The Lichens' Microbiota, Still a Mystery?
fmicb-12-623839 March 24, 2021 Time: 15:25 # 1 REVIEW published: 30 March 2021 doi: 10.3389/fmicb.2021.623839 The Lichens’ Microbiota, Still a Mystery? Maria Grimm1*, Martin Grube2, Ulf Schiefelbein3, Daniela Zühlke1, Jörg Bernhardt1 and Katharina Riedel1 1 Institute of Microbiology, University Greifswald, Greifswald, Germany, 2 Institute of Plant Sciences, Karl-Franzens-University Graz, Graz, Austria, 3 Botanical Garden, University of Rostock, Rostock, Germany Lichens represent self-supporting symbioses, which occur in a wide range of terrestrial habitats and which contribute significantly to mineral cycling and energy flow at a global scale. Lichens usually grow much slower than higher plants. Nevertheless, lichens can contribute substantially to biomass production. This review focuses on the lichen symbiosis in general and especially on the model species Lobaria pulmonaria L. Hoffm., which is a large foliose lichen that occurs worldwide on tree trunks in undisturbed forests with long ecological continuity. In comparison to many other lichens, L. pulmonaria is less tolerant to desiccation and highly sensitive to air pollution. The name- giving mycobiont (belonging to the Ascomycota), provides a protective layer covering a layer of the green-algal photobiont (Dictyochloropsis reticulata) and interspersed cyanobacterial cell clusters (Nostoc spec.). Recently performed metaproteome analyses Edited by: confirm the partition of functions in lichen partnerships. The ample functional diversity Nathalie Connil, Université de Rouen, France of the mycobiont contrasts the predominant function of the photobiont in production Reviewed by: (and secretion) of energy-rich carbohydrates, and the cyanobiont’s contribution by Dirk Benndorf, nitrogen fixation.

О находке галотолерантной водоросли Asteromonas gracilis Artari в Оренбургской области. – Немцева Н. В., Игнатенко М. Е. – Галотолератная водоросль Asteromonas gracilis Artari выделена из планктонного сообщества грязе-рапного озера Тузлучное, отно- сящегося к группе грязе-рапных озёр Соль-Илецкого курорта. Данный вид зеленой водо- росли отсутствует в списке альгофлоры Соль-Илецких водоёмов и является новым для тер- ритории Степного Предуралья. Морфология данной водоросли изучена с использованием световой фазово-контрастной микроскопии, представлены оригинальные фотографии. В ла- бораторных условиях выявлен диапазон галотолератности, подобран оптимальный режим культивирования. Экспериментально продемонстрировано наличие антилизоцимной и анта- гонистической активности у данной водоросли. Ключевые слова: галотолерантная водоросль, Asteromonas gracilis, антилизоцимная ак- тивность, антагонистическая активность. Discovery of halotolerant alga Asteromonas gracilis Artari from phitoplancton in the Orenburg region. – Nemtseva N. V. and Ignatenko M. E. – The halotolerant alga Asteromonas gracilis Artari was isolated from the planktonic association of the Tusluchnoye Lake, related to the group of salt lakes of the Sol-Iletsk resort. This type of green alga is absent in the algae vegetation list of the Sol-Iletsk reservoirs and is new for the Steppe Pre-Ural area. The morphological struc- ture of this alga was studied by means of phase-contrast microscopy (original photos are enclosed). The range of halotolerance was estimated and an optimum regime of cultivation was chosen in laboratory conditions. -
The Hawaiian Freshwater Algae Biodiversity Survey
Sherwood et al. BMC Ecology 2014, 14:28 http://www.biomedcentral.com/1472-6785/14/28 RESEARCH ARTICLE Open Access The Hawaiian freshwater algae biodiversity survey (2009–2014): systematic and biogeographic trends with an emphasis on the macroalgae Alison R Sherwood1*, Amy L Carlile1,2, Jessica M Neumann1, J Patrick Kociolek3, Jeffrey R Johansen4, Rex L Lowe5, Kimberly Y Conklin1 and Gernot G Presting6 Abstract Background: A remarkable range of environmental conditions is present in the Hawaiian Islands due to their gradients of elevation, rainfall and island age. Despite being well known as a location for the study of evolutionary processes and island biogeography, little is known about the composition of the non-marine algal flora of the archipelago, its degree of endemism, or affinities with other floras. We conducted a biodiversity survey of the non-marine macroalgae of the six largest main Hawaiian Islands using molecular and microscopic assessment techniques. We aimed to evaluate whether endemism or cosmopolitanism better explain freshwater algal distribution patterns, and provide a baseline data set for monitoring future biodiversity changes in the Hawaiian Islands. Results: 1,786 aquatic and terrestrial habitats and 1,407 distinct collections of non-marine macroalgae were collected from the islands of Kauai, Oahu, Molokai, Maui, Lanai and Hawaii from the years 2009–2014. Targeted habitats included streams, wet walls, high elevation bogs, taro fields, ditches and flumes, lakes/reservoirs, cave walls and terrestrial areas. Sites that lacked freshwater macroalgae were typically terrestrial or wet wall habitats that were sampled for diatoms and other microalgae. Approximately 50% of the identifications were of green algae, with lesser proportions of diatoms, red algae, cyanobacteria, xanthophytes and euglenoids. -

