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]
The monetary value of the lost corn crop was estimated at one billion US dollars at the time. [1] This would be more than six billion US dollars by 2015 standards. In 1971 SCLB losses had basically disappeared. This was due to the return usage of normal cytoplasm corn, not as conducive weather, residues being buried, and planting early. [10]
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 ...
Taxonomic databases digitize scientific biodiversity data and provide access to taxonomic data for research. [1] Taxonomic databases vary in breadth of the groups of taxa and geographical space they seek to include, for example: beetles in a defined region, mammals globally, or all described taxa in the tree of life.

Evolution of angiosperms shown in diagram format, per APG IV. The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG).
Bipolaris sacchari is a fungal plant pathogen in the family Pleosporaceae. Bipolaris sacchari is an ascomycete fungal pathogen most notably affecting sugarcane. In its sexual stage, it produces spores housed in an ascus (a sac, usually with 8 spores inside).
A simple cladogram showing the evolutionary relationships between four species: A, B, C, and D. Here, Species A is the outgroup, and Species B, C, and D form the ingroup. In cladistics or phylogenetics, an outgroup [1] is a more distantly related group of organisms that serves as a reference group when determining the evolutionary relationships of the ingroup, the set of organisms under study ...
