Abstract
N-Acyl-D/L-homoserine lactones (AHLs) are produced as microbial signaling compounds during bacterial intra- and inter-specific communication in the rhizosphere. Thus, plants are naturally exposed to these compounds and respond with tissue-specific reactions. In the present study the impact of AHLs on the monocot barley (Hordeum vulgare L.) was investigated. The treatment with C8- and C12- homoserine lactones (HSL) resulted in root and shoot biomass gain as well as in the formation of lateral roots. It is assumed that nitric oxide (NO) has an impact on the lateral root formation. Both AHL derivatives induced the accumulation of NO in the root tissue, while the C1...
