“…U. crameri SCZ-6 has a genome size of 19.55 Mb, which is closer in size to the genomes of U. maydis (19.66 Mb) and S. scitamineum (19.42 Mb) than the other genus smut fungal genomes [11]. Furthermore, U. crameri SCZ-6 has a larger genome size than U. crameri strain Uc7 (18.82 Mb), which was isolated from Chengde, Hebei Province, China [68]. Importantly, the expression patterns of pathogenicity genes in U. crameri SCZ-6 at different inoculation times were clarified through transcriptomic analysis; however, we only completed sequencing and simple annotation for the genome of U. crameri Uc7 [68].…”

Ustilago crameri is a pathogenic basidiomycete fungus that causes foxtail millet kernel smut (FMKS), a devastating grain disease in most foxtail-millet-growing regions of the world. Here, we report an assembled high-quality genome sequence of U. crameri strain SCZ-6 isolated from the diseased grains of foxtail millet in Changzhi, Shanxi Province, China. The genome size is 19.55 Mb, consisting of 73 contigs (N50 = 840,209 bp) with a G + C content of 54.09%, and encoding 6576 predicted genes and 6486 genes supported by RNA-seq. Evolutionarily, U. crameri lies close to the barley smut U. hordei, and an obvious co-linearity was observed between these two smut fungi. We annotated the genome of U. crameri strain SCZ-6 using databases, identifying 1827 pathogen–host interaction (PHI)-associated genes, 1324 genes encoding fungal virulence factors, 259 CAZy-related genes, 80 genes encoding transporters, and 206 putative cytochrome P450 genes; their expression profiles at different inoculation time points were also detected. Additionally, 70 candidate pathogen effectors were identified according to their expression patterns and predicted functions. In summary, our results provide important insights into the pathogenic mechanisms of the pathogenesis-related genes of U. crameri and a robust foundation for further investigation.
