AIG1 and Nematoda infectious disease: Plant homologs of the mammalian GiMAPs are known [37], and several of these have been implicated in immunity; in Arabidopsis, AIG1 (AtIAN8) is induced by both the plant pathogenic bacterium Pseudomonas syringae[48] and the fungal pathogen Phytophthora infestans[41], and atIAN3 and atIAN11 are strongly up-regulated on nematode infection [41].
