Abstract/OtherAbstract:
The identity and number of the lipases involved in the activation of oxylipin biosynthesis remain controversial. In this study we demonstrate that NaGLA1 in Nicotiana attenuata is a specific supplier of trienoic fatty acids for JA biosynthesis in leaves and roots after wounding and simulated herbivory and that it utilizes multiple glycerolipid substrates as a source of trienoic fatty acids. Alternative functions for NaGLA1 were revealed by the analysis of the regulation of NaDES1 and NaLOX1 gene expression and divinyl ether metabolism during pathogen infection. We propose that distinct lipases control the activation of specific oxylipin biosynthesis pathways and that these lipases are activated by distinct stimuli.
