Figure 5. Histological observation of Pst growth using calcofluor staining.
All wheat leaves were inoculated with Pst strain CYR31; fluorescence-microscopic analyses were done 2 days post inoculation. A: BSMV:γ:0-as (empty viral vector control); B: BSMV:γ:PsCNA1-as (silencing for PsCNA1); C: BSMV:γ:PsCNB1-as (silencing for PsCNB1); IH: infection hyphae; HM: haustorial mother cell; SV: substomatal vesicle. Scale bars: 50 µm.
