Abstract

There is now general agreement that nitric oxide (NO) is an important and almost universal signal in plants. Nevertheless, there are still many controversial observations and opinions on the importance and function of NO in plants. Partly, this may be due to the difficulties in detecting and even more in quantifying NO. Here, we summarize major pathways of NO production in plants, and briefly discuss some methodical problems.

Keywords: DAF-fluorescence; NO detection; NO signaling; chemiluminescence; mitochondria; nitrate reductase; nitric oxide; nitric oxide synthase.
