Abstract
Soybean is one of the top five agricultural products in the United States and is highly susceptible to Phakopsora pachyrhizi, an exotic obligate biotrophic fungus. The little amount of genomic information about P. pachyrhizi limits understanding of the soybean–soybean rust pathogen interaction and the possibility of engineering resistance to this pathogen in soybean. Illumina mRNA‐Seq analysis revealed P. pachyrhizi genes expressed during a biotrophic interaction between P. pachyrhizi and soybean during fungal sporulation 10 days after inoculation. Approximately 2·4 million DNA sequences representing portions of potential P. pachyrhizi genes were assembled into 32 940 contigs that were used to search against expressed sequence tag (EST), protein and conserved domain databases. About 7500 contigs represent newly discovered P. pachyrhizi sequences. Of these, 527 shared similarity to genes encoding fungal proteins involved in different metabolic pathways such as galactose and glycogen metabolism, glycolysis, the citrate cycle, fatty acid metabolism, amino acid metabolism, proteolysis, protein synthesis, cell cycle division and mitosis, and cell wall biogenesis. Almost 7000 potential P. pachyrhizi genes are still of unknown function. Such information may be useful in the development of new methods of broadening resistance of soybean to P. pachyrhizi, including the silencing of important P. pachyrhizi genes, and also to understand the molecular basis of soybean–P. pachyrhizi interactions.
