Summary
Plant heterokaryons were identified and isolated from a population of protoplasts following fusion. Endogenous chlorophyll autofluorescence and exogenously supplied fluorochromes were utilized to differentiate between parental and heterokaryon populations. Flow cytometric analysis detected heterokaryons based upon the simultaneous presence of both chlorophyll and an exogenously supplied fluorochrome within one cell. These parameters were utilized to sort large numbers of heterokaryons from the fusion mixture using modified flow instrumentation. Modifications to the instrumentation which allowed this sorting are discussed.
