Poornima S., Rajivgandhi G., Maruthupandy M., Mothana R.A., Noman A.M., Nasr F.A., Ponmurugan P., Moorthy I.G. & Sivarajasekar N. (2022): Statistical modeling and optimization for the production of secondary metabolites by lichen mycobiont isolated from Parmotrema austrosinense - Physiological and Molecular Plant Pathology, 117: 101760 [6 p.]

Lichens produce range of secondary metabolites which exhibit multifarious biological potential. The present work highlights the effect of media components for the production of secondary metabolites by lichen Parmotrema austrosinense. Mycobiont was isolated by lichen tissue culture method. One variable at a time approach exhibited that, Malt yeast extract media supplemented with glucose (4 mg/L), asparagine (1 mg/L), MnSO4 4H2O (20 mg/L), ZnSO4 7H2O (20 mg/L) and H3BO3 (4 mg/L) enhanced the … Read more...

Aranibar J.N., Repetur M.J., García V.R., Dazat R.E., Corvalán Videla M.E. & Villagra P.E. (2022): Functional responses of biological soil crusts to simulated small precipitation pulses in the Monte desert, Argentina - Geoderma, 410: 115660 [8 p.]

In arid areas, biological activity responds to precipitation pulses, with different activation thresholds for different organisms. Biocrusts, communities of cyanobacteria, green algae, lichens and mosses living in the soil surface, contribute to soil fertilization by fixing atmospheric nitrogen (N), carbon (C), and solubilizing phosphorus (P). In this study, we hypothesized that biocrusts respond to low simulated precipitation pulses, lower than 10 mm, increasing nutrient availability. We expected … Read more...

Jiang S.-H., Lücking R., Liu H.-J., Wei X.-L., Xavier-Leite A.B., Portilla C.V., Ren Q. & Wei J.-C. (2022): Twelve new species reveal cryptic diversification in foliicolous lichens of Strigula s.lat. (Strigulales, Ascomycota) - Journal of Fungi, 8(1): 2 [30 p.]

We employed a molecular phylogenetic approach using five markers (ITS, nuSSU, nuLSU, TEF1-α, and RPB2) to assess potential cryptic speciation in foliicolous members of Strigula s.lat. (Strigulaceae), including the recently segregated genera Phylloporis, Puiggariella, Raciborskiella, Racoplaca, and Serusiauxiella, from tropical areas in Asia, with selected materials from the Neotropics as reference. On the basis of combined molecular and phenotypic datasets, two new species of Racoplaca and 10 new … Read more...

(2022): Elemental analysis and in vitro evaluation of antibacterial and antifungal activities of Usnea barbata (L.) Weber ex F.H. Wigg from Călimani Mountains, Romania - Plants, 11: 32 [21 p.]

This study aims to complete our research on Usnea barbata (L.) Weber ex F.H. Wigg (U. barbata) from the Calimani Mountains, Romania, with an elemental analysis and to explore its antibacterial and antifungal potential. Thus, we analyzed twenty-three metals (Ca, Fe, Mg, Mn, Zn, Al, Ag, Ba, Co, Cr, Cu, Li, Ni, Tl, V, Mo, Pd, Pt, Sb, As, Pb, Cd, and Hg) in dried U. barbata lichen (dUB) by inductively coupled plasma mass spectrometry (ICP-MS). For the second study, we performed dried lichen extraction … Read more...

Shanmugam K., Srinivasan M. & Neelakantan H.G. (2022): Insights into in vitro phenotypic plasticity, growth and secondary metabolites of the mycobiont isolated from the lichen Platygramme caesiopruinosa - Archives of Microbiology, 204: 90 [16 p.]

The choice of inoculum for successful isolation and establishment of axenic lichen mycobiont culture is a key step towards eliminating endolichenic and lichenicolous fungi and other microbial contamination. The nutritional requirements of each lichen species are unique. This work reports on the isolation, phenotypic plasticity, growth and secondary metabolites from mycobiont culture of the pantropical lichen Platygramme caesiopruinosa. Media composition [Malt yeast extract (MY), Modified Murashige … Read more...

Vijayakumar V.R., Saravanan K., Somasundaram M., Jayaraj R., Annamalai P., Nooruddin T. & Dharumadurai D. (2022): Metagenomic analysis of lichen‑associated bacterial community profiling in Roccella montagnei - Archives of Microbiology, 204: 54 [10 p.]

A lichen is a composite organism formed of algae or cyanobacteria that live in a mutually advantageous symbiotic relationship with the filaments (hyphae) of fungus. Three lichen samples were obtained from diverse sites at a terrestrial habitat located in Coimbatore and coastal habitats located in Kanyakumari and Nagapattinam districts of Tamil Nadu. Amplification and sequencing of 16S rRNA V3–V4 regions were used for metagenomic study. Aside from the Next-Generation Sequencing data (NGS), distinct … Read more...

Anderson J., Lévesque N., Caron F., Beckett P. & Spiers G.A. (2022): A review on the use of lichens as a biomonitoring tool for environmental radioactivity - Journal of Environmental Radioactivity, 243: 106797 [23 p.]

Lichens have been widely used as a biomonitoring tool to record the distribution and concentration of airborne radioactivity and pollutants such as metals. There are limitations, however: although pollutants can be preserved in lichen tissues for long periods of time, not all radioactive and inert elements behave similarly. The chemical species of elements at the source, once captured, and the mode of storage within lichens play a role in this biomonitoring tool. Lichens are a symbiotic association … Read more...

Stovall M.S., Ganguli A.C., Schallner J.W., Faist A.M., Yu Q. & Pietrasiak N. (2022): Can biological soil crusts be prominent landscape components in rangelands? A case study from New Mexico, USA - Geoderma, 410: 115658 [14 p.]

To sustainably manage rangelands, it is paramount that all agents of soil health are considered in conservation practices. Yet, our understanding of the extent and importance of biological soil crust (hereafter biocrust) as a component of rangeland health and quality is limited. The objective of this project was to quantify and characterize rangeland biocrusts within a region of New Mexico, USA, for which soil microbes have yet to be considered in rangeland health assessments: the Rio Puerco … Read more...

Blázquez M., Hernández-Moreno L.S., Gasulla F., Pérez-Vargas I. & Pérez-Ortega S. (2022): The role of photobionts as drivers of diversification in an island radiation of lichen-forming fungi - Frontiers in Microbiology, 12: 784182 [15 p.]

Speciation in oceanic islands has attracted the interest of scientists since the 19th century. One of the most striking evolutionary phenomena that can be studied in islands is adaptive radiation, that is, when a lineage gives rise to different species by means of ecological speciation. Some of the best-known examples of adaptive radiation are charismatic organisms like the Darwin finches of the Galapagos and the cichlid fishes of the great African lakes. In these and many other examples, … Read more...
