Ulvans are water-soluble sulfated heteropolysaccharides extracted from the cell walls of
green marine macroalgae Ulva spp. and are able to induce systemic resistance in plants. The aim of
this report is to summarize the main results of our research group, from discovery to attempts in
elucidating the mechanisms of action. A bioprospecting study carried out between 2002 and 2004
identified Ulva fasciata Delile as a potential source of active compounds for controlling plant
diseases. In greenhouse, spray of Ulva extracts reduced (about 80%) the number of powdery mildew
colonies on pre-treated leaves. When applied under field conditions, sprays of the algal extracts were
also able to control anthracnose by 50% in a highly susceptible bean cultivar. Follow-up studies
revealed that ulvans were the main elicitor molecules in the extracts of Ulva. In greenhouse, ulvans
demonstrated to protect several crop plants such as beans, apple, grapevine and cereals (e.g. wheat
and barley) against a broad range of foliar phytopathogens, including biotrophic, hemibiotrophic and
necrotrophic fungi. Pretreatment of barley leaves with ulvans significantly reduced the severity of
Blumeria graminis by 80%, and in cereals, priming effect was detected in assays with suspensioncultured
cells. Resistance induced by ulvans reduced the bean anthracnose severity by 50%, lasting at
least up to nine days after treatment. Protection levels of 65% were recorded in ulvans-treated apple
plants against the Glomerella leaf spot, but the effect was weaker in not-directly treated distal parts.
Jasmonic acid pathway as well the enzyme NADPH oxidase were triggered during ulvan-induced
resistance in Arabidopsis thaliana. These findings may open new horizons for using the algal
polysaccharides as resistance inducers. MenosUlvans are water-soluble sulfated heteropolysaccharides extracted from the cell walls of
