Clavibacter nebraskensis is a species of bacteria in the genus Clavibacter. It causes wilt and blight in maize, called Goss's wilt.

Range

Goss's wilt was first detected in the United States in 1969 in Nebraska and surrounding states. Between 2006 and 2017, the disease reemerged in the US and spread to Canada ranging from Colorado in the west to Indiana in the east. The southern range extended south from Texas and north to Canadian provinces Alberta and Manitoba. The disease was also found in Mexico in 2023 and South Africa in 2024.

Genetics

An annotated nucleotide sequence was expected to be available soon after 2011. The single chromosome is of 3.06 megabases (of which the GC-content is 73.0), mostly collinear, and contains 2 rRNA operons, and 45 tRNAs. As of 2011 when a partial annotation was available, it appeared to contain 50 pseudogenes and no insertion elements. A chloride channel is suspected to be a virulence factor.
