The cpftsy Mutant and ffc chaos Double Mutant Exhibit Similar Severe Phenotypic and Ultrastructural Alterations.
(A) Wild-type, double mutant ffc chaos, and cpftsy mutant plants are presented at the rosette stage.
(B) Pigments were extracted from the plant lines shown in (A) and analyzed as described in Methods. Data are mean values of five measurements ± sd. The scale (ng/mm2) for minor carotenoids is shown at right, and the scale for chlorophylls is given at left. antera, antheraxanthin; βcar, β-carotene; chla, chlorophyll a; chlb, chlorophyll b; lut, lutein; neo, neoxanthin; vio, violaxanthin; zea, zeaxanthin.
(C) Chloroplast ultrastructure was examined by electron microscopy using leaf sections from the plant lines shown in (A). Representative electron micrographs are shown. Bar = 1 μm.
