Abstract

Nitric oxide (NO) is a membrane permeable gaseous free radical and in biological system it rapidly reacts with oxygen (O2), superoxide (O2-), thiols and heme-proteins. According to the reactivity of NO, it is thought that in biological system NO could be a signal molecule. In plants NO plays a key role of many important physiological process (disease resistance, stomatal movement, floral transition and so on). However, little is known about molecular mechanisms of NO signaling in plants. For studying the role of NO, we produced transgenic Arabidopsis plants overexpressing nitric oxide synthase from Deinococcus radiodurans. The growth of the NOS transgenic plants was much slow and the shape of rosette leaves of this transgenic plants was different from WT. Number of lateral stem from primary stem in this transgenic plants was much larger than that of WT.
