Using ‘mute’ plants to translate volatile signals
Abstract
When attacked by herbivores, plants release volatile organic compounds (VOCs) that attract natural enemies of the herbivores and function as indirect defenses. Whether or not neighboring plants 'eavesdrop' on these VOCs remains controversial because most studies use unrealistic experimental conditions and VOC exposures. In order to manipulate exposures of wild-type (WT) Nicotiana attenuata'receiver' plants, we elicited transformed 'emitter' plants, whose production of herbivore-induced C6 green leaf volatiles (GLVs) or terpenoid volatiles was genetically silenced, and placed them up-wind of WT 'receiver' plants in open-flow experimental chambers. We compared the transcriptional and secondary metabolite defense responses of WT receiver plants exposed to VOCs from these transgenic emitter plants with those of plants exposed to VOCs from WT emitter plants. No differences in the constitutive accumulation of defense metabolites and the signal molecule jasmonic acid (JA) were found. Additional elicitation of receiver plants revealed that exposure to WT, GLV-deficient and terpenoid-deficient volatile blends did not prime induced defenses, JA accumulation, or the expression of lipoxygenase 3 (NaLOX3), a gene involved in JA biosynthesis. However, exposure to wound- and herbivore-induced VOCs significantly altered the transcriptional patterns in receiver plants. We identified GLV-dependent genes by complementing the GLV-deficient volatile blend with a mixture of synthetic GLVs. Blends…

“Further support for the potential regulatory role of defense volatiles comes from LOX2-silenced Nicotiana attenuata plants, which are deficient in the production of herbivory-induced, greenleaf volatiles.In contrast with the other systems where volatiles induce defense, the LOX2 mutation leads to stronger expression of defense-related genes in neighbors than wild-type plants, suggesting that volat”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