F06108 Nice cedex 02, France * Corresponding author: [email protected] With 5 figures in the text and an electronic supplement Abstract: Green algae (Chlorophyta) are an important group of microalgae whose diversity and ecological importance in marine systems has been little studied. In this review, we first present an overview of Chlorophyta taxonomy and detail the most important groups from the marine environment. Then, using public 18S rRNA Chlorophyta sequences from culture and natural samples retrieved from the annotated Protist Ribosomal Reference (PR²) database, we illustrate the distribution of different green algal lineages in the oceans. The largest group of sequences belongs to the class Mamiellophyceae and in particular to the three genera Micromonas, Bathycoccus and Ostreococcus. These sequences originate mostly from coastal regions. Other groups with a large number of sequences include the Trebouxiophyceae, Chlorophyceae, Chlorodendrophyceae and Pyramimonadales. Some groups, such as the undescribed prasinophytes clades VII and IX, are mostly composed of environmental sequences. The 18S rRNA sequence database we assembled and validated should be useful for the analysis of metabarcode datasets acquired using next generation sequencing. -

Jahanzeb College Swat, Pakistan 2Department of Biotechnology, Quaid-e-Azam University Islamabad, Pakistan 3Pakistan Museum of Natural History, Islamabad, Pakistan Abstract Fifty six genera of green algae were collected from ten different localities of District Swat, belonging to 25 families and 9 genera of Chlorophyta from December 2006 August 2008. Family Oocystaceae with 39 species was most commonly found, next to it were families Scenedesmaceae with18 species and Desmidiaceae with 14 species. The genera Oocystis and Tetraedron were represented by 10 species and Cosmarium with 7 species occurred most commonly. Among the recorded genera 13 (23.2%) were Unicellular, 25 (44.6%) were Colonial, 9 (16.7%) were Unbranched filamentous, 4 (7.1%) were branched filamentous, 1 (1.7%) was Pseudofilamentous, 1 (1.7%) was Mesh-like, 2 (3.5%) were Heterotrichous and 1 (1.7%) was with Irregular amorphous thallus. Highest proportion of Chlorophycean members was recorded from Kanju area 89 and lowest was recorded from Kalam 69. Introduction Results and Discussion The Valley of Swat a part of Malakand Division covers Fifty six genera containing 138 species belonging to 25 5737 square kilometers (estimated). The elevation of the families and 9 orders have been collected from various fresh valley is 630 to 3000m above sea level. Swat is located at a water habitats. Collected algal members were identified up to distance of 170 km from Peshawar and 270 km from Federal species level. -
