	Producing anthocyanin	With tumors	Infected (total)
a1b1 × a2b2	12	87	99	88	3.7
a1b1 × Δmfe2 a2b2	16	95	106	90	3.4

Δmfe2 a1b1 × Δmfe2 a2b2	75	28	103	27	1.2

^aTable shows combined data from four independent experiments.

^bThe disease score is calculated as the sum of disease symptom ratings divided by the total number of infected plants scored for symptoms.
