Mathieu Tillet
Mathieu Tillet (10 November 1714 Bordeaux - 13 December 1791) was a French botanist, agronomist, metallurgist and administrator. Life He was the son of the goldsmith Gabriel Tillet and began studying metals at his father's workshop. In 1740 he was appointed Director of the Mint at Troyes. Ten years later he published his first book, about alloys. In 1750, he was awarded a prize by the Academy of Bordeaux for his research concerning the plagues of cereals, especially wheat. In 1755, he published the results of his research as ''Dissertation sur la cause qui corrompt et noircit les grains de blé dans les épis; et sur les moyens de prévenir ces accidents'' (''Explanation of the cause that corrupts and blackens the grains of wheat in the ears; and the means to prevent these accidents''), and was awarded another prize for it. The fungus '' Tilletia tritici'', which he describes in this work, was named after him a century later by Charles and Louis Tulasne. In 1756 he resigned from ...

Bordeaux
Bordeaux ( , ; Gascon oc, Bordèu ; eu, Bordele; it, Bordò; es, Burdeos) is a port city on the river Garonne in the Gironde department, Southwestern France. It is the capital of the Nouvelle-Aquitaine region, as well as the prefecture of the Gironde department. Its inhabitants are called ''"Bordelais"'' (masculine) or ''"Bordelaises"'' (feminine).

Pitié-Salpêtrière Hospital
Pitié-Salpêtrière University Hospital (french: Hôpital universitaire la Pitié-Salpêtrière, ) is a teaching hospital in the 13th arrondissement of Paris. Part of the and a teaching hospital of Sorbonne University. History The Salpêtrière was originally a gunpowder factory (saltpetre being a constituent of gunpowder), but in 1656 at the direction of Louis XIV, it was converted into a ''hospice'' for the poor women of Paris as part of the General Hospital of Paris. This main hospice was for women who were learning disabled, mentally ill or epileptic, as well as poor. In 1657 it was incorporated with the hospice of the Pitié designed specifically for beggars' children and orphans. Sheets for hospice and military clothing were produced there by the children. Between 1663 and 1673, 240 of the women at the Pitié-Salpêtrière hospice were sent on a mission to populate the Americas and help build New France. They were in the total number of 768 young women recruited during th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Lernet-Holenia
Alexander Lernet-Holenia (21 October 1897, in Vienna — 3 July 1976) was an Austrian poet, novelist, dramaturgist and writer of screenplays and historical studies who produced a heterogeneous literary opus that included poetry, psychological novels describing the intrusion of otherworldly or unreal experiences into reality, and recreational films. Youth and service in World War I Lernet-Holenia was born in 1897, as Alexander Marie Norbert Lernet to Alexander Lernet (an ocean liner officer) who had married his mother Sidonie (née Holenia) shortly before his birth. He attached his mother's maiden name to his family name only when he was formally adopted by Carinthian relatives of his mother (whose aristocratic family had lost most of its wealth after the war) in 1920. In July 1915, Alexander finished high-school in Waidhofen an der Ybbs and took up Law studies at the University of Vienna, but volunteered for the Austro-Hungarian army in September 1915 and fought in World War I ...

Tilletiaceae
The Tilletiales are an order of smut fungi in the class Exobasidiomycetes. It is a monotypic order, consisting of a single family, the Tilletiaceae, which contains seven genera. The roughly 150 species in the Tilletiales all infect hosts of the grass family, except for species of '' Erratomyces'', which occur on legumes A legume () is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. When used as a dry grain, the seed is also called a pulse. Legumes are grown agriculturally, primarily for human consumption, for livestock fo ....

Smut Fungi
The smuts are multicellular fungi characterized by their large numbers of teliospores. The smuts get their name from a Germanic word for dirt because of their dark, thick-walled, and dust-like teliospores. They are mostly Ustilaginomycetes (phylum Basidiomycota) and can cause plant disease. The smuts are grouped with the other basidiomycetes because of their commonalities concerning sexual reproduction. Smuts are cereal and crop pathogens that most notably affect members of the grass family (Poaceae) and sedges (Cyperaceae). Economically important hosts include maize, barley, wheat, oats, sugarcane, and forage grasses. They eventually hijack the plants' reproductive systems, forming galls which darken and burst, releasing fungal teliospores which infect other plants nearby. Before infection can occur, the smuts need to undergo a successful mating to form dikaryotic hyphae (two haploid cells fuse to form a dikaryon). Wild rice smut ''Ustilago esculenta'' is a species of fungus i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Tilletia
''Tilletia'' is a genus of smut fungi in the Tilletiaceae family. Species in this genus are plant pathogens that affect various grasses. '' Tilletia indica'', which causes Karnal bunt of wheat, and '' Tilletia horrida'', responsible for rice kernel smut, are examples of species that affect economically important crops. The widespread genus contains about 175 species. The genus was circumscribed by Edmond Tulasne and Charles Tulasne in Ann. Sci. Nat. Bot. ser.3, vol.7 on page 112 in 1847. The genus was named after a agronomist from France, Mathieu Tillet (1714–1791).

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Edmond Tulasne
Louis René Étienne Tulasne, a.k.a. Edmond Tulasne (12 September 1815 – 22 December 1885) was a French botanist and mycologist born in Azay-le-Rideau. He originally studied law at Poitiers, but his interest later turned to botany. As a young man he assisted botanist Auguste de Saint-Hilaire (1779–1853) with studies of Brazilian flora. From 1842 until 1872 he worked as a naturalist at the Muséum national d'histoire naturelle in Paris. In 1854 he succeeded Adrien-Henri de Jussieu (1797–1853) as a member of the Académie des sciences. He died in Hyères on 22 December 1885, age 70. Tulasne's specialized study was the science of mycology. His microscopic investigation of fungi, particularly parasitic species, contributed much to the understanding on the complexities of their nature and development. He is credited with introducing the concept of " pleomorphy" in regard to fungi. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antoine Lavoisier
Antoine-Laurent de Lavoisier ( , ; ; 26 August 17438 May 1794), When reduced without charcoal, it gave off an air which supported respiration and combustion in an enhanced way. He concluded that this was just a pure form of common air and that it was the air itself "undivided, without alteration, without decomposition" which combined with metals on calcination. After returning from Paris, Priestley took up once again his investigation of the air from mercury calx. His results now showed that this air was not just an especially pure form of common air but was "five or six times better than common air, for the purpose of respiration, inflammation, and ... every other use of common air". He called the air dephlogisticated air, as he thought it was common air deprived of its phlogiston. Since it was therefore in a state to absorb a much greater quantity of phlogiston given off by burning bodies and respiring animals, the greatly enhanced combustion of substances and the greater e ...
