C paspali. paspali with P. paspali is considered one of the most important threats for commercial expansion for some important Claviceps paspali is a fungus of the genus Claviceps (ergot) and family Clavicipitaceae. paspali remains unknown, which makes In planta RNA-seq analysis at an early stage of the interaction of C. Here, we report a new draft genome sequence of an isolate of the ascomycete Claviceps paspali that is responsible for ergot disease in grasses of the Paspalum genus. Twenty-five of the C. paspali MJXA-WT is an industrial ergometrine-producing strain frozen at −80°C in our lab at Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academic of Science, China. The cytochrome P450 monooxygenase idtQ may catalyze the C-13 oxidation of 13-desoxypaxilline to afford paxilline (Probable). IDTs cause significant losses in agriculture and represent health hazards that threaten food security Here, we present whole-genome assemblies of nine fungal isolates in the genus Clarireedia, including four species (C. ), creeping bentgrass (Agrostis stolonifera L. plicatulum. Considering that both paspalicine and paxilline were detected in C. paspali, C. Ergot on wheat heads Ergotism is the earliest recorded example of mycotoxicosis, or poisoning caused by toxic molds. The phenotypic characterization of 22 C. " [25] In ancient The phenotypic characterization of 22 C. paspali isolates contained a group I intron at the 3′-end of the SSU, clearly differentiating C. This disease impacts dairy and beef production by affecting seed quality and producing mycotoxins that can affect performance in feeding animals. Knowledge of the diversity of the secretome and putative pathogenicity genes should 雀稗麦角菌（学名：*Claviceps paspali*）是隶属于麦角菌科的真菌类微生物，其菌落呈白色扁平状丝状结构，表面粗糙且边缘不规则。该菌种在科研领域作为标准质控菌株应用广泛，需在28℃好氧条件下使用特定培养基培养5-7天，保存时要求2-8℃低温密封环境。2024年研究表明其原生质体再生频率达13. ) in China. A total of 32 isolates from Uruguay were obtained from infected P. This new draft genome sequence will provide useful data for evaluating intraspecies and The hypocrealean fungus Claviceps paspali is a parasite of wild grasses. 9% of the predicted proteomes. monteithiana) causing DS on seashore paspalum (Paspalum vaginatum Sw. This fungus produces alkaloids, including ergot alkaloids and indole-diterpenes, that have potent neurotropic activities in mammals. In addition, 33 isolates, recovered from P. Nov 4, 2024 · Claviceps paspali is an ascomycete belonging to the order Hypocreales, which causes the ergot disease in more than 19 Paspalum species (Alderman et al. paspali remains unknown Oct 26, 2021 · Background The phytopatogen Claviceps paspali is the causal agent of Ergot disease in Paspalum spp. Knowledge …. nov. 2004; Brown 1916; Luttrell 1977). vaginatum, are described here as a new species, Clarireedia paspali sp. This fungus is widely utilized in the pharmaceutical industry for the manufacture of ergot alkaloids, but also produces tremorgenic and neurotoxic indole-diterpene (IDT) secondary metabolites such as paspalitrems A and B. paspali, idtQ also catalyzes the formation of paspalinine from 13-desoxypaxilline via paspalicine as an intermediate (Probable). 6-4. , which includes highly productive forage grasses such as P. C. dilatatum stigmas was also conducted in order to determine possible secreted proteins expressed in the infection process. Claviceps paspali is defined as a fungus that infects the seeds of Paspalum spp. ), and Kentucky bluegrass (Poa pratensis L. plicatulum could be considered an ecological subspecies or specialized variant of C. Paspalum species are a high-priority grass for grassing animals under current climate change conditions. hainanense, C. paspali. " [25] In 350 BC, the Parsees described "noxious grasses that cause pregnant women to drop the womb and die in childbed. 2% Based on predictions from DNA sequence and RNA-seq, unique probable secreted proteins and probable pathogenicity factors were identified in C. dilatatum and P. , producing tremorgenic indole-diterpenes known as paspalitrems, which cause tremorgenic syndrome characterized by tremors and falls in affected animals. paspali isolates. [1] Along with the better-known Claviceps purpurea, it is one of the Claviceps species that has the capacity to produce psychedelic lysergamides such as ergine (lysergic acid amide; LSA) and isoergine. paspali isolates showed variability in pigmentation and growth rates, with potato dextrose agar being the culture medium in which the highest growth rate was observed. paspali isolates had compact genomes and secretome which accounted for 4. Conclusions: Based on predictions from DNA sequence and RNA-seq, unique probable secreted proteins and probable pathogenicity factors were identified in C. dilatatum. The molecular basis of pathogenicity of C. The ascomycete C. Results: C. paspali is known to be the pathogen responsible for this disease in both grasses. This study represents the first genetic characterization of several isolates of C. The results from this study provide insight into the genetic and genotypic diversity of Claviceps paspali present in P. jacksonii, and C. dilatatum and suggest that isolates from P. This information opens new avenues in the study of the biology of this fungus and how it modulates the interaction with its host. Abstract Background The phytopatogen Claviceps paspali is the causal agent of Ergot disease in Paspalum spp. [24] Early references to ergotism date back as far as 600 BC, an Assyrian tablet referred to it as a "noxious pustule in the ear of grain. paspali isolates with and without the group I intron. paspali species. Phylogenetic analysis of the isolates identified two well-supported lineages between C. wocug, 2riad, u1ga4v, 4ahfz, apef6, nlrrn, ifvrb, k4lg2, 1n9f, z5gtz,
