Název v původním jazyce

Response of Arabidopsis thaliana to N-hexanoyl-DL-homoserine-lactone, a bacterial quorum sensing molecule produced in the rhizosphere

Popis výsledku v původním jazyce

The bacterial quorum sensing signals N-acyl-L-homoserine lactones enable bacterial cells to regulate gene expression depending on population density, in order to undertake collective actions such as the infection of host cells. Only little is known aboutthe molecular ways of plants reacting to these bacterial signals. In this study we show that the contact of Arabidopsis thaliana roots with N-hexanoyl-DL-homoserine-lactone (C6-HSL) resulted in distinct transcriptional changes in roots and shoots, respectively. Interestingly, unlike most other bacterial signals, C6-HSL influenced only a few defense-related transcripts. Instead, several genes associated with cell growth as well as genes regulated by growth hormones showed changes in their expression after C6-HSL treatment. C6-HSL did not induce plant systemic resistance against Pseudomonas syringae. The inoculation of roots with different types of AHLs led predominantly for short chain N-butyryl-DLhomoserine lactone and C6-HSL to root e
