Rice-sheath blight is a disease caused by Rhizoctonia solani (teleomorph is Thanetophorus cucumeris), a basidiomycete, that causes major limitations on rice production in India and other countries of Asia. [1] It is also a problem in the southern US, where rice is also produced. [2] It can decrease yield up to 50%, and reduce its quality. [3]
oryzae and rice at many levels, including studies focused on the epidemiology, population biology, physiology, cell biology, biochemistry, and molecular genetics of the host pathogen interaction. It is very notable that BB became the first case where the genome sequencing of both host plant and pathogen was completed.

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]
Three rice producers in the Valencia region said their harvest of arroz bomba, or bomb rice, a variety grown almost exclusively in Spain, was half the 10-year average in 2023 as a result of the ...
