qRT-PCR analysis of P. tomentosa selective DEGs HP: healthy plantlets. PIP: phytoplasma-infected plantlets. PIP-60: phytoplasma infected plantlets with 60 mg · L⁻¹ MMS treatment. a: relative expression of lysine-specific histone demethylase 1 homolog 3 (LSD1); b: relative expression of spermidine synthase (SRM); c: relative expression of leucine carboxyl methyltransferase (Lcmt); d: relative expression of MET1-type DNA-methyltransferase (MET1); e: relative expression of histone h1/h5 (Histone h1/h5); f: relative expression of methionine aminopeptidase (MetAP); g: relative expression of adenosylhomocysteinase isoform 1 (Ahcyl); h: relative expression of histone acetyltransferase (HAT); i: relative expression of S-adenosyl-L-methionine -dependent methyltransferase domain-containing protein (AdoMet-dMT); i: relative expression of histone-lysine N-methyltransferase (HKMT); k: relative expression of arginine N-methyltransferase 3 (PRMT3); l: relative expression of cysteine desulfurase (IscS); m: relative expression of histone 2 (Histone 2); n: relative expression of histone deacetylase 14 (HDA14); o: relative expression of histone H3 (Histone h3); p: relative expression of lysine-specific demethylase LF6-like (LSD-LF6); The different letters within a gene repression level indicate significant difference, while the same letters within a gene repression level indicate no significant differences (p < 0.05), the same below
