Crotalaria spectabilis | exogenously applied nitrate has no impact on polyamine biosynthesis, and enzyme expression | additional information |
Crotalaria spectabilis | polymanines in Crotalaria are detectable only when the plants form nodules after infection with their rhizobial partner, nodulation is induced by infection with a Bradyrhizobium strain and triggers the polyamine biosynthesis, leading to induction of the enzyme HSS in nodules | up |
General Information | Comment | Organism |

metabolism | polymanines in Crotalaria are detectable only when the plants form nodules after infection with their rhizobial partner. But polyamines are synthesized by the plant not by the mcirosymbiont | Crotalaria spectabilis |
additional information | exogenously applied nitrate has no impact on polyamine biosynthesis, and enzyme activity, but nodulation is inhibited at higher levels of nitrate by autoregulation | Crotalaria spectabilis |
