Strigolactone (SL) biosynthetic mutants have repeatedly been associated with reduced germination of parasitic Orobanchaceae in vitro. However, the extent to which this translates into field resistance has been poorly investigated. Based on replicated field trials, we show that although the SL-deficient pea mutants rms1 and rms5 are more resistant to Orobanche crenata (Oc) than their […]
