A polysaccharide deacetylase from Puccinia striiformis f. sp. tritici is an important pathogenicity gene that suppresses plant immunity

Summary The cell wall of filamentous fungi, comprised of chitin, polysaccharide and glycoproteins, maintains the integrity of hyphae and protect them from defence responses by potential host plants. Here, we report that one polysaccharide deacetylase of Puccinia striiformis f. sp. tritici ( Pst ), Pst_13661, suppresses Bax‐induced cell death in plants and Pst_13661 is highly induced during early stages of the interaction between wheat and Pst ....
