“…We obtained a highly similar match (98.7% nucleotide identity) to Zasmidium syzygii (NR_111826.1), supporting that the assembled isolate belongs to the Zasmidium genus. In line with this finding, previous studies have found Zasmidium isolates on symptomatic banana leaves (Arzanlou et al, 2008;Crous et al, 2021), and other Zasmidium species are reported to cause leaf spot diseases on other plant species such as citrus (Aguilera-Cogley et al, 2017;An et al, 2021;Han et al, 2015). The Zasmidium genome assembly we report here is less fragmented and 4 Mb larger than the previous genome assembly of a Zasmidium species; Z. cellare.…”

Accurate taxonomic classification of samples from infected host material is essential for disease diagnostics and genome analyses. Despite the importance, diagnosis of fungal pathogens that cause banana leaf diseases remains challenging. Foliar diseases of bananas are mainly caused by threePseudocercosporaspecies, of which the most predominant causal agent isP.fijiensis. Here, we sequenced and assembled four fungal isolates obtained from necrotic banana leaves in Bohol (Philippines) and obtained a high-quality chromosome-level genome assembly for one of these isolates. Using PCR diagnostics, the samples were initially identified asP. fijiensis, yet the assembly size was consistently 30 Mb smaller than expected. Based on the ITS sequences, we identified the samples asZasmidium syzygii. TheZasmidium syzygiigenome assembly is 42.5 Mb in size distributed over 16 chromosomes, eleven of which are complete. The genome contains 98.6% of the expected single-copy BUSCO genes and we predicted 14,789 protein-coding genes and 10.3% repeats. The three other genome assemblies based on short-read data are less continuous but have similar genome sizes (40.4 42.4 Mb) and contain between 96.5% and 98.4% BUSCO genes. All four isolates have identical ITS sequences and are distinct fromZasmidiumisolates that have been previously sampled from banana leaves. We thus report the first chromosome-level genome assembly of a member of theZasmidiumgenus, forming an essential resource for further analysis to enhance our understanding of the diversity of pathogenic fungal isolates as well as fungal diversity.

“…Didymellaceae was established by De Gruyter et al (2009) with Didymella as the type genus. It is the largest family in the Pleosporales and accommodates more than 5400 taxon names (Crous et al 2004), including saprobic, endophytic and pathogenic species (Aveskamp et al 2008, Aveskamp et al 2010, Marin-Felix et al 2017. A great part of Didymellaceae species are reported as plant pathogens, which cause severe economic losses to many crops (Aveskamp et al 2008).…”

Thunbergia grandiflora belongs to the family Acanthaceae and is a widely distributed dicotyledonous plant in tropical and subtropical regions. Three isolates of Allophoma (Dothideomycetes, Pleosporales, Didymellaceae) were collected from leaves of T. grandiflora in Guangxi Province, China. Phylogenetic analyses of a combined ITS–LSU–rpb2–tub2 dataset indicate that one of our three strains represents an undescribed species with close affinity to A. minor and the other two strains clustered amongst other isolates of A. pterospermicola. Evidence from morphology and sequence analysis indicates that GUCC 2070.7 is a new species that we introduce here as A. thunbergiae. This is the first report about taxa of Allophoma from this host plant.
