摘 要:The necrotrophic fungus Rhizoctonia cerealis is the causal agent of devastating diseases of cereal crops including wheat(Triticum aestivum).We present a high-quality genome assembly of *** Rc207,a virulent strain causing wheat sharp *** assembly(56.36 Mb)is composed of 17.87%repeat sequences and 14,433 predicted protein-encoding *** Rc207 genome encodes a large and diverse set of genes involved in pathogenicity,especially rich in those encoding secreted proteins,carbohydrateactive enzymes(CAZymes),peptidases,nucleases,cytochrome P450,and secondary metabolismassociated *** secretory protein-encoding genes,including CAZymes,peroxygenases,dehydrogenases,and cytochrome P450,were up-regulated during fungal infection of *** identified 831 candidate secretory effectors and validated the functions of 10 up-regulated candidate effector *** them,nine were confirmed as necrotrophic pathogen’s effectors promoting fungal *** potential mobile or plastic genomic regions rich in repeat sequences suggest their roles in fungal adaption and virulence-associated genomic *** study provides valuable resources for further comparative and functional genomics on important fungal pathogens,and provides essential tools for development of effective disease control strategies.
