Geranium
''Geranium'' is a genus of 422 species of annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, but mostly in the eastern part of the Mediterranean region. The palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white, pink, purple or blue, often with distinctive veining. Geraniums will grow in any soil as long as it is not waterlogged. Propagation is by semiripe cuttings in summer, by seed, or by division in autumn or spring. Geraniums are eaten by the larvae of some Lepidoptera species including brown-tail, ghost moth, and mouse moth. At least several species of ''Geranium'' are gynodioecious. The species ''Geranium viscosissimum'' (sticky geranium) is considered to be protocarnivorous. Name The genus name is derived from the Greek (''géranos'') or (''geranós'') ' crane'. The English name ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glomerella Cingulata
''Glomerella cingulata'' is a fungal plant pathogen, being the name of the sexual stage (teleomorph) while the more commonly referred to asexual stage ( anamorph) is called ''Colletotrichum gloeosporioides''. For most of this article the pathogen will be referred to as ''C. gloeosporioides.'' This pathogen is a significant problem worldwide, causing anthracnose and fruit rotting diseases on hundreds of economically important hosts. Hosts and symptoms ''C. gloeosporioides'' has an extremely broad host range, causing anthracnose disease on a variety of crops such as cereals and grasses, legumes, fruits, vegetables, perennial crops, and trees. It has been observed as infecting harvested durian of the species ''Durio graveolens''. Some studies suggest that ''C. gloeosporioides'' has sub-populations specific to each host.Nelson, C.

Discohainesia Oenotherae
''Discohainesia'' is a genus of fungi in the family Dermateaceae.

Ascochyta
''Ascochyta'' is a genus of ascomycete fungi, containing several species that are pathogenic to plants, particularly cereal crops. The taxonomy of this genus is still incomplete. The genus was first described in 1830 by Marie-Anne Libert, who regarded the spores as minute asci and the cell contents as spherical spores. Numerous revisions to the members of the genus and its description were made for the next several years. Species that are plant pathogenic on cereals include, '' A. hordei'', '' A. graminea'', '' A. sorghi'', '' A. tritici''. Symptoms are usually elliptical spots that are initially chlorotic and later become a necrotic brown. Management includes fungicide applications and sanitation of diseased plant tissue debris. Some of these pathogens in the genus ''Ascochyta'' affect grass species, including grains. Some species of ''Ascochyta'' *'' Ascochyta asparagina'', Ascochyta blight *'' Ascochyta bohemica'' *'' Ascochyta boltshauseri'' *'' Ascochyta caricae'', S ...

Cochliobolus Heterostrophus
''Cochliobolus heterostrophus'' is a fungal plant pathogen. It can cause southern corn leaf blight in maize. ''Cochliobolus heterostrophus'' is found in many tropical regions and in the southern part of the US. ''Cochliobolus'', although not currently the most economically serious disease, can be a very serious crop disease. ''C. heterostrophus'' (race O) was considered a mild pathogen of corn, and was of little worry to those growing maize crops. It was not until the 1970s that ''C. heterostrophus'' (race T) destroyed more than 15% of the U.S. corn crop. Race T differed from race O in the sense that it produced T-toxin (host-selective toxin). The corn planted in the 1970s carried T-cms; T-cms was particularly susceptible to T-toxin. T-toxin is considered to be related to a family of linear polyketide Polyketides are a class of natural products derived from a precursor molecule consisting of a chain of alternating ketone (or reduced forms of a ketone) and methylene grou ...

Alternaria Tenuis
''Alternaria alternata'' is a fungus which has been recorded causing leaf spot and other diseases on over 380 host species of plant. It is an opportunistic pathogen on numerous hosts causing leaf spots, rots and blights on many plant parts. It can also cause upper respiratory tract infections and asthma in humans with compromised immunity. Hosts and symptoms ''Alternaria alternata'' has many different hosts depending on its forma specialis. In this review, only ''Alternaria alternata'' f. sp. ''lycopersici'' (AAL) is going to be assessed. This pathogen infects only certain cultivars of tomato plants and is often referred to as Alternaria stem canker of tomato. AAL's main symptom is cankers in the stem. It resides in seeds and seedlings, and is often spread by spores as they become airborne and land on plants. It can also spread throughout other plants. Under severe infection, lesions enlarge and become coalesced causing blighting of the leaves. This symptom progression occur ...
