Cerebroside C is a fungal metabolite and glycosphingolipid that has been found in the rice pathogenic fungus M. grisea.1 It induces production of the phytoalexin momilactone A when applied to wounded rice leaves, indicating that cerebroside C is an elicitor of the hypersensitive response in rice. Cerebroside C increases germination rate and reduces germination time in wheat seeds in a concentration-dependent manner at 4°C.2 It also increases root length, fresh weight, and dry weight of wheat seedlings when used at a concentration of 20 μg/ml at 4°C, indicating increased chilling tolerance.
