Volatile Signaling in Plant-Plant Interactions: "Talking Trees" in the Genomics Era
Abstract
Plants may "eavesdrop" on volatile organic compounds (VOCs) released by herbivore-attacked neighbors to activate defenses before being attacked themselves. Transcriptome and signal cascade analyses of VOC-exposed plants suggest that plants eavesdrop to prime direct and indirect defenses and to hone competitive abilities. Advances in research on VOC biosynthesis and perception have facilitated the production of plants that are genetically "deaf" to particular VOCs or "mute" in elements of their volatile vocabulary. Such plants, together with advances in VOC analytical instrumentation, will allow researchers to determine whether fluency enhances the fitness of plants in natural communities.

Volatile secondary metabolites such as terpenoids, green-leaf volatiles, and aromatic compounds can also regulate plant defenses.
“Apart from glucosinolates and benzoxazinoids, volatile secondary metabolites such as terpenoids, green-leaf volatiles, and aromatic compounds can also regulate plant defenses (Baldwin et al., 2006;Godard et al., 2008;Erb, 2018;Bouwmeester et al., 2019).”

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.
