発明の名称 (英語) SORGHUM PURPLE LEAF SPOT-RELATED GENE AND USE OF SAME
発明の概要(英語) As the results of a mapping of a purple leaf spot disease gene ds1 in populations F3 to F5 obtained by mating a purple leaf spot-resistant variety with a disease variety, the gene was successfully identified. Further, it was discovered that resistance to purple leaf spot can be imparted to sorghum by inhibiting the expression of the ds1 gene or mutating the same.
従来技術、競合技術の概要(英語) BACKGROUND ART
(Purple leaf spot) point disease is immune thrombocytopenic purpura, in spots is caused by a fungus diseases, diseases of the vehicle at Kanto generated in sub-Saharan warming. Japan cultivated sorghum (sorghum plant belonging to the genus) varieties, susceptibility to a disease that is 8 and the interrupt point purpura, in recent years, in its occurrence has been increasing. Disease in an individual infected with purpura point, generally red purple-brown leaf spots occur. Product class in a yellow-brown, orange, red-brown from red spot is caused in some cases. The spots spread, 0.3-1 cm width length 0.5-2 cm and the spindle shape of the lesions.
Sorghum is, heretofore, in a country Japan, feeding animals mainly cultivated but, in recent years, as a raw material for biofuel (ethanol) has become a focus of attention as also. For this reason purpura disease point to prevent the decline of the diseases is by sorghum, as well as agricultural policy, energy policy on top of a critical issue.
In sorghum up to now, was the main applications such as livestock feed, purpura point for controlling the disease, with little in the current situation is not taken.
On the other hand, between the type of sorghum, thrombocytopenic purpura is a difference between the point resistance to disease has been known. For this reason resistance breeding for the purpose of the species, this resistance for the elucidation of genetic manner attempts have been made. As a result, resistance to disease purpura point sorghum, governed in a single recessive gene has been determined (non-patent document 1) has been developed.
However, still, susceptibility to a disease purpura point sorghum gene responsible for resistance and has not been identified, and the position of the entity on its chromosome remains unclear.
