These infection assays revealed significantly increased growth of Hpa Noco2 and Psm ES4326 in the fip37-4 mutant compared to wild-type (WT) plants, and this enhanced susceptibility was rescued in the gFIP37-GFP/fip37-4 transgenic complementation plants (5) (Fig. 1 A and B). This evidence concerns the gene HPSE and infection.
