Defects of the Δ<i>amt1</i> mutant in growth, conidiation, and plant infection.

aAverage growth rate/conidiation and standard error (mean ± standard error) were calculated from at least three independent measurements. bDisease was rated by the number of symptomatic spikeletes 14 days after inoculation. Mean and standard error were calculated with results from three independent experiments. At least 10 wheat heads were examined in each repeat. *Data from three replicates were analyzed with the protected Fisher's Least Significant Difference (LSD) test. The same letter indicated that there was no significant difference. Different letters were used to mark statistically significant difference (P = 0.05).
