Effect of the AM Fungus Sieverdingia tortuosa on Common Vetch Responses to an Anthracnose Pathogen.

ABSTRACT: Colletotrichum lentis Damm causes anthracnose in Vicia sativa L, otherwise known as common vetch. It was first reported in China in 2019. This study evaluates the effects of the arbuscular mycorrhizal (AM) fungus Sieverdingia tortuosa (N.C. Schenck & G.S. Sm.) Błaszk., Niezgoda, & B.T. Goto on growth and disease severity in common vetch. Our main finding is that the AM fungus increased root biomass and reduced anthracnose severity of common vetch. Responses correlated with defense, such as chitinase activity, polyphenol oxidase (PPO) activity, the concentrations of jasmonic acid and proline, and the expression of resistance-related genes (e.g., upregulated "signal transduction," "MAPK signaling pathway," "chitinase activity," "response to stress," and the KEGG pathways
