Article Synopsis
- N-acyl-homoserine lactones (AHLs), like N-decanoyl-L-homoserine lactone (C10-HSL), impact plant growth and disease resistance, particularly inhibiting primary root growth in Arabidopsis.
- Treatment with C10-HSL causes an immediate increase in cytosolic free calcium and reactive oxygen species (ROS), and activates the mitogen-activated protein kinase (MPK6), leading to nitric oxide (NO) production that is linked to root growth inhibition.
- The study reveals that calcium, ROS, MPK6, and NO are interconnected in the signaling pathway initiated by C10-HSL, with MPK6 being essential for mediating the inhibitory effects on root development.
Background: N-acyl-homoserine lactones (AHLs) are the quorum sensing (QS) signal molecules to coordinate the collective behavior in a population in Gram-negative bacteria. Recent evidences demonstrate their roles in plant growth and defense responses.
Results: In present study, we show that the treatment of plant roots with N-3-oxo-hexanoyl-homoserine lactone (3OC6-HSL), one molecule of AHLs family, resulted in enhanced salt tolerance in Arabidopsis and wheat.
In the present study, a AHL-utilizing strain RI was isolated and identified as the genus Rhodosporidium toruloides R1 by physi-biochemical approaches and 18S rDNA sequence analysis, and this strain was designated as R. toruloides R1. Results showed that R.

A glutamate: succinate semialdehyde transaminase gene from Escherichia coli, a glutamate decarboxylase gene from E. coli, and a 4-hydroxybutyrate dehydrogenase gene from Ralstonia eutropha were cloned by PCR and assembled onto the plasmid pKSSE5.
