- ... MAIN CONCLUSION : A large proportion of genes in plant genomes are organized as gene families. Whereas most gene families in the aquative plant Spirodela are reduced in their copy number, the PPR gene family is expanded, which match the RNA editing sites in organelles, providing us with new insights in the evolution of flowering plants. Pentatricopeptide-repeat proteins (PPRs) are nuclear-encoded ...

- ... Activities of NADP-dependent isocitrate dehydrogenases (cytosolic and plastidic isoforms, ICDH1 and ICDH2; EC 18.104.22.168) and ferredoxin-dependent glutamate synthase (Fd-GOGAT; EC 22.214.171.124) in turions of Spirodela polyrhiza were all stimulated by light. Single or repeated red light (R) pulses induced the activity of the enzymes and this effect was reverted by subsequent far-red light (FR) pulses. The ...
