The changes of calcium concentration of the P. heterophylla root tip after the infection by F.oxysporum. a The control without adding the fungal suspension, but sprayed with sterile water (CK), b the treatment infected by F.oxysporum but without spraying the blocker (F.OX), c the root tip infected by F.oxysporum and sprayed with 20 mM Trifluoroperazine Dihydrochloride (F.OX + 20 mM TFP), d the root tip infected by F.oxysporum and sprayed with 20 mM Verapamil (F.OX + 20 mM Verapamil), e the root tip infected by F.oxysporum and sprayed with 20 mM Lanthanum (III) chloride-anhydrous (F.OX + 20 mM LaCl3), f the root tip infected by F.oxysporum and sprayed with 2% HS (F.OX + 2% HS). All of the figures were taken under ten times fluorescence microscope with the white 100 μm ruler line. The deeper the intensity of the fluorescence suggests the higher concentration of the calcium ion in the root tips
