A chromosome-scale genome assembly resource for Myriosclerotinia sulcatula infecting sedge grass (Carex sp.)
<p>The fungus <em>Myriosclerotinia sulcatula</em> is a close relative of the notorious polyphagous plant pathogens <em>Botrytis cinerea</em> and <em>Sclerotinia sclerotiorum</em> but exhibits a host range restricted to plants from the <em>Carex</em>genus (<em>Cyperaceae</em> family). To date, there are no genomic resources available for fungi in the <em>Myriosclerotinia</em>genus. Here, we present a chromosome-scale reference genome assembly for <em>M. sulcatula</em>. The assembly contains 24 contigs with a total length of 43.53 Mbp, with scaffold N<sub>50</sub> of 2,649.7 kbp and N<sub>90</sub> of 1,133.1 kbp. BRAKER-predicted gene models were manually curated using WebApollo, resulting in 11,275 protein-coding genes that we functionally annotated. We provide a high-quality reference genome assembly and annotation for <em>M. sulcatula</em> as a resource for studying evolution and pathogenicity in fungi from the <em>Sclerotiniaceae</em> family. </p>

Figure 48 Maximum likelihood phylogeny from 757 concatenated UCE loci (average 113231 base pairs/taxon) analyzed primarily for the 23 Core Taxa in black (IQ-TREE, partitioned by locus). Topology is identical in unpartitioned analyses, with nearly identical branch lengths. Bootstrap percentage values from 1000 replicates shown for each clade. Where two numbers are shown, the first is the bootstrap percentage for the partitioned analysis, the second for the unpartitioned analysis. Where one number is shown, both analyses yielded the same percentage. An analysis of the All Taxa dataset, including the weakly-sequenced taxa in grey, yielded the same topology.

Figure 165 Chromosome evolution in sitticines. Ancestral nodes show the most parsimonious reconstruction of the evolution of Y via X-autosome fusions (black) from the X1X20 sex chromosome system (white). Phylogeny from Figure 48 with species added as follows: Attinella concolor is very similar in body and genitalia to A. dorsata; likewise Sittisax saxicola to S. ranieri; Attulus caricis position based on COI results (Fig. 96). The similar pair A. cutleri and A. striatus were placed as sisters to the floricola group based on their inclusion in the floricola group by Logunov and Kronestedt (1997) and in Sittiflor by Prószyński (2017a). Base chromosome number is directly the number of autosomes if the species has XX0 sex chromosomes, but is interpreted as the number of autosomes +2 if the species has XXY sex chromosomes (apparently derived by a single fusion that would have consumed an autosomal pair), or + 4 if XXXY (apparently derived by two fusions that would have consumed two pairs). Uncertain scoring is shown by parentheses (see Table 2).
