Current understanding of the Diaporthe/Phomopsis complex causing soybean stem canker:A focus on molecular aspects of the interaction.

Soybean stem canker (SSC) is an important disease caused by different Diaporthe spp., including D. aspalathi, D. caulivora and D. longicolla, that leads to soybean (Glycine max) yield losses around the world. Most studies have been focused on the morphological characterization and molecular identification of Diaporthe spp. present in SSC lesions. Several soybean resistance loci to Diaporthe spp. causing SSC have been identified, although the molecular identities of the resistance genes are at present unknown.
