Peptides are a particular molecule class with inherent attributes of some small-molecule drugs and macromolecular biologics,thereby inspiring continuous searches for peptides with therapeutic and/or agrochemical potentials.However,the success rate is decreasing,presumably because many interesting but less-abundant peptides are so scarce or labile that they are likely‘overlooked’during the characterization effort.Here,we present the biochemical characterization and druggability improvement of an unprecedented minor fungal RiPP(ribosomally synthesized and post-translationally modified peptide),named acalitide,by taking the relevant advantages of metabolomics approach and disulfide-bridged substructure which is more frequently imprinted in the marketed peptide drug molecules.Acalitide is biosynthetically unique in the macrotricyclization via two disulfide bridges and a protease(AcaB)-catalyzed lactamization of AcaA,an unprecedented precursor peptide.Such a biosynthetic logic was successfully re-edited for its sample supply renewal to facilitate the identification of the in vitro and in vivo antiparkinsonian efficacy of acalitide which was further confirmed safe and rendered brain-targetable by the liposome encapsulation strategy.Taken together,the work updates the mining strategy and biosynthetic complexity of RiPPs to unravel an antiparkinsonian drug candidate valuable for combating Parkinson’s disease that is globally prevailing in an alarming manner.

Three new species of Hypomyces from China

Two new species of Geejayessia（Hypocreales） from Asia as revealed by morphology and multi-gene analyses

中国菌物学会2015年学术年会

作者： Zhao-Qing Zeng wen-ying zhuang State Key Laboratory of Mycology Institute of MicrobiologyChinese Academy of Sciences

The genus Hypomyces contains a large number species exclusively growing on other fungi. In the past, many fungicolous fungi producing light or bright-colored perithecia associated with subiculum were treated as "Hypomyces". The generic concept became increasingly broad. More than 200 names were created under the genus. According to modern taxonomic treatments, 68 species are commonly accepted. The genus is characterized by ascomata superficial on or immersed in subiculum, perithecial wall generally less than 25 μm thick, asci cylindrical, 8-sproed, apex thickened with a distinct pore, and ascospores ellipsoid, lanceolate with rounded ends, or fusiform with an apiculus at each end, non- or 1-septate, hyaline, smooth, spinulose to verrucose. According to the International Code of Nomenclature for algae, fungi and plants, the sexual state name Hypomyces is recommended as preferable over the asexual state names, i.e. Cladobotryum, Mycogone, Sepedonium and Stephanoma. Members of the genus are worldwide distributed, mainly in temperate and tropical regions, and as parasites of Agaricales, Boletales, Helotiales, Pezizales and Polyporales. The early records of Hypomyces from China date back to 1934 when H. aurantius, H. chrysospermus and H. hyalinus on fruitbodies of polypores and agaricaceous fungi were reported by S.C. Teng. Twelve species were later reported from the mainland. Hypomyces succineus and H. chlorinigenus were listed in Taiwan Digitalarchives（http://catalog.***.tw）. Till now, 17 species of the genus were known from China. In connection with our current work on the Chinese Fungus Flora, especially on Hypocreaceae, recent collections and herbarium specimens from different regions were examined. Three new species are discovered based on materials from Yunnan Province. Hypomyces amaniticola is characterized by perithecia aggregated, semi-immersed to immersed in subiculum, oval to pyriform, orange yellow to brownish yellow;cylindrical asci 8-spored;and ascospores fusiform to ellipsoid, unicellular,

Three-locus phylogeny of Gyromitra（Discinaceae, Pezizales）and discovery of two cryptic species

中国菌物学会2018年学术年会

作者： Zhao-Qing Zeng wen-ying zhuang State Key Laboratory of Mycology Institute of MicrobiologyChinese Academy of Sciences

