Arabidopsis	At1g62760	Pectin methylesterase (PME) inhibitor involved in the maintenance of cell wall integrity in response to necrotrophic pathogens.	No verified direct reference in this release
Arabidopsis	At1g62770	Pectin methylesterase (PME) inhibitor that probably targets root-expressed PME and PME3 in a moderate pH-dependent manner, mainly in slightly acidic conditions (pH 6.3 and 5.0) and to some extent at pH 7.5.	Combined Experimental and Computational Approaches Reveal Distinct pH Dependence of Pectin Methylesterase Inhibitors.; 2017; DOI: 10.1104/pp.16.01790; PMID: 28034952; https://pubmed.ncbi.nlm.nih.gov/28034952/
Arabidopsis	At4g25250	Pectin methylesterase (PME) inhibitor that can target the root-expressed PME17 and PME3 in a pH-dependent manner, mainly in slightly acidic conditions (pH 6.3 and 5.0) but not at pH 7.5; this processus relies on changes in the protonation of amino acids involved in intermolecular and intramolecular interactions.	Arabidopsis PME17 Activity can be Controlled by Pectin Methylesterase Inhibitor4.; 2015; DOI: 10.4161/15592324.2014.983351; PMID: 25826258; https://pubmed.ncbi.nlm.nih.gov/25826258/ | Combined Experimental and Computational Approaches Reveal Distinct pH Dependence of Pectin Methylesterase Inhibitors.; 2017; DOI: 10.1104/pp.16.01790; PMID: 28034952; https://pubmed.ncbi.nlm.nih.gov/28034952/
Arabidopsis	At2g47670	Pectin methylesterase (PME) inhibitor that targets PME from seeds and modulates PME activity and pectin methylesterification during seed germination.	PECTIN METHYLESTERASE INHIBITOR6 promotes Arabidopsis mucilage release by limiting methylesterification of homogalacturonan in seed coat epidermal cells.; 2013; DOI: 10.1105/tpc.112.106575; PMID: 23362209; https://pubmed.ncbi.nlm.nih.gov/23362209/
