 gene models. All tissue except reproductive tissue were obtained from the same clone used for the poplar genome sequencing project (Populus trichocarpa Nisqually-1). Reproductive tissue were from wild Populus trichocarpa trees.

Project description:To identify candidate genes involved in maturation and flowering, we conducted microarray expression studies using two poplar genotypes (Populus trichocarpa x P. deltoides hybrids) represented in continuous age gradients of one to six years. We designed 70-mers for 228 poplar genes and microarray studies were carried out using the microplate-based 96-well BioGridArray platform (GeneXP Biosciences). Floral buds, vegetative buds and shoot tips were collected at different seasonal time points from juvenile and adult trees and from both basal and upper branches of mature trees.

Project description:affy_rewatering_poplar - rewatering - Biological question (15 lines max): Xylogenesis is a complex process and is highly influenced by environmental factors. Numerous studies have shown xylem structural acclimation to moderate and long-lasting water deficits. A decrease in cell lumen size and an increase in vessel density are generally observed. Other preliminary experiments in our laboratory focusing on a short and progressive drought-rewatering cycle in poplar show a gradual decrease in fibre size with decreasing water availability and an important rise in vessel number with irrigation recovery. This suggests a reorientation during the early stages of cambial derivatives differentiation towards vessel formation. The aim of this study is to characterize global gene expression in young differentiating xylem of poplar in response to a drought-rewatering cycle. Results should provide a comprehensive genomic basis for the xylem structural modifications observed.-The experimental design consisted in a differential water supply. Experiments were done on tilted trees to induce tension wood formation. Trees were regularly irrigated at full capacitance until July 18, 2007, the beginning of the experiment. Two sets of plants were designed. For each set, irrigation was withheld until July 25, 2007. At this time, one of the two sets (treated-sample) was re-irrigated at full capacitance during 14hrs (WDR) while the other one was maintained under water deficit (WD). Samples were collected after the 14hrs for all trees. Keywords: treated vs untreated comparison 6 arrays - poplar
