Differences in fitness between heterokaryotic and homokaryotic derivatives of C98O622b. a Growth of four single-spore derivatives on the universally susceptible lettuce cv. Green Towers (GT). Heterokaryons exhibit higher growth mass per lettuce seedling and DNA quantity collected per ml of sporangia suspension. Area under the curve (AUC) measurements demonstrate significantly faster sporulation of heterokaryon derivative B compared with homokaryon derivative I (p < 0.01, n = 4). Error bars depict standard error over four replicates. b Growth curves of six heterokaryotic isolates (black lines) versus four homokaryotic isolates (red lines) on differential lettuce lines NunDM15 (Dm15) and R4T57D (Dm4) demonstrating that viable homokaryons sporulate faster on selective hosts than heterokaryons. Measurements were taken 7, 11, 15, and 21 days post inoculation (dpi) and sporulation was measure on 20 cotyledons per observation. Source data for all panels are provided in the Source Data file
