Transcriptomic and physiological analysis of common duckweed Lemna minor responses to NH4+ toxicity

摘要

BackgroundPlants can suffer ammonium (NH4⁺) toxicity, particularly when NH4⁺ is supplied as the sole nitrogen source. However, our knowledge about the underlying mechanisms of NH4⁺ toxicity is still largely unknown. Lemna minor, a model duckweed species, can grow well in high NH4⁺ environment but to some extent can also suffer toxic effects. The transcriptomic and physiological analysis of L. minor responding to high NH4⁺ may provide us some interesting and useful information not only in toxic processes, but also in tolerance mechanisms.
