Trifolium pratense, red clover, is a herbaceous species of flowering plant in the bean family Fabaceae, native to Europe, Western Asia, and northwest Africa, but planted and naturalized in many other regions.
Clubroot is a common disease of cabbages, broccoli, cauliflower, Brussels sprouts, radishes, turnips, stocks, wallflowers and other plants of the family Brassicaceae (Cruciferae). It is caused by Plasmodiophora brassicae, which was once considered a slime mold but is now put in the group Phytomyxea. It is the first phytomyxean for which the genome has been sequenced. It has as many as thirteen races. Gall formation or distortion takes place on latent roots and gives the shape of a club or spindle. In the cabbage such attacks on the roots cause undeveloped heads or a failure to head at all, followed often by decline in vigor or by death. It is an important disease, affecting an estimated 10% of the total cultured area worldwide.
Tomato bushy stunt virus (TBSV) is a virus of the tombusvirus family. It was first reported in tomatoes in 1935 and primarily affects vegetable crops, though it is not generally considered an economically significant plant pathogen. Depending upon the host, TBSV causes stunting of growth, leaf mottling, and deformed or absent fruit. The virus is likely to be soil-borne in the natural setting, but can also be transmitted mechanically, for example through contaminated cutting tools. TBSV has been used as a model system in virology research on the life cycle of plant viruses, particularly in experimental infections of the model host plant Nicotiana benthamiana.
Pyrenopeziza brassicae is a plant pathogen infecting Brassicaceae.
Alternaria brassicae is a plant pathogen able to infect most Brassica species including important crops such as broccoli, cabbage and oil seed rape. It causes damping off if infection occurs in younger plants and less severe leaf spot symptoms on infections of older plants.
Stemphylium botryosum is a species of fungi and plant pathogen infecting several hosts including alfalfa, red clover, peanut, soybean, lentils, beet, tomato, lettuce, hemp and carnations.
Urocystis brassicae is a gall smut and a plant pathogen that stunts the infected plants. It is known to create root galls on Indian Mustard and other Brassica species.
Curvularia trifolii is a plant pathogen.
Tobacco necrosis virus A (TNV) is a plant pathogenic virus of the family Tombusviridae.
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected the stomach tissue of a mosquito.
Muriel Ross Abdurahman was a politician from Alberta, Canada. She served in the Legislative Assembly of Alberta from 1993 to 1997.
Clover Bar Bridge and Beverly Bridge are a pair of bridges that span the North Saskatchewan River in the city of Edmonton, Alberta, Canada. The twin spans carry 6 lanes total of Yellowhead Trail, the name given to Alberta Highway 16 within Edmonton city limits.
