Description
Sara Rodriguez-Mena and co-authors report the first systematic test of how grass pea stands up to Aphanomyces euteiches. Grass pea is a hardy legume crop, and the water mold rots the roots of peas and lentils. The team inoculated 169 grass pea accessions from a worldwide collection with a single strain of the pathogen and scored leaf and root symptoms twenty days later.
Responses ranged widely, from fully susceptible plants to some with partial or even complete resistance. Scanning nearly thirteen thousand DNA markers across the collection tied resistance to twenty markers spread over five of the seven chromosomes, a pattern pointing to many genes each contributing a little. Seven nearby candidate genes touch on transport, signaling, cell wall building, and fat and hormone pathways. The authors offer the resistant lines and markers as starting material for breeding tougher grass pea varieties.
