Table 2. Methylation levels per type of primer combination for each type of methylation status of the loci, the proportion of the banding is showed conditional to presence or absence of BF symptoms.

Type of primer combination	Methylation status of the loci	Proportion in BF accessions	Proportion in NBF accessions
HPA+/MSP+	Demethylated	0.439083	0.500477
HPA+/MSP−	Hemimethylated	0.085261	0.093192
HPA−/MSP+	Internal cytosine methylation	0.095542	0.111845
HPA−/MSP−	Full methylation	0.380113	0.294485
