Lolium multiflorum Lam. ssp. italicum (A. Br.) Volkart
Bacterial wilt of Italian ryegrass, caused by Xanthomonas translucens pv. graminis, affects the vascular system of the plant. The disease leads to the disruption of water and nutrient transport due to the clogging of vessels by bacterial mass.
In the reference 13 varieties crop Italian ryegrass, where this is mentioned in the description.
The pathogen, Xanthomonas translucens pv. graminis, enters the tissues of Italian ryegrass primarily through mechanical injuries, although it is capable of infecting the plant without them. Bacteria actively colonize the tissues, concentrating in the stomatal region and causing systemic wilting.
In the genome of Italian ryegrass, a quantitative trait locus (QTL) responsible for resistance to this pathogen has been identified and localized on linkage group 4. In this region, genes encoding Pik2-like proteins have been identified, which are key factors in breeding for resistance to bacterial wilt.
