Citrus bacterial canker (CBC) disease, caused by Xanthomonas citri subsp. ( Xcc ), is one of the major diseases that seriously endanger citrus production. regulates balance endogenous plant hormones to resist CBC through multiple synthetic pathways, including demethylation pathways methyl salicylate (MeSA), jasmonate (MeJA) and indole-3-acetic acid (MeIAA). Here, four methylesterase (MES) genes, MES1.1 , MES17.3 MES10.2 MES1.5 were screened in transcriptomes CBC-resistant CBC-susceptible varieties after inoculation. Among these MES expression levels up-regulated varieties, while was down-regulated both susceptible varieties. Subcellular localization analysis showed MES-encoding proteins localized cytoplasm. Overexpression CmMES1.1 CmMES1.5 from calamondin Citrofortunella microcarpa ) significantly enhanced resistance increased salicylic (SA) content calamondin. Conversely, overexpression CmMES10.2 CmMES17.3 reduced contents jasmonic (JA) (IAA), respectively. We concluded resistant confer CBC-resistance regulating increase SA content, inhibit synthesis JA IAA, Their ability regulate SA, IAA pathway an attractive breeding target for conferring resistance.
