Summary
Aggregations of approximately 11 nm spaced spherical particles are described in both freeze-fractured and chemically fixed bean and spinach leaf plastids. It is suggested that the aggregations were induced as a result of the dehydrating action of the cryoprotectants used. It is tentatively concluded, on the basis of previous reports, that the aggregations consist of Fraction I protein.
