“…To confirm the phylogenetic placement of the fungi in Hamamelidaceae and their relationship, a phylogenetic tree was established based on 28S ( Figure 2 ). The phylogenetic results were mostly congruent with recent studies of rust fungi ( Aime and Mctaggart, 2020 ). However, the support value was lower because only the 28S gene was used in the analysis.…”

Hamamelidaceae is composed of woody plant taxa of important economic value; however, reports on diseases affecting these plants are rare. Three kinds of rusts were studied, of which the first one is characterized by catenulate spores in peridiate columnar sori on Sycopsis sinensis, the second one produces two-celled pedicellate teliospores in pulvinate sori on S. sinensis and Corylopsis spp., and the last one produces aeciospores in cup-shaped aecia on Hamamelis spp. Phylogenetic analyses indicated that the three species belong to the same genus in Pucciniaceae. The first fungus is distinct in teliospore morphology, producing one-celled catenulate spores in peridiate columnar sori and molecular phylogeny from species of other genera. Thus, it is described herein as a new genus and species Novopuccinia sycopsis-sinensis in Pucciniaceae. The latter two species were reported as Puccinia corylopsidis and Aecidium hamamelidis, respectively. However, phylogenetic analysis using ITS and 28S genes has revealed that these are closely related to the new genus and species. By combining host, distribution, and evolutionary hypothesis of rust fungi with endocyclic life cycle, these are reclassified as N. corylopsidis and N. hamamelidis. Taxonomic descriptions, illustrations, and a key to rust fungal species occurring in Hamamelidaceae in Asia are provided.

“…The Desmella clade was sister to Sphaerophragmiaceae sensu Beenken (2017) in the phylogenetic analyses based on the 28S rDNA region sequences (Fig. 1), while D. aneimiae was included in Pucciniaceae in phylogenetic analyses using the 28S, 18S rDNA and CO3 gene coding regions, e.g., Aime & McTaggart (2021). In the phylogram using the 28S region by McTaggart, Geering and Shivas (2014), D. aneimiae which was the same collection examined by Aime and McTaggart (2021) Desmella aneimiae is characterized by suprastomatal uredinia and telia (wardia-type) and diorchidioid teliospores, i.e., 2-celled pedicellate teliospores with vertical or oblique septa.…”

Rust fungi are biotrophic plant parasites. Individual rust species parasitize a variety of plants of lycopods, ferns, gymnosperms, and angiosperms, with narrow host preference. The rust fungi are classified in the order Pucciniales in the Pucciniomycotina of Basidiomycota and comprise about 7,800 species, 166 genera and 14 families worldwide (Kirk, Cannon, Minter, & Stalpers, 2008). Additionally, Aime and McTaggart (2021) proposed 18 families including seven new families and four new genera, newly proposing four new suborders based on phylogenetic analyses of a wide range of rust fungi using the 28S, 18S rDNA and cytochrome c-oxidase subunit 3 (CO3) gene of the mitochondrial DNA sequences.One early hypothesis about rust fungus evolution was that early divergent rust genera and species occur on early divergent host family and genera due to coevolution of rusts and their hosts (Cunning-

Melampsora larici-populina is an obligate biotrophic plant pathogen responsible for the poplar rust disease. This fungus belongs to the taxonomical order Pucciniales and exhibits a complex heteroecious and macrocyclic life cycle, i.e. it has the capacity to infect two unrelated host plants, larch and poplar, and to form five distinct spore types through the year. The M. larici-populina genome has been sequenced and annotated in 2011 and since, different transcriptomic analyses were conducted at different stages with oligoarrays and later on with RNA-Seq covering most of its life cycle. Here, we collected published transcriptome data for the poplar rust fungus, transposed them for the version 2 of the genome now available at the Joint Genome Institute Mycocosm website and performed normalization of different oligoarray datasets on one hand, and of RNA-Seq on the other hand. We report a comprehensive normalized dataset for this fungus, made available for the community, which allows life cycle transcriptomics analysis.
