Resolving the phylogenetic position of Caeoma spp. that infect Rhododendron and Chrysomyxa from China

Phylogeny and biogeography of the Japanese rhinoceros beetle, Trypoxylus dichotomus (Coleoptera: Scarabaeidae) based on SNP markers

“…Default parameters were selected, and the evolutionary model was set to the GTR + I + G model, which was the best model predicted for the concatenated 16S and COII alignment by MrModeltest v. 2.3 (Nylander, 2004). Simultaneous Markov chains were computed for 1,000,000 generations, and the trees were sampled every 100th generation (You et al., 2019).…”

“…Default parameters were selected, using a GTR (general time reversible) substitution model with gamma‐distributed rate variation across sites and a proportion of invariable sites (Ronquist & Huelsenbeck, 2003). Simultaneous Markov chains were run for 1,000,000 generations, and with sampling every 100th generation (You et al., 2019).…”

Cryptic Species Diversity and Phylogenetic Relationship in the Rust Genus Chrysomyxa from China

“…Rust fungi of the genus Chrysomyxa Unger (Coleosporiaceae, Pucciniales) are widespread in the Northern hemisphere, causing spruce needle and cone rust diseases, which are responsible for significant economic losses, especially in spruce plantations and natural forests in northwest and southwest China [12][13][14][15][16]. Most Chrysomyxa species are heteroecious, macrocyclic and they produce the spermogonia and aecia on Pinaceae, while also the uredinia and telia on Ericaceae and Pyrolaceae, mostly on Rhododendron [2,4,12,15,16]. The monophyly of Chrysomyxa was supported by LSU sequence data from two closely related Chrysomyxa species (Chrysomyxa ledi and C. rhododendri) [17].…”

“…The species delimitation of Chrysomyxa has been controversial as several species display similar morphological features; the traditional identification is mainly based on host specificities and morphological characteristics of each spore stage [12,15,16,18]. For example, C. rhododendri on Rhododendron in Europe and C. ledi on Ledum in North America have subtle morphological and ecological traits, but they have distinct host specificities [15,19].…”
