Transcriptional profiling of the rust fungus Cronartium quercuum f. sp. fusiforme (Cqf) during vegetative growth on 2 different hosts.

Project description:The purpose of this study was to make a single comparison between Cqf genes expressed during the vegetative stages of infection on the telial host (oak leaf) versus the aecial host (pine stem). A large proportion of genes were expressed in both hosts and significantly differentially expressed genes were enriched for candidate fungal effectors (small secreted proteins). These results suggest that the Cqf rust fungus uses a largely common set of genes to create two very different infection phenotypes. This study was based on hybridizations to custom microarrays containing features representing 8692 gene models from a Cqf genome sequencing project midpoint assembly. Two Agilent 4 X 44K microarray slides were populated with 60-mer probes (1 to 5 per transcript), designed using AgilentM-bM-^@M-^Ys web-based eArray software. Labeled target cRNA (complementary RNA) was generated using AgilentM-bM-^@M-^Ys Low Input Quick Amp Labeling Kit, such that oak and pine samples were labeled with either cy3 or cy5 an equal number of times across the experiment. Each microarray was hybridized with labeled cRNA target derived from a single oak sample and labeled cRNA target derived from a single pine sample. There were a total of eight oak sample replications and eight pine sample replications. Target hybridization and scanning were performed by the University of FloridaM-bM-^@M-^Ys Interdisciplinary Center for Biotechnology Research using standard procedures and an Agilent G250B Scanner.

Differential expression of pine and Cronartium quercuum f. sp. fusiforme genes in fusiform rust galls.

Project description:Cronartium quercuum f. sp. fusiforme is the causative agent of fusiform rust disease of southern pines in the United States. This disease is characterized by the formation of woody branch and stem galls. Differential display was used to identify pine genes whose expression is altered by C. quercuum f. sp. fusiforme infection and to identify C. quercuum f. sp. fusiforme genes that are expressed in fusiform rust galls. Six pine cDNAs that appeared to be differentially expressed in galled and healthy stems and 13 C. quercuum f. sp. fusiforme cDNAs expressed in galled tissues were identified. A probe that hybridizes specifically to C. quercuum f. sp. fusiforme 18S rRNA was used to estimate that 14% of the total RNA in fusiform rust galls was from C. quercuum f. sp. fusiforme. This finding was used to calibrate gene expression levels in galls when comparing them to expression levels in uninfected pines or in isolated C. quercuum f. sp. fusiforme cultures. According to Northern analysis and reverse transcriptase PCR analysis, all six of the pine clones were expressed at lower levels in galls than in healthy tissues. Seven of the nine C. quercuum f. sp. fusiforme clones that were assayed were expressed at higher levels in galls than in axenic culture. A number of the cDNAs encode proteins that are similar to those that play roles in plant development, plant defense, or fungal stress responses.
