  1. The efficiency was quantified by determining the percentage of infected cells at 16 h post inoculation. For each sample a total of 500 cells was monitored in triplicate
  2. aCells that had been penetrated by Phytophthora were counted as infected
  3. bInfected cells due to primary infection i.e. penetrated by germ tubes emerging from cysts
  4. cInfected cells due to secondary infection i.e. penetrated by hyphae expanding from a neighbouring infected cell
  5. dInfected cells containing haustoria
  6. eAttachment of hyphae and scarce initial penetrations with no further growth of hyphae in the cell
