Chloroplasts or cells from maize (Zea mays) bundle sheath show a very low intensity of delayed light emission compared with mesophyll protoplasts or chloroplasts. The bundle-sheath chloroplasts retain only the fast (less than 1 ms) component of the emission. They also fail to show fluorescence induction in contrast to the mesophyll, which behaved normally. The mesophyll material could be made to resemble the bundle-sheath chloroplasts in respect of both phenomena by adding to it 1-(3′,4′-dichlorophenyl)-3,3-dimethyl-urea and hydroxylamine, together. It is concluded that Photosystem II, that gives rise to both effects, is not active in the bundle sheath but may be present in an inhibited form.

Sheath Cells

Mesophyll and bundle-sheath cells from maize (Zea mays) were examined for delayed light-emission. An enzymic procedure was used to isolate the mesophyll and bundle-sheath cells. A tunable dye laser was used at 695-720 nm to excite delayed light-emission. The mesophyll cells show a typical Photosystem-II dependence on excitation wavelength for delayed light-emission, and this emission was eliminated by hydroxylamine and 3-(3,4-dichlorophenyl)-1,1-dimethylurea. The bundle-sheath cells show no delayed light-emission with these excitation wavelengths. Photosystem-I emission was not observed from either cell type, there being no effect of Methyl Viologen on the observed signals.
