“…The overall data also showed that plants of the E. urophylla × E. grandis clone and E. globulus seed-derived plants had similar levels of susceptibility to most of the tested isolates (Fig. 12) Analysis of multi-gene phylogenetic concordance has emerged as standard practice for species identification in the Botryosphaeriaceae (Phillips et al 2013;Chen et al 2014aChen et al , 2014bSlippers et al 2017;Yang et al 2017;Li et al 2018;Jayawardena et al 2019aJayawardena et al , 2019bPhillips et al 2019).

The Botryosphaeriaceae accommodates many important pathogens of woody plants, including Eucalyptus. Recently, Botryosphaeriaceae were isolated from diseased plant parts from surveys of Eucalyptus plantations in the YunNan Province, China. The aims of this study were to identify these Botryosphaeriaceae isolates and to evaluate their pathogenicity to Eucalyptus. A total of 166 isolates of Botryosphaeriaceae were obtained from six regions in the YunNan Province, of which 76 were from Eucalyptus urophylla × E. grandis hybrids, 49 from E. globulus trees, and 41 isolates were from other unknown Eucalyptus species or hybrids. Isolates were identified by comparing DNA sequences of the internal transcribed spacer ribosomal RNA locus (ITS), partial translation elongation factor 1-alpha (tef1), β-tubulin 2 (tub2) and DNA-directed RNA polymerase II subunit (rpb2) genes, and combined with their morphological characteristics. Eleven species were identified, including Botryosphaeria fusispora, B. wangensis, Lasiodiplodia pseudotheobromae, Neofusicoccum kwambonambiense, N. parvum, and six novel species described as B. puerensis, N. dianense, N. magniconidium, N. ningerense, N. parviconidium and N. yunnanense. The dominant species across the regions were N. yunnanense, N. parvum and B. wangensis, representing 31.3, 25.3 and 19.9% of the total isolates, respectively. Species diversity and composition changed across the different climatic zones, despite their relatively close geographic proximity and the fact that some of the species have a global distribution. All the Botryosphaeriaceae species were pathogenic to one-year-old plants of an E. urophylla × E. grandis clone and E. globulus seed-derived plants, but showed significant inter- and intra-species variation in aggressiveness amongst isolates. The study provides a foundation for monitoring and management of Botryosphaeriaceae through selection and breeding of Eucalyptus in the YunNan Province of southwestern China.

“…However, Crous et al (2017) and Wijayawardene et al (2018a) accepted nine families including the above in Botryosphaeriales. Phillips et al (2019) then used a polyphasic approach (morphological studies, phylogenetic analyses and evolutionary study) and synonymized Endomelanconiopsisaceae, Pseudofusicoccumaceae and Septorioideaceae under Botryosphaeriaceae, Phyllostictaceae and Saccharataceae, respectively.…”

“…In order to avoid the confusions related to monospecific families some taxonomists have placed monospecific genera such as Pseudoxylomyces under Dothideomycetes genera incertae sedis rather than introducing new families (Ariyawansa et al 2015a, b). In another approach to addressing this problem, Phillips et al (2019) employed the morphology of sexual morph, phylogenetic relationships and evolutionary divergence times of lineages in relation to major events in the evolution of their hosts on a geological timescale for the re-assessment of families in Botryosphaeriales. Following the same integrative approach, Lücking (2019) proposed to use comparative phenotype divergence combined with branch length pattern analysis, in order to reflect the individual evolutionary history of higher-level taxa.…”

The fungal kingdom is estimated to comprise between 2.2 to 3.8 million species with only about 7% named and classified. Novel biochemical, physiological and molecular techniques have been utilized to improve the systematics of fungal taxa and estimates of their diversity. Multidisciplinary approaches should be used for resolving species and higher taxa of the fungi. However, even with all the benefits of the new techniques, they are also providing unclear results and taxonomic instability. Taxonomists should be aware of these issues and should follow pragmatic approaches. In order to overcome these taxonomic challenges, cooperation and communication among mycologists worldwide are crucial for the study of fungal diversity.

Mating-type locus rearrangement leads to shift from homothallism to heterothallism inCitrus-associatedPhyllostictaspecies

27Currently, eight Phyllosticta species are known to be associated with Citrus hosts, 28 incorporating endophytic and pathogenic lifestyles. As sexual reproduction is a key factor 29 involved in host-interaction, it could be related to the differences in lifestyle. To evaluate this 30 hypothesis, we characterized the mating-type loci of six Citrus-associated Phyllosticta species 31 from whole genome assemblies. Mating-type genes are highly variable in their sequence 32 content, but the genomic locations and organization of the mating-type loci are conserved. 33Phyllosticta citriasiana, P. citribraziliensis and P. paracitricarpa are heterothallic, and P. 34 citrichinaensis was confirmed to be homothallic. In addition, the P. citrichinaensis MAT1-2 35 idiomorph occurs in a separate location from the mating-type locus. Ancestral state 36 reconstruction suggests that homothallism is the ancestral thallism state in Phyllosticta, with a 37 shift to heterothallism in Phyllosticta species that are pathogenic to Citrus. Moreover, the 38 homothallic strategies of P. capitalensis and P. citrichinaensis result from independent 39 evolutionary events. As the pathogenic species P. citriasiana, P. citricarpa and P. 40 paracitricarpa are heterothallic and incapable of selfing, disease management practices 41 focused in preventing the occurrence of sexual reproduction could assist in the control of 42Citrus Black Spot and Citrus Tan Spot diseases. This study emphasizes the importance of 43 studying Citrus-Phyllosticta interactions under evolutionary and genomic perspectives, as 44 these approaches can provide valuable information about the association between Phyllosticta 45 species and their hosts, and also serve as guidance for the improvement of disease 46 management practices. 47 48
