Fig. 4. Effect of narnaviruses in the asexual and sexual reproduction of R. microsporus.

a Sporangiospores produced by 814 wt and its variants on half-strength PDA at 30 °C, after 6 days of culture. b Zygospores produced by the mating of strain 813 wt and 814 wt and its variants on MEA medium at 30 °C. Each symbol represents spores quantified from a single agar plate. Bars indicate the arithmetical mean. Different letters denote statistical differences between strains by one-way ANOVA followed by Tukey’s post-hoc test, P < 0.05, n = 4–6, for each strain as described in Table 1. * most strains nv−b− did not produce zygospores.
