Transcription profiling by array of Lotus japonicus wildtype and Ljgln2-2 mutant plants to investigate photorespiration


ABSTRACT: Wildtype and mutant plants lacking the plastidic isoform of glutamine synthetase were grown under CO2-enriched atmosphere and then transferred to low CO2 conditions. Transcriptomic profiling was carried out for plants under CO2-enriched atmosphere and plants after 2 days of transfer to low CO2 conditions.

The transcriptomic and metabolic consequences of the lack of plastidic glutamine (Gln) synthetase in the model legume Lotus japonicus were investigated. Wild-type and mutant plants lacking the plastidic isoform of Gln synthetase were grown in conditions that suppress photorespiration and then transferred for different lengths of time to photorespiratory conditions. Transcript and metabolite levels were determined at the different time points considered. Under photorespiratory active conditions,  ...[more]
