Reproductive abnormalities in SDH1-1/sdh1-1 mutant plants. A, Mature pollen grains from a wild-type plant. Bar = 20 μm. B, Mature pollen grains from a heterozygous mutant plant. A substantial proportion of pollen grains are collapsed (arrowheads). Bar = 20 μm. C, Mature siliques of a SDH1-1/sdh1-1 plant are shorter and contain less seeds than mature siliques of the wild type. Bar = 2 mm. D, Closeup of a developing SDH1-1/sdh1-1 silique. Arrowheads denote aborted, white, and shrunken ovules. A wild-type seed is indicated by an asterisk. E, Seed set is reduced in SDH1-1/sdh1-1 siliques. Seed set per silique was scored along the main inflorescence axis for six T3 Kanr SDH1-1/sdh1-1 plants and two wild-type plants. Silique 1 (first, older flower) to silique 16 were grouped in four groups of four siliques for each plant. Total counts of 28.2 and 18.9 seeds/silique were obtained for wild type and SDH1-1/sdh1-1 plants, respectively (last two bars). Error bars are sds.
