Succinate dehydrogenase mutant plants


ABSTRACT: In this experiment we used leaves from 6-week-old Arabidopsis SDH1-1/sdh1-1 mutant and Wt plants (Ws). The leaves were collected in the middle of light period.

Mitochondrial complex II (succinate dehydrogenase [SDH]) plays roles both in the tricarboxylic acid cycle and the respiratory electron transport chain. In Arabidopsis (Arabidopsis thaliana), its flavoprotein subunit is encoded by two nuclear genes, SDH1-1 and SDH1-2. Here, we characterize heterozygous SDH1-1/sdh1-1 mutant plants displaying a 30% reduction in SDH activity as well as partially silenced plants obtained by RNA interference. We found that these plants displayed significantly higher C  ...[more]
