Isolation and identification of a phytoalexin from sugarcane

Literature reports concerning the sugarcane disease, red rot (causal agent Colletotrichum falcatum Went; teleomorph Glomerella tucumanensis (Speg.) von Arx and E. Muller), indicate that disease resistance is associated with production of a red material. This red substance accumulates in sugarcane (Saccharum spp.) cells infected by or adjacent to hyphae of C. falcatum, and appears to inhibit further hyphal growth. Resistant sugarcane cultivars reportedly produce the red material more quickly after infection than susceptible cultivars. Previous workers had identified luteolinidin, an anthocyanidin, in extracts of infected sugarcane and suggested that the compound was a phytoalexin. However, the role of this compound was not unambiguously established. This study was undertaken to determine whether sugarcane produces phytoalexins of other chemical classes.
