“…Recent studies have reported that insect-induced plant volatiles can also function in planteplant communications, thereby volatiles emitted from insect-damaged plants can prime or activate defense responses in nearby healthy plants [39]. MeSA as an air-borne signal has been shown to mediate such inter-plant interactions in the context of planteviral interactions [36]. Incubation with the transgenic Arabidopsis plants overexpressing OsBSMT1, which has higher levels of MeSA emission, was sufficient to trigger PR-1 induction in neighboring wild-type plants [17], supporting the role of MeSA as an air-borne signal in planteplant communications.…”

“…This JA treatment led to rapid induction of WIPI-2 gene expression, while PRP6 expression was not induced. When plants are treated with MeSA, this will be converted in the plant to SA by demethylation (Shulaev et al 1997). This treatment led to activation of SA-responsive genes as could be seen from the induction of PRP6.…”

Two cDNAs encoding geranylgeranyl pyrophosphate (GGPP) synthases from tomato (Lycopersicon esculentum) have been cloned and functionally expressed in Escherichia coli. LeGGPS1 was predominantly expressed in leaf tissue and LeGGPS2 in ripening fruit and Xower tissue. LeGGPS1 expression was induced in leaves by spider mite (Tetranychus urticae)-feeding and mechanical wounding in wild type tomato but not in the jasmonic acid (JA)-response mutant def-1 and the salicylic acid (SA)-deWcient transgenic NahG line. Furthermore, LeGGPS1 expression could be induced in leaves of wild type tomato plants by JA-or methyl salicylate (MeSA)-treatment. In contrast, expression of LeGGPS2 was not induced in leaves by spider mite-feeding, wounding, JA-or MeSA-treatment. We show that emission of the GGPP-derived volatile terpenoid (E,E)-4,8,12-trimethyltrideca-1,3,7,11-tetraene (TMTT) correlates with expression of LeGGPS1. An exception was MeSA-treatment, which resulted in induction of LeGGPS1 but not in emission of TMTT. We show that there is an additional layer of regulation, because geranyllinalool synthase, catalyzing the Wrst dedicated step in TMTT biosynthesis, was induced by JA but not by MeSA.

“…The purpose of BVOCs appears to be to attract pollinators and herbivore predators, and to communicate with other plants and organisms [6,7]. But there is another function of BVOCs that has attracted interest given current climate warming.…”
