Project description:We report the transcriptional response to Colorado potato beetle herbivory in leaves of the highly beetle resistant Solanum chacoense diploid line USDA8380-1 (80-) and a susceptible F2 individual (EE501F2_093) derived from a cross between 80-1 and a beetle susceptible line S. chacoense M6. Sampling tissue in a time course during adult Colorado potato beetle feeding provides novel insight to the transcriptomic defense response to this important pest.

Project description:The intent was to study, from transcriptome analysis, shade and drought responses in Solanum tuberosum (potato). We performed Illumina 50 bp single-end RNA-seq in tissues of control and treated var. Spunta wild-type plants. Drought experiments also included two independent AtBBX21-overexpressing (BBX21-OE) potato lines.

Project description:The late blight pathogen, Phytophthora infestans has a broad host range within the Solanaceae family, including yellow potato (Solanum phureja). The disease caused by P. infestans in S. phureja is poorly understood and is a major concern in Colombia. Expressed Sequence Tag (EST) libraries obtained from a normalized library constructed from healthy plant tissue revealed high levels of sequence similarity between S. phureja and S. tuberosum. Then, utilizing Serial Analysis of Gene Expression and high-throughput sequencing (SAGE-Solexa), we characterized yellow potato gene expression during infection by P. infestans. Four-week-old yellow potato plants were inoculated with P. infestans and were collected at 12 and 72 hours post inoculation for RNA extraction. We detected differentially expressed genes by comparing inoculated to non-inoculated and resistant to susceptible plants. The discovery and characterization of the proteins mediating this host–pathogen interaction enable the understanding of the pathosystem and is the key for developing resistant plants.

Keywords: SAGE-Solexa, inoculation response, transcript profiling, Solanum phureja, Phytophthora infestans Four-week-old yellow potato (Solanum phureja) plants were inoculated with Phytophthora infestans and were collected and flash frozen in liquid nitrogen at 12 and 72 hours post inoculation, as well as mock inoculated, for RNA extraction. 2 yellow potato cultivars (resistant and susceptible) were used for each experiment. Mock inoculated plants were collected in each replicate. RNA obtained from each of the three biological replicates was pooled to obtain a single RNA sample for each timepoint X cultivar combination. A total of 6 different SAGE libraries were thus obtained. For all libraries, Illumina sequencing was performed at Canada´s Michael Smith Genome Sciences Centre.

Project description:Late blight, caused by the oomycete Phytophthora infestans, is one of the most damaging potato diseases. Genetic resistance is one of the most effective means to control the destruction caused by this pathogen. Transgenic potato lines harboring a resistance gene, RB, confer broad-spectrum, rate-reducing late blight resistance. A microarray approach was used to understand what genes are manipulated in the potato background after the addition of the RB gene that contribute to the late blight resistant phenotype. Keywords: Time course, disease state analysis

Project description:The goal of this study was to calculate the degree of substantial equivalence between a GM potato line modified for late blight resistance and corresponding non-GM controls in the presence/absence of P. infestans inoculation. The GM phenotype was conferred through the introduction of the Rb gene which has been previously cloned from Solanum bulbocastanum (Song et al. 2003). The resulting GM phenotype was characterised by the expression of strong, partial resistance to P. infestans. By obtaining an expression profile from a GM and non-GM population before and after exposure to P. infestans, this effectively provides for the completion of two risk assessments: impact on the potato transcriptome of plus/minus genetic modification; before and after exposure to the pathogen. For each biological replicate, individuals from three separate GM lines (A, B, C) and three separate non-GM lines (D, E, F) were randomly sorted and cultivated for analysis. Each GM line contained an independent, single transgene insertion, which was verified through Southern Blot analysis. One day prior to pathogen exposure, the 4-week-old potato plants were transferred into a growth chamber with a 16-h light period, 90% relative humidity at a temperature of 15C. Plants were randomly selected and 14 individuals/line were inoculated with a field isolate of P. infestans. An additional 14 plants/line were sprayed with water. Inoculations were made with a sporangial suspension of 20,000/mL and plants were sprayed until run-off. Twenty-four hours post-inoculation, leaf tissue was collected from 9 plants per treatment, flash frozen in liquid nitrogen and pooled. Total leaf RNA was extracted using Trizol and the whole experiment was repeated three times (three biological replicates). Keywords: Direct comparison 19 hybs total
