Arabidopsis	At3g50310	Mitogen-activated protein kinase kinase (MAPKK) that phosphorylates both MKK3 and MPK18 and regulate two separate signaling pathways involved in root microtubule functions.	Arabidopsis MKKK20 is involved in osmotic stress response via regulation of MPK6 activity.; 2012; DOI: 10.1007/s00299-011-1157-0; PMID: 21969089; https://pubmed.ncbi.nlm.nih.gov/21969089/ | AIK1, A Mitogen-Activated Protein Kinase, Modulates Abscisic Acid Responses through the MKK5-MPK6 Kinase Cascade.; 2017; DOI: 10.1104/pp.16.01386; PMID: 27913741; https://pubmed.ncbi.nlm.nih.gov/27913741/ | The  Arabidopsis  Mitogen-Activated Protein Kinase Kinase Kinase 20 (MKKK20) Acts Upstream of MKK3 and MPK18 in Two Separate Signaling Pathways Involved in Root Microtubule Functions.; 2017; DOI: 10.3389/fpls.2017.01352; PMID: 28848569; https://pubmed.ncbi.nlm.nih.gov/28848569/
Arabidopsis	At5g66850	Mitogen-activated protein kinase (MAPK) involved in the transduction of signal between the host cell surface chitin receptor complex CERK1-LYK5 and the intracellular MAPK cascade that leads to chitin-induced immunity.	The Arabidopsis CERK1-associated kinase PBL27 connects chitin perception to MAPK activation.; 2016; DOI: 10.15252/embj.201694248; PMID: 27679653; https://pubmed.ncbi.nlm.nih.gov/27679653/
