Abstract

The consequences of drought stress on the organization of chlorophyll into photosynthetic units and on the chlorophyll-protein composition of mesophyll and bundle sheath chloroplasts of Zea mays L. were studied. It was found that the majority of chlorophyll lost in response to water stress occurs in the mesophyll cells with a lesser amount being lost from the bundle sheath cells. All of the chlorophyll loss could be accounted for by reduction in the lamellar content of the light-harvesting chlorophyll a/b-protein, a rather specific target for water stress. The decreased content of this chlorophyll-protein accounts for the elevated chlorophyll a/b ratios and the reduced photosynthetic unit sizes of the two cell types in stressed plants. The implications of the selective catabolism of this major membrane component are discussed.
