Abstract/Contents: | "Dollar spot, caused by Sclerotinia homoeocarpa, is one of the primary diseases of turfgrass in the USA. However, little is known about the mechanisms involved in resistance of bentgrass to dollar spot. The objective of this work was to study non-host interactions between bentgrass and Colletotrichum graminicola, Colletotrichum orbiculare, or Sclerotinia sclerotiorum, and compare it to a compatible interaction where cultivar L-93 shows resistance to S. homoeocarpa isolate VCG-B. Leaf blades of L-93 were inoculated with the cited fungi. The number of penetration sites and deposition of lignin and callose were examined with the microscope 48 hours post inoculation. C. graminicola was restricted at the surface of the leaf blades, but C. orbiculare was able to penetrate into the epidermis. Lignification was observed in response to C. orbiculare. Bentgrass also showed lignification and necrosis after S. sclerotiorum penetration. Lignification was also observed when L-93 was infected with S. homoeocarpa, indicating that lignin deposition may be a common feature in both non-host and host resistance." |
