Christian Leuckert
Christian Leuckert was a lichen taxonomist who applied the diversity of secondary metabolites within lichens as useful taxonomic criteria. He was Director of the Institute of Plant Systematics and Plant Geography at the Free University of Berlin from the 1970s until 1995. Early life and education Christian Leuckert's parents were Alfred and Louise (née Friedrich) Leuckert. His father worked as an expert plumber. After elementary school in Radeberg, he began attending a Rudolph Steiner school in Dresden, until it was officially closed in 1941. He completed his secondary education in Radeberg. After the Second World War he found himself in the German Democratic Republic. He was able to complete his education from 1946 - 1948 at the re-opened Steiner school. He then trained as a teacher at Technical University of Dresden and Martin Luther University in Halle-Wittenberg. In 1954 he was allowed to re-start his education, studying biology at University of Leipzig. However, in 1955 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radeberg
Radeberg is a small town in the district of Bautzen, Saxony, Germany. It is located approximately 20 kilometres north-east of Dresden. The town has an Evangelical and a Roman Catholic church, and an old castle. History Radeberg was mentioned for the first time in 1219, when farmers settled on the country to the large Roeder. The name of the place is probably derived from this river. In less than 150 years a market place, a castle and own units developed. In the year 1412 the municipal law was lent to the small market town. 500 years ago silver was found close of the town. The discovery site was thereupon renamed as Silver Hill. The mine was however quickly exhausted. Industry Its principal industries are the manufacture of glass, machinery, furniture and paper, and it produces a light lager " Radeberger Beer" which is largely exported. The company ''Robotron Elektronik Radeberg'', formerly well known in East Germany for the production of portable television sets and powerful ...

Xanthonoid
A xanthonoid is a chemical natural phenolic compound formed from the xanthone backbone. Many members of the Clusiaceae contain xanthonoids. Xanthonoid biosynthesis in cell cultures of ''Hypericum androsaemum'' involves the presence of a benzophenone synthase condensing a molecule of benzoyl-CoA with three malonyl-CoA yielding to 2,4,6-trihydroxybenzophenone. This intermediate is subsequently converted by a benzophenone 3′-hydroxylase, a cytochrome P450 monooxygenase, leading to the formation of 2,3′,4,6-tetrahydroxybenzophenone. Some examples are tomentonone, zeyloxanthonone and calozeyloxanthone isolated from the bark of ''Calophyllum tomentosum'', apetalinone A, B, C and D from '' Calophyllum apetalum'', gaudichaudione A, B, C, D, E, F, G, H, gaudichaudiic acid A, B, C, D, E, morellic acid and forbesione from '' Garcinia gaudichaudii'', methylswertianin and bellidifolin from '' Swertia punicea'' or psorospermin obtained from '' Psorospermum febrifu ...

1930 Births
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 '' Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from eleven states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The FRG's provisional capital was the city of Bonn, and the Cold War era country is retrospectively designated as the Bonn Republic. At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meissen
Meissen (in German orthography: ''Meißen'', ) is a town of approximately 30,000 about northwest of Dresden on both banks of the Elbe river in the Free State of Saxony, in eastern Germany. Meissen is the home of Meissen porcelain, the Albrechtsburg castle, the Gothic Meissen Cathedral and the Meissen Frauenkirche. The ''Große Kreisstadt'' is the capital of the Meissen district.

Sclerococcum
''Sclerococcum'' is a genus of lichenicolous fungi in the family Dactylosporaceae. Taxonomy The genus was circumscribed in 1825 by Elias Magnus Fries. The type species is '' Sclerococcum sphaerale'', originally described in 1814 by Erik Acharius (as ''Spiloma sphaerale''). This fungus is a lichenicolous hyphomycete – a mould that lives on a lichen. Most of the ''Sclerococcum'' species described since then are also lichenicolous, and most have a restricted host range. Molecular phylogenetic analysis published in 2012 showed that ''Sclerococcum sphaerale'' grouped together in a clade with species of ''Dactylospora'' in the class Eurotiomycetes. In 2016, Réblová and colleagues proposed a new family Sclerococcaceae in a new order (Sclerococcales) to accommodate the type genus ''Sclerococcum'', ''Dactylospora'', '' Rhopalophora'', three strains of beetle-associated fungi, and an isolate of '' Fusichalara minuta''. This classification was not accepted in the 2017 ''Outline of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lecidella
''Lecidella'' is a genus of crustose lichens in the family Lecanoraceae. Taxonomy ''Lecidella'' was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855. It was not widely used until more than a century later, when Hannes Hertel recognized it first as a subgenus of ''Lecidea'', and then a couple of year after as a distinct genus. A phylogenetic analysis of the genus using 11 species (mostly from China) found that ''Lecidella'' species fall into three major clades, which were proposed as three informal groups: ''Lecidella stigmatea'' group, ''L. elaeochroma'' group and'' L. enteroleucella'' group. Description ''Lecidella'' species have a thallus that is crustose, and biatorine, meaning that it resembles the genus '' Biatora''–having a proper exciple, which is not coal-black, but coloured or blackening. It has eight-spored asci of the ''Lecidella'' type. The ascospores are simple and hyaline, while the conidia are curved and threadlike. Morphologically simi ...

Lendemer , Mycologia 103(6): 1216-1229/ref> Members of the genus are List of lichen common names and their genera, commonly called dust lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The main vegetative body (thallus) is made of patches of soredia (little balls of algae wrapped in fungus). There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products (i.e., secondary metabolites made by lichens) are important character ...

International Association For Lichenology
The International Association for Lichenology (IAL) is an organisation that encourages the understanding of lichens and lichenology, and promotes their study and conservation worldwide. It unites lichenologists across the globe, as well as national and regional organisations into one group. It is affiliated to the International Union of Biological Sciences (IUBS). The IAL organises field courses and excursions, as well as symposia which are the biggest events in lichenology on the international level. The 8th International Symposium will be held in Helsinki, Finland, in August 2016. The IAL publishes a biennial journal, the International Lichenological Newsletter which was the raison d'etre for the IAL being formed in 1967 in order to provide a forum for lichenologists worldwide to communicate with one other. Nowadays the IAL also operates an online discussion forum for lichenologists known as 'lichens-L'. History The International Lichenological Association arose out of the 10th I ...
