Wang S., Li W., Wufuer R., Duo J., Pei L. & Pan X. (2023): The key role of cyclic electron flow in the recovery of photosynthesis in the photobiont during rehydration of the lichen Cladonia stellaris, Plants, 12(23): 4011 [14 p.]

Lichens are poikilohydric organisms and an important part of the ecosystem. They show high desiccation tolerance, but the mechanism of dehydration resistance still needs to be studied. The photosynthesis recovery of the photobiont in rehydrated lichen Cladonia stellaris after 11-year desiccation was investigated by simultaneously monitoring both photosystem I and II (PSI and PSII) activities. The responses of the photochemical efficiency and relative electron transport rate (rETR) of PSI and … Read more...

Wang S., Zang J., Huang M., Guan L., Xing K., Zhang J., Liu D. & Zhao L. (2019): Discovery of novel (+)-usnic acid derivatives as potential anti-leukemia agents with pan-pim kinases inhibitory activity, Bioorganic Chemistry, 89: 102971

Usnic acid (UA) is the main secondary metabolite isolated from lichens, with moderate anticancer activity. A small group of (+)-UA derivatives characterized with flavanone moiety was designed and synthesized, and their anticancer activities were evaluated in leukemia cells. It was demonstrated that (+)-UA derivatives 6a–6g inhibited the proliferation of leukemia cells HL-60 and K562 with low micromolar IC50 values. Mechanisms of action were investigated to find that 6g induced apoptosis in HL-60 … Read more...

Wang S., Zhao G., Niu D., Wang L., Ren X., Wu J. & Qu H. (2024): Three new species and a new record of the lichen genus Peltula (Peltulaceae) from Helan Mountain in China, Biology, 13(8): 590 [15 p.]

In this study, a systematic taxonomic analysis was carried out on the lichen genus Peltula, collected from Helan Mountain in China; three new species (Peltula helanense, P. overlappine, and P. reticulata) and a new record (P. crispatula (Nyl.) Egea) for China were identified. Four species were identified by morph-anatomical, chemical, and phylogenetic analyses by combining two gene loci (ITS and LSU). Peltula helanense is with tiny individual thalli up to 1mm, attached by creamy-white cylindrical … Read more...

Wang T., Shen C., Guo F., Zhao Y., Wang J., Sun K., Wang B., Chen Y. & Chen Y. (2021): Characterization of a polysaccharide from the medicinal lichen, Usnea longissima, and its immunostimulating effect in vivo, Int. J. Biol. Macromol., 181: 672-682

A polysaccharide, CSL-0.1, was isolated from the medicinal lichen, Usnea longissima. CSL-0.1 was a neutral rhamnose-containing glucogalactomannan with a molecular weight of 7.86 x 10(4) Da. The polysaccharide had a core mannan structure with (1 --> 6)-alpha-d-Manp units as the main chain and was substituted at the O-2 positions with side chains containing (1 --> 2)-alpha-d-Manp residue, [3)-alpha-Glcp(1 --> 4)-alpha-Glcp(1-->] and 6-O-substituted beta-d-Galf units. 2-O- and 2,3-di-O-substituted Rhap … Read more...

Wang W. (2025): Fellhaneropsis sigmoidea sp. nov. (Byssolomataceae, lichenized Ascomycota), a new foliicolous species from China, with a world key to the species of the genus Fellhaneropsis, The Lichenologist, 57(5): 200-205

A new species of the lichenized genus Fellhaneropsis is described from China. Fellhaneropsis sigmoidea W. C. Wang & J. C. Wei is characterized by a dispersed thallus, brown apothecia with an indistinct margin, 3-septate ascospores (14–20 μm in length), filiform-sigmoid conidia, and a foliicolous growth habit. The placement of the new species within Fellhaneropsis was confirmed by a molecular phylogenetic approach based on mtSSU sequence data. A world key to the species of the genus Fellhaneropsis … Read more...
