| Abstract: | Cronartium quercuum f.sp. fusiforme is the pathogen that incites fusiform rust disease of southern pine species. To date, a number of host resistance genes have been mapped. Although genomic mapping studies have provided valuable information on the genetic basis of disease interactions in this pine-rust pathosystem, the interaction at the molecular level is poorly understood. To further our understanding of this interaction, we implemented a microarray study to examine the differential expression of genes in pathogen-challenged progeny of a full-sib loblolly pine family known to be segregating at a single dominant resistance gene (Fr1). Statistical analyses revealed shifts in gene expression that may reflect discrete stages of gall development. |
