Four <i>MES</i> genes from calamondin (<i>Citrofortunella microcarpa</i>) regulated citrus bacterial canker resistance through the plant hormone pathway.

ABSTRACT: Citrus bacterial canker (CBC) disease, caused by Xanthomonas citri subsp. citri (Xcc), is one of the major diseases that seriously endanger citrus production. Citrus regulates the balance of endogenous plant hormones to resist CBC through multiple synthetic pathways, including the demethylation pathways of methyl salicylate (MeSA), methyl jasmonate (MeJA) and methyl indole-3-acetic acid (MeIAA). Here, four methylesterase (MES) genes, MES1.1, MES17.3, MES10.2, and MES1.5 were screened in the transcriptomes of CBC-resistant and CBC-susceptible varieties after Xcc inoculation. Among these MES genes, the expression levels of MES10.2, MES1.1, and MES1.5 were up-regulated in CBC-resistant varieties, while MES1
