Rice stripe tenuivirus

[1] It is prevalent in Japan, China, and Korea and can infect plants of the family Poaceae, which include wheat and corn (see maize stripe virus).

[2] Damage from this disease causes major reductions in rice crop yield every year.

[2] It is spread primarily by Laodelphax[3] striatellus, a small planthopper that feeds and damages rice plants by sap-sucking.

[4] Three other planthopper insects that transmit rice stripe virus include Unkanodes sapporona, Unkanodoes albifascia, and Terthron albovittatum.

Infected mature plants do not have severe chlorosis or blotches, but ripening may be hindered.

Hybrid varieties Chugoku 31 and St No1 were bred in Japan by crossing japonica-type cv.
