To further determine the tissue localisation of the Ab-FAR-1 protein and the secretion process after nematode infection, we performed immunofluorescence localisation analysis of Ab-FAR-1 without a signal peptide (Ab-FAR-1Δsp) on RWTN bodies and plant sections from A. thaliana infected with RWTNs at 3 dpi. Here, FAR1 is linked to Nematoda infectious disease.
