“…Among them some species of the C. purpurea species group are unique by way of their host range. An extreme example is C. purpurea infecting various unrelated lineages of Pooideae or C. humidiphila and C. arundinis with hosts belonging to both to Arundinoideae and Pooideae (Negård et al 2015;Pažoutová et al 2015). The same is true for C. pazoutovae which was found on Ehrhartoideae as well as Pooideae.…”

“…The same is true for C. pazoutovae which was found on Ehrhartoideae as well as Pooideae. Consequently, the wide host spectrum of the whole species group includes all lineages of ergot hosts covering Arundinoideae, Chloridoidae, Cyperaceae, Ehrhartoideae, Pooideae, Panicoideae and Chloridoidae (Figure 1, Pažoutová et al 2015).…”

“…DNA was purified from 4-7-day old mycelium grown on T2 plates using an ArchivePure DNA Yeast & Gram± Kit (5 PRIME, Hamburg) as described in Pažoutová et al (2015). Nuclear rDNA containing internal transcribed spacers (ITS1 and ITS2), 5.8S and the 5′ end of the 28S region was amplified with primer pair ITS1F-KYO2/NL4 (ca 1.2 kbp) (Toju et al 2012, O'Donnell 1993.…”

“…Other recent examples of cryptic species or suspected cryptic plant pathogenic species include taxa potentially segregated from Monilinia vaccinii-corymbosi, a pathogen of blueberry (Vaccinium spp.) (Burchhardt and Cubeta 2015) and species within Claviceps purpurea, agent of ergot (Pažoutová et al 2015). Examples from natural environments include cryptic species within Lophodermium, needle-inhabiting fungi in Pinus spp., i.e., Lophodermium australe (Oono et al 2014) and L. pinastri (Reignoux et al 2014); and a potential cryptic species within Armillaria gallica, one of several agents of root disease of forest trees, especially conifers (Ross-Davis et al 2012).…”

Multiple traditional species names for plant pathogenic fungi have been supplemented with new names that delimit formerly cryptic species. In separate instances, isolates within a species are clearly differentiated by both phylogeny and distinctive pathogenic traits and are assigned sub-specific designations. These new species names and the sub-specific designations are both cases of cryptic species that are, in some instances, relevant and/or critical for plant disease management. Here we provide examples of such instances in which newly described taxa differ from the original ("parent") in phenotypic traits of importance to plant disease management: host range, fungicide sensitivity, environmental niche, metabolite production, regulatory status, or other attributes.

“…Multigene studies have confirmed this in C. purpurea s.l. with evidence pointing towards adaptation to ecological niches, and division into 8 different lineages (Pažoutová et al 2000, 2002, 2015; Douhan et al 2008; Shoukouhi et al 2019; Liu, M et al Submitted ). However, these cryptic species contain overlapping host ranges, geographic distributions, and alkaloid production.…”

1 2 Genus-wide comparison reveals divergence and evolution of the four sections within the 3 genus Claviceps are the result of varying mechanisms driving genome evolution and host 4 range 5 6 Abstract: 16 Background: 17 The genus Claviceps has been known for centuries as an economically important fungal 18 genera for pharmacology and agricultural research. Despite this little is known about its 19 evolution. Only recently have researchers begun to unravel the evolutionary history of the genus, 20 with origins in South America and classification of four distinct sections through ecological, 21 morphological, and metabolic features (Claviceps sects. Citrinae, Paspalorum, Pusillae, and 22 Claviceps). The first three sections are additionally characterized by narrow host range, while 23 sect. Claviceps is considered evolutionarily more successful and adaptable as it has the largest 24 host range and biogeographical distribution. However, the reasons for this success and 25 adaptability remain unclear.26Results: 27 Our study elucidates these factors by sequencing and annotating 50 Claviceps genomes, 28 representing 21 species, for a comprehensive comparison of genome architecture and plasticity 29 in relation to host range potential. Our results show the trajectory from specialized one-speed 30 genomes (C. sects. Citrinae and Paspalorum) to adaptive two-speed genomes (C. sects. Pusillae 31 and Claviceps) through co-localization of TEs around predicted effectors and loss of RIP 32 resulting in unconstrained tandem gene duplication coinciding with increased host range 33 potential and speciation.34 Conclusions: 35 Alterations of genomic architecture and plasticity can substantially influence and shape 36 the evolutionary trajectory of fungal pathogens and their adaptability. Furthermore, our study 37 provides a large increase in available genomic resources to propel future studies of Claviceps in 38 pg. 3 pharmacology and agricultural research, as well as, research into deeper understanding of the 39 evolution of adaptable plant pathogens. 40 41
