*) Predicted molecular function is from TAIR (arabidopsis.org). LRR-RLKs were further classified into receptors and co-receptors according to [78]. @) Predicted localization is from SUBA (https://suba.live) [79]. §) Co-expression values R2 (Pearson′s correlation coefficient) were calculated from expression values obtained from TRAVA (http://travadb.org) [77] and kindly provided by Anna Klepikova (The Institute for Information Transmission Problems, Moscow, Russian Federation). For quick recognition R2 values ≥0.5 are in red, R2 values ≥0.1 and <0.5 are in green, and R2 values <0.1 are in blue. x) The indicated type of genetic interaction are my interpretations of published genetic experiments (double and higher order mutants): D: genetic action depends on FLA4-FEI, I: genetic action is independent from FLA4-FEI, +: synergistic action, −: antagonistic action, n.d.: (direction of) interaction has not been ascertained. 1) Due to their possible relevance for the pathway HPGT1, -2 and -3 as well as CESA1,-2,-3, -4, -7 -8 and -9 are also included in this list, although genetic interactions with FLA4-FEI core components have not been published.
