Figure Lengend Snippet: A Among a total of 10,078 orthologous groups of genes, 7485 are categorized as core (present in 100% of isolates; N = 22) and 2593 as accessory (present in <100% of isolates; N < 22); among these accessory genes, 1448 are softcore (present in ≥95% and <100%; N = 21), 793 are shell (5-95% of isolates; 21 > N ≥ 2), and 352 are cloud (present in less than 5% of isolates; N = 1). B Among 95 biosynthetic gene cluster families (BGCFs), 46 are categorized as core and 49 as accessory (9 are software, 25 are shell, and 15 are cloud). C The number of accessory gene families increases as the number of strains increases, suggesting additional sequencing is needed to fully capture A. latus gene content variation. N values varied between 1 and 26,393 depending on the number of strains being analyzed. D The number of accessory BGCFs substantially increases with additional isolates suggesting the gene content variation of BGCs has also yet to be captured. Notably the core genome is larger among gene families, whereas the accessory portion is larger among BGCFs. Errors bars indicate standard deviation. E Protein sequence lengths differed among gene categories wherein core and softcore genes are longer than shell and cloud genes ( N = 10,079). F As genes were less frequently observed among isolates, they were also functionally annotated less frequently. G The number of genes in BGCs differed per category wherein softcore BGCs tend to be smaller than BGCs categorized as core, shell, and cloud ( N = 2511). H Few BGCs are predicted to make known secondary metabolites. Source data are provided as Source Data files. For panels E and G , statistical comparisons were made using a Kruskal–Wallis rank sum test ( p < 0.01 for both tests); pairwise comparisons were made using the Dunn’s test. One, two, and three asterisks represents a significance threshold of 0.05, 0.01, and 0.001, respectively. In panels C – E , G , average values are depicted and error bars indicate the standard deviation from the mean.

Figure Lengend Snippet: A. latus (purple), A. spinulosporus (blue), and A. quadrilineatus (red) are indistinguishable in culture. At the genomic level, A. latus isolates have larger genome sizes and gene repertoires than other Aspergillus species and can be distinguished from its close relatives through Fluorescence-Activated Cell Sorting (or FACS) analysis of DNA content. Furthermore, amplification and sequencing of single-locus molecular markers, including taxonomically informative loci, is expected to show evidence of two distinct loci that are phylogenetically distinct in a single-locus phylogeny. At the phenotypic level, A. latus spores are larger than those of other species due to their larger genome size.
