摘要： Nigrospora oryzae is one of several fungal pathogens known to cause brown streaks, leaf spots, and latent infections in rice. In this study, the entire 42.09 -Mb genome of N. oryzae was sequenced at a depth of 169x using the Oxford Nanopore Technologies platform. The draft genome sequence was comprised of 26 scaffolds, possessed an average GC content of 58.83%, and contained a total of 10,688 protein -coding genes. Analysis of the complete genome sequence revealed that CAZyme-encoding genes account for 6.11% of all identified genes and that numerous transcription factors (TFs) associated with diverse biological processes belong predominantly to Zn-clus (22.20%) and C2H2 (10.59%) fungal TF classes. In addition, genes encoding 126 transport proteins and 3307 pathogen-host interaction proteins were identified. Comparative analysis of the previously reported N. oryzae reference strain GZL1 genome and the genome of a representative strain ZQ1 obtained here revealed 9722 colinear genes. Collectively, these findings provide valuable insights into N. oryzae genetic mechanisms and phenotypic characteristics.
