Abstract excerpt

The rice blast fungus Magnaporthe oryzae differentiates a specialized infection structure called an appressorium to invade rice cells. In this report, we show that CBP1, which encodes a chitin-deacetylase, is involved in the induction phase of appressorium differentiation. We demonstrate that the enzymatic activity of Cbp1 is critical for appressorium formation. M. oryzae has six CDA homologues in addition to...
