TABLE 4.

Duncan’s multiple range test for difference in UVC tolerance among RAD4 isoforms measured by the mycelia growth rate of Phytophthora infestans isolates treated with UVC relative to no UV treatment (RGR).

Isoform	N *	Mean RGR
Iso_1	2,587	0.94 ± 0.11 A**
Iso_2	210	0.91 ± 0.12 B
Iso_3	42	0.89 ± 0.07 B

*Number of data points included in the analysis. The data points were generated from 140 isolates in seven UVC treatments each with three replicates.

**Value in a column followed by different letters indicates statistical difference at p = 0.05.
