Mordecai Cubitt Cooke
Mordecai Cubitt Cooke (12 July 1825, in Horning, Norfolk – 12 November 1914, in Southsea, Hampshire) was an English botanist and mycologist who was, at various points, a London schoolteacher, a Kew mycologist, curator at the India Museum, journalist and author, .Mary P. English (1987), ''Mordecai Cubitt Cooke: Victorian naturalist, mycologist, teacher & eccentric''. Biopress, Bristol, ] Cooke was the elder brother of the art-education reformer Ebenezer Cooke (art education reformer), Ebenezer Cooke (1837–1913) and father of the book illustrator and watercolour painter William Cubitt Cooke (1866–1951). Life Cooke, from a mercantile family in Horning, Norfolk, was apprenticed to a fabric merchant before becoming a clerk in a law firm, but his chief interest was botany. He founded the ''Society of Amateur Botanists'' in 1862 while teaching natural history at Holy Trinity National School, Lambeth, and working as a curator at the India Museum at India Office from 1860. In 1879, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pier Andrea Saccardo
Pier Andrea Saccardo (23 April 1845 in Treviso, Treviso – 12 February 1920 in Padua) was an Italian botanist and mycologist. Life Saccardo studied at the Lyceum in Venice, and then at the Technical Institute of the University of Padua where, in 1867 he received his doctorate. He was an Assistant to Roberto de Visiani (1800-1878) an Italian botanist, naturalist and scholar. Then in 1869, he became a professor of Natural History in Padua. In 1876 he established the mycological journal ''Michelia'' which published many of his early mycological papers. In 1879 he became a professor of Botany and director of the botanical gardens of the university until 1915. He accumulated around 70,000 fungal specimens encompassing over 18,500 different species for his herbarium. Which is still stored at the university. Saccardo's scientific activity focused almost entirely on mycology. He wrote his first book in 1864 (when he was 19 years old), ''Flora Montellica: an introduction to ...

Sphaeria (fungus)
Sphaeria or Sphairia ( grc, Σφαιρία), later called Hiera (Ἱερά), is a former island of ancient Argolis described by Pausanias as in the immediate vicinity of Calaureia, and separated from the mainland (Peloponnesus) by a strait so narrow and shallow that there was a passage over it on foot. Pausanias wrote that on the island was the tomb of Sphaerus ( grc, Σφαίρος), who was a charioteer of Pelops. In addition, he wrote that according to legend Aethra saw Athena in a dream, and Athena told her to go to the island to give offerings to Sphaerus. Aethra went to the island and Poseidon had intercourse with her there. For this reason Aethra set up a temple of Athena Apaturia ( grc, Ἀθηνᾶς Ἀπατουρίας) on the island. Due to this the name of the island changed to Sacred (Ἱερά) Island. Furthermore, she also established a custom for the Troezenian maidens of dedicating their girdles before wedlock to Athena Apaturia. At present there is only one ...

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canker
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animals can spread canker, thereby endangering areas that have only slight amount of canker. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus '' Neonectria galligena'' * Ash bacterial canker, now understood to be caused by the bacterium ''Pseudomonas savastanoi'', rather than '' Pseudomonas syringae''. After DNA-relatedness studies ''Pseudomonas savastanoi'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemp
Hemp, or industrial hemp, is a botanical class of '' Cannabis sativa'' cultivars grown specifically for industrial or medicinal use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed. Although chemotype I cannabis and hemp (types II, III, IV, V) are both ''Cannabis sativa'' and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the psychoactive effects of THC. The legality of hemp varies widely among c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungal Plant Pathogens And Diseases
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
