apoplast of S. bicolor in response to the fungal pathogen · Colletotrichum graminicola. The accumulation of phytoalexin starts with the occurrence of spherical cytoplasmic inclusions of about 1 m in diameter that merge to form a large entity of ~ 20 m diameter. · Similarly, during barley-powdery mildew interaction the deposition of H2O2 containing vacuole struc tures were observed. · Ultrastructural analysis showed that these vesicle-like bodies consist of a broad range of cellular structures that includes miniature cell wall appositions, para-mural bodies, and multivesicular bodies. · This condition reflects the specialized transport of different antimicrobial proteins, regulatory polypeptides, cell wall components, and other defense-related cargo. · SNARE homologues are involved in vesicle-mediated resistance to stripe rust (Puccinia striiformis f. sp. tritici).
