Summary
An electron microscopic study of H2O- and D2O-cultured winterrye (Secale cereale L.cv. Winter) seedlings demonstrated that when compared to cells of H2O-cultured plants, cells of D2O-cultured plants contained many ribosomes (both in the cytoplasm and in the plastids), little smooth endoplasmic reticulum and dictyosomes with compressed cisternae and fewer cisternae per dictyosome. Chloroplasts from cells of D2O-cultured plants contained elongate grana with few lamellae per stack and electron dense partitions. Little stroma lamellae was present. However, numerous ribosomes were present in the stroma. Growth in D2O did not appear to affect microtubule morphology or occurrence.
