Fig. 6From: Cobalt oxide nanoparticles aggravate DNA damage and cell death in eggplant via mitochondrial swelling and NO signaling pathwayRepresentative flow cytometric images showing concentration dependent change in the mean fluorescence intensity (MnXI) of fluorescence probes DAF2-DA and CFDA specific for intracellular nitric oxide (NO) (a) and esterase activity (c) in eggplant protoplasts. Histograms shown in panel b and d represents changes in the mean ± SD of fluorescence of DAF2-DA and CFDA (MnXI) obtained from 10,000 protoplasts in three independent experiments (*p < 0.05, **p < 0.01 vs. control)Back to article page
