Characterization of photosynthesis in rice wild-type (WT) and Osfc24 mutant plants. (A) Leaf extracts show defects in the chloroplasts of the mutant, which may derive from a lack of flux of UDP-Gal into the galactolipids of the chloroplasts when the plants are engaged in photosynthesis. (B) Quantification of galactoses released from galactolipids for plants of different ages. (C) Contents of chloroplast pigments and (D) photosynthetic rate of leaves of 60-d-old plants, (E) content of soluble sugars of mature stems, and (F) biomass of mature plants. Data are means (±SD) of either three replicates (B, C, E), n≥12 replicates (D; the uppermost leaves were measured), or n≥20 mature plants (F). Significant differences between the WT and mutant were determined using Student’s t-test: **P<0.01. Percentage changes relative to the WT are indicated.
