Transcriptomicsntr-Transcriptomic study of a thioredoxin reductase knock-out mutant.
rs04-02_ntr - ntr - Thioredoxins are small redox proteins implicated in crucial pathways of cell life. They are reduced by a conserved flavoprotein named NADPH-dependent thioredoxin reductase (NTR). In order to give an insight into the functions of the NTR/thioredoxin pathway in Arabidopsis, we have...
