Cochliobolus miyabeanus is an important plant pathogen because it causes a common and widespread rice disease that causes high level of crop yield losses. It was a major cause of the Bengal famine of 1943, where the crop yield was dropped by 40% to 90% and the death of 2 million people was recorded. [3]
Southern corn leaf blight (SCLB) is a fungal disease of maize caused by the plant pathogen Bipolaris maydis (also known as Cochliobolus heterostrophus in its teleomorph state). The fungus is an Ascomycete and can use conidia or ascospores to infect. [ 1 ]
Oryza is a genus of plants in the grass family. [3] [4] It includes the major food crop rice (species Oryza sativa and Oryza glaberrima).Members of the genus grow as tall, wetland grasses, growing to 1–2 metres (3–7 ft) tall; the genus includes both annual and perennial species.
The taxonomy of Cochliobolus, Bipolaris and Curvularia is confusing due to the frequent name changes and no clear morphological demarcation between Bipolaris and Curvularia. A phylogenetic analysis of Cochliobolus, Bipolaris and Curvularia species was performed using rDNA markers (ITS1, 5.8S, ITS2) and a 600 bp fragment of gpd (glyceraldehyde-3 ...
The fungus Cochliobolus sativus is the teleomorph (sexual stage) of Bipolaris sorokiniana (anamorph) which is the causal agent of a wide variety of cereal diseases. The pathogen can infect and cause disease on roots (where it is known as common root rot), leaf and stem, and head tissue.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
The Roman numerals used correspond to the last digit of today's naming convention (e.g. the group 4 elements were group IVB, and the group 14 elements were group IVA). In Europe, the lettering was similar, except that "A" was used for groups 1 through 7, and "B" was used for groups 11 through 17. In addition, groups 8, 9 and 10 used to be ...
