The genome sequence and gene prediction of Marssonina brunnea f. sp. multigermtubi NL1 have not been determined by the Joint Genome Institute (JGI), but were provided by Qiang Cheng on August 20, 2020. In order to allow comparative analyses with other fungal genomes sequenced by the JGI, a copy of this genome is incorporated into Mycocosm. Please note that this copy of the genome is not maintained by Qiang Cheng and is therefore not automatically updated. JGI tools were used to automatically annotate predicted proteins.

Poplar leaf spot disease caused by Marssonina brunnea (Ellis & Everh.) Magnus, (Leotiomycetes, Ascomycota), is a widespread and devastating disease of poplar. M. brunnea is highly host-specific and has two formae speciales, M. brunnea f. sp. multigermtubi and M. brunnea f. sp. monogermtubi. M. brunnea f. sp. multigermtubi exclusively attacks poplars of the Aigeros and Tacamahaca sections, such as many cultivars of Populus deltoides, Populus × euramericana, and Populus simonii. In contrast, M. brunnea f. sp. monogermtubi only attacks Leuce poplars, such as Populus tomentosa.

The genome of one strain (MB_m1) of M. brunnea f.sp. multigermtubi has been sequenced in 2012. Here we provide the genomic sequence of M. brunnea f. sp. monogermtubi NL1, which was isolated from leaf spot of P. tomentosa. Preliminary comparison of the genomes of M. brunnea f. sp. monogermtubi NL1 and M. brunnea f. sp. multigermtubi MB_m1 showed extensive differences.
