“…LYK-I is the largest orthogroup, containing the functional legume LCO receptors MtLYK3/LjNFR1 and LjNFRe (Limpens et al, 2003;Radutoiu et al, 2003;Murakami et al, 2018). Besides these, the LYK-I orthogroup also includes chitin innate immune receptors of M. truncatula MtLYK9/MtCERK1, L. japonicus LjCERK6, Arabidopsis (Arabidopsis thaliana) AtCERK1, tomato (Solanum lycopersicum) SlLYK1, and rice OsCERK1 (Limpens et al, 2003;Miya et al, 2007;Wan et al, 2008;Shimizu et al, 2010;Miyata et al, 2014;Zhang et al, 2015;Bozsoki et al, 2017;Carotenuto et al, 2017;Liao et al, 2018;Gibelin-Viala et al, 2019;He et al, 2019). OsCERK1 and MtLYK9/MtCERK1 have also been found to function in AM symbiosis (Miyata et al, 2014;Zhang et al, 2015;Feng et al, 2019;Gibelin-Viala et al, 2019).…”
