Efficacy of LGS1 loss-of-function varies across abiotic and biotic gradients. (A) Germination of two S. hermonthica populations in response to root exudate from 3-wk-old wild-type Macia and CRISPR–Cas9-edited sorghum seedlings with lgs1 deletion alleles. Plants were grown under well-watered high-nutrition (WWHN), well-watered low-nutrition (WWLN), or drought low-nutrition (DLN) conditions. Germination was 0% in response to diH₂O and 66% (Kibos) or 78% (Siby) in response to 0.2 μM GR24. (B) Origin of two tested S. hermonthica populations. (C) Germination of two S. hermonthica populations in response to synthetic SLs, (+)5-deoxystrigol (5-DS) or (±)orobanchol (ORO).
