virus
China, Korea
Main: common bean, cowpea; Other: soybean
SBMV00
Southern bean mosaic virus infects beans and other legumes, producing mosaic leaf patterns, mottling, and reduced vigor. It is transmitted both by leaf beetles and through infected seed, particularly in beans and cowpea. Additional spread can occur mechanically from contact with sap or contaminated seed exudates. Several strains of Southern bean mosaic virus are known and are very specific to thier host. SBMV-B infects bean (Phaseolus vulgaris) but not cowpea (Vigna unguiculata), SBMV-CP infects cowpea, Ghana strain (SBMV-G) infects cowpeas and some bean cultivars, Mexican strain (SBMV-M) (Severe bean mosaic strain) infects beans and some cowpea cultivars.
3 Known Hosts
Glycine max
soybean
Yes
SBMV00-11, SBMV00-4, SBMV00-6, CABI CPC, DPV WEB, SBMV00-13
Soybean is not considered an important host of this virus. Produces a mild mottle when infected artificially. Seed as a pathway seems relatively unimportant and has primarily been shown with artificially inoculated plants from seed extracts.
Yes
ELISA
ELISA and other serological tests have been applied for other hosts. Test has not been validated or standardized.
