plastocyanin/zea mays

A comparison of plastocyanin isolated from pea and corn leaves was made according to a number of indices. No appreciable differences were detected between the proteins in molecular weight or sedimentation constants. In addition, it was shown that plastocyanin of corn, in comparison with the pea

The photochemical activities of chloroplasts isolated from bundle sheath and mesophyll cells of maize (Zea mays var. DS606A) have been measured. Bundle sheath chloroplasts are almost devoid of grana, except in very young leaves, while mesophyll chloroplasts contain grana at all stages of leaf

Maize (Zea mays L.) seedlings were grown in the presence or absence of an herbicide, norflurazon (4-chloro-5-(methylamino)-2-(α,α,α-trifluoro-m-tolyl)-pyridazinone), which prevents the accumulation of colored carotenoids. In the absence of carotenoids, plants grown in high light incur extensive

The appearance of photosynthetic proteins was directly measured in developing maize (Zea mays L.) leaves. Third leaves of 10-14-d-old seedlings were dissected into six successive sections from the basal meristem to the tip of the leaf. The membrane and soluble proteins were separated by

The pH dependence of the photoreduction of ferricyanide and the photoreduction of NADP from water and photosystem I activity have been compared in isolated chloroplasts from mesophyll and bundle sheath cells of Zea mays. The maximum activity of photoreduction of ferricyanide occurs at pH 8.5 in

Photoreduction of NADP from water in agranal chloroplasts isolated from the leaf bundle sheath cells of Zea mays (var. DS 606A) or Sorghum bicolor (var. Texas 610) was dependent upon addition of plastocyanin as well as ferredoxin. Activity was further increased by the addition of ferredoxin
