Gene expression during Ustilago maydis diploid filamentous growth: EST library creation and analyses

Ustilago maydis is an important model system for the plant pathogenic smut and rust fungi. Critical to the continued development of this model is establishing genomic resources. We have constructed a cDNA library from a forced diploid culture of U. maydis growing as filaments and have generated 7455 ESTs that are assembled into 3074 contiguous sequences. This represents as much as 46% of the coding capacity predicted for U. maydis. BLAST searches with a similarity cutoff of E