The genus Geejayessia is characterized by prosenchymatous stromata erumpent through substrates,caespitose, broadly pyriform, pale orange, brownish to reddish orange, bright red to black perithecia;cylindrical or clavate asci with eight ascospores;broadly ellipsoidal to ellipsoidal ascospores that are uniseptate, slightly constricted at the septum, hyaline or pale brown to yellowish brown, smooth or verruculose at maturity;and multiseptate, slightly curved macroconidia with conspicuous pedicellate foot cell. Members of Geejayessia exhibit host specificity and mainly occur on Buxus spp., Celtis occidentalis and Staphylea trifolia, and were reported only from Europe, North America and Oceania.In our examinations of nectriaceous collections from Henan and Hubei provinces, two cosmospora-like fungi were encountered. Judging by perithecial gross morphology, anatomic structures and culture characteristics, they represent two previously undescribed species of Geejayessia. Their taxonomic placements are confirmed by analyses of the combined larger subunit of the ATP citrate lyase（ACL1）, internal transcribed spacer of nuclear ribosomal DNA（ITS）, and the second largest subunit of the RNA polymerase II（RPB2） sequences. Distinctions between the new species and their closely related fungi are discussed. The new species discovered from central China extends the distribution of the genus to Asia.

Towards a natural classification of Botryosphaeriales

中国菌物学会2018年学术年会

作者： Xin-Cun Wang wen-ying zhuang State Key Laboratory of Mycology Institute of MicrobiologyChinese Academy of Sciences

Gyromitra is known as ‘false morels’ and produces cerebriform or discoid ascocarps. It is widely distributed in the northern hemisphere and some species of the genus are poisonous. The intrageneric phylogeny based on LSU was reported, however, molecular analysis derived from other genes is lacking. In this study,Gyromitra specimens deposited in HMAS were re-examined. Phylogenies of the group inferred from LSU, ITS and tef1 were obtained, and four clades were revealed among 13 species. Two cryptic species of Gyromitra, G.pseudogigas sp. nov. and G. tianshanensis sp. nov., are described. Gyromitra pseudogigas has saddle-shaped apothecia similar to G. infula and is sister to G. gigas in the phylogeny. Gyromitra tianshanensis clusters with G.infula and G. xinjiangensis but differs in morphology and sequence data.

Paper-based sensing platform is a point of need analytical toolkit for safety testing.However,the sensitivity,specificity,and simplicity are still challenging.Herein,we report a novel strategy(Au/δ-MnO_(2) hollow nanosphere and 3,3′,5,5′-tetramethylbenzidine(TMB)induced test strips for signal-on detection)that can be utilized for hexavalent chromium(Cr^(6+))detection.Interestingly,Cr^(6+)(CrO_(4)^(2−)) as a smart switch can remarkably enhance the oxidase-like activity of Au/δ-MnO_(2) hollow nanosphere.The presence of Cr^(6+) can regulate the surface electronic redistribution of Au/δ-MnO_(2) and adjust the geometric configuration,which leads to the improvement in oxidase-like activity of Au/δ-MnO_(2).As a proof-of-concept application,a visual paper-based sensing platform of Cr^(6+) along with quantitative analysis by the test strips was successfully constructed.This paper-based sensing platform exhibits a linear range with excellent selectivity for other interfering substances and lower limit of detection of 0.09μmol·L^(−1),providing a promising toolkit at-home Cr^(6+) measurement and environmental monitoring.

The perforating phase leads to complex and diverse hydraulic fracture propagation behaviors in laminated shale formations. In this paper, a 2D high-speed imaging scheme which can capture the interaction between perforating phase and natural shale bedding planes was proposed. The phase field method was used to simulate the same conditions as in the experiment for verification and hydraulic fracture propagation mechanism under the competition of perforating phase and bedding planes was discussed.The results indicate that the bedding planes appear to be no influence on fracture propagation while the perforating phase is perpendicular to the bedding planes, and the fracture propagates along the perforating phase without deflection. When the perforating phase algins with the bedding planes, the fracture initiation pressure reserves the lowest value, and no deflection occurs during fracture propagation. When the perforating phase is the angle 45°, 60°and 75°of bedding planes, the bedding planes begin to play a key role on the fracture deflection. The maximum deflection degree is reached at the perforating phase of75°. Numerical simulation provides evidence that the existence of shale bedding planes is not exactly equivalent to anisotropy for fracture propagation and the difference of mechanical properties between different shale layers is the fundamental reason for fracture deflection. The findings help to understand the intrinsic characteristics of shale and provide a theoretical basis for the optimization design of field perforation parameters.
