Xanthomonas translucens (ex Jones, Johnson & Reddy 1917) Vauterin, Hoste, Kersters & Swings 1995 - (bacterial leaf streak of cereals)

This bacterium is widely distributed and causes wilt and leaf streak diseases. It infects a large variety of crops, in particular cereals and grasses. Yield losses are typically 10% or less, but on highly susceptible cultivars, severe infection can cause up to 40% yield losses. Various pathovars have been described, and these typically have a narrow host range.
