GTPase Activity of the Nucleoid Localizing NOA1 Correlates with NO Accumulation.
(A) Percentage nucleoids showing fluorescence in water-, glycerol-, or pathogen-treated plants. Nucleoids were purified from treated plants and assayed for fluorescence under a confocal microscope. The experiment was repeated twice with similar results.
(B) GTPase activity associated with nucleoids purified from water-, glycerol-, or pathogen-treated plants at 12 h after inoculation. Protein was extracted from 108 nucleoids, and E. coli–purified NOA1 protein was used as a positive control. The experiment was repeated twice with similar results.
