Zhou J. & Ren Q. (2018): Varicellaria emeiensis sp. nov. and a review of the genus in China - Mycotaxon, 133(1): 71–77

A new species, Varicellaria emeiensis, is described from Sichuan Province, southwest China. It is characterized by its lecanorate apothecia with heavily white-pruinose discs, 8-spored ascus, and the presence of lecanoric acid. Additional material is reported for four Varicellaria species previously recorded from China, and a key is provided to the five species known from China. Key words—Ochrolechiaceae, Pertusariales, lichens, taxonomy. Read more...

Zhou Q.-M. & Wei J.-C. (2007): A New Order Umbilicariales J.C. Wei & Q.M. Zhou (Ascomycota) - Mycosystema, 26(1): 40-45

The phylogenetic position of the lichen family Umbilicariaceae is investigated using nucleotide sequences of the nuclear SSU rDNA region. Sequences of 6 species were obtained in this study and aligned to those of other lichenized and non-lichenized fungal species from GenBank. The result indicates that the Umbilicariaceae cannot be included in the order Lecanorales and the order Umbilicariales is supported by both the molecular and morphological data. The new order Umbilicariales within Lecanoromycetes, … Read more...

Zhou Q.-M., Guo S.-Y., Huang M.-R. & Wei J.-C. (2006): A study of the genetic variability of Rhizoplaca chrysoleuca using DNA sequences and secondary metabolic substances - Mycologia, 98(1): 57–67

Specimens of Rhizoplaca chrysoleuca from Mount Wuling can be divided into two distinct groups based on obvious differences in morphological characters. Here we investigated 26 specimens of R. chrysoleuca from Mount Wuling, 10 specimens of this species from other areas and seven specimens of other Rhizoplaca species by analyzing morphology, chemistry and genetics. Nine chemotypes were detected among the specimens of R. chrysoleuca from Mount Wuling, and five of them were reported for the first time. … Read more...

Zhou Q.-M., Wei J.-C., Ahti T., Stenroos S. & Högnabba F. (2006): The systematic position of Gymnoderma and Cetradonia based on SSU rDNA sequences - Journal of the Hattori Botanical Laboratory, 100: 871-880

Phylogenetic relationships of Gymnodenna coccocarpum and Cetradonia linearis were investigated using nucleotide sequence data of the SSU rDNA. Our results show that Gymnodenna and Cetradonia form a clade, which is a sister group of Pycnothelia and Carassea. As a result, both Gynmoderma and Cetradonia are clearly members of the family Cladoniaceae and the family name Cetradoniaceae has to be abandoned. The SSU rDNA of Gymnoderma contains seven group I and one spliceosomal intron, the positions and … Read more...

Zhou R., Yang R. & Jing C. (2018): Polycyclic aromatic hydrocarbons in soils and lichen from the western Tibetan Plateau: Concentration profiles, distribution and its influencing factors - Ecotoxicology and Environmental Safety, 152: 151–158

The Tibetan Plateau (TP) is a huge area and rarely affected by human activity, and is regarded as one of the most remote regions on the earth. Many studies about the long-range atmospheric transport (LRAT) of semi-volatile organic compounds (SVOCs) were conducted in southern and central TP. However, there are very limited studies focused on PAHs in the western TP and the concentrations profiles, distribution and its controlling factors in this area remains unclear. Thus, to explore this knowledge … Read more...

Zhou R., Yang Y., Park S.-Y., Nguyen T.T., Seo Y.-W., Lee K.H., Lee J.H., Kim K.K., Hur J.-S. & Kim H. (2017): The lichen secondary metabolite atranorin suppresses lung cancer cell motility and tumorigenesis - Scientific Reports, 7:8136 [13 p.]

Lichens are symbiotic organisms that produce various secondary metabolites. Here, different lichen extracts were examined to identify secondary metabolites with anti-migratory activity against human lung cancer cells. Everniastrum vexans had the most potent inhibitory activity, and atranorin was identified as an active subcomponent of this extract. Atranorin suppressed β-catenin-mediated TOPFLASH activity by inhibiting the nuclear import of β-catenin and downregulating β-catenin/LEF and c-jun/AP-1 … Read more...

Zhou R., Zhang L., Zeng B., Zhou Y., Jin W. & Zhang G. (2023): A novel self‑purifed auxiliary protein enhances the lichenase activity towards lichenan for biomass degradation - Applied Microbiology and Biotechnology , 107: 4553–4566

Due to the complex composition of lichenan, lichenase alone cannot always hydrolyze it efciently. Carbohydrate-binding modules (CBMs) and lytic polysaccharide monooxygenases (LPMOs) have been confrmed to increase the hydrolysis efciency of lichenases. However, their practical application was hampered by the complex and costly preparation procedure, as well as the poor stability of LPMOs. Herein, we discovered a novel and stable auxiliary protein named SCE to boost the hydrolysis efciency. … Read more...

Zhou X., Zhao Y., Belnap J., Zhang B., Bu C. & Zhang Y. (2020): Practices of biological soil crust rehabilitation in China: experiences and challenges - Restoration Ecology, 28(S2): 45–55

Biological soil crusts (biocrusts) are a central component of dryland ecosystems.However, they are highly vulnerable to disturbance and natural recovery may be slow. Therefore, finding ways to enhance the reestablishment of biocrusts after disturbance has been of great interest to researchers. This article provides a review of the laboratory cultivation and field inoculations of biocrust materials in China (mostly published in Chinese). Larger filamentous cyanobacteria (e.g. Microcoleus) are relatively … Read more...

Zhou X.B., Zhang Y.M. & Yin B.F. (2016): Divergence in physiological responses between cyanobacterial and lichen crusts to a gradient of simulated nitrogen deposition - Plant and Soil, 399: 121–134

Background and aims: Nitrogen (N) deposition in arid lands is known to be increasing. However, N deposition gradients have unclear effects on physiological characteristics of biocrusts. This study tested if physiological characteristics are stimulated by low levels of N deposition and reduced by high levels of N deposition. Methods We simulated N deposition at various rates to plots of cyanobacterial and lichen biocrusts in the Gurbantunggut Desert and measured indicators of growth and stress. Results … Read more...
