Effects of pharmacological compounds on nucleus-mitochondria and nucleus-plastid interactions. Rates of the nuclei interacting with mitochondria (A) or plastids (B) in the root epidermal cells were scored. The columns show averaged interaction-rates in the observed cells with standard deviations. Significantly different (P ≤ 0.01) rates from the mock treated samples are indicated with asterisks. Mock: 0.1% (v/v) dimethyl sulfoxide (N = 128), Lat: 40 μM latrunculin B (N = 88), Ory: 10 μM oryzalin (N = 86), DNP: 40 μM 2, 4-dinitrophenol (N = 34), BDM: 20 μM 2, 3-butanedione monoxime (N = 42), NEM: 50 μM N-ethylmaleimide (N = 84), NEM/Lat: 50 μM N-ethylmaleimide and 40 μM latrunculin (N = 61), NEM/Ory: 50 μM N-ethylmaleimide and 10 μM oryzalin (N = 62).
