Leaf Isoprene Emission Rate Is Dependent on Leaf Development and the Level of Isoprene Synthase
Open accessAbstract
Isoprene (2-methyl-1,3-butadiene) is a major volatile hydrocarbon produced by many plant species. Here we report that in velvet bean (Mucuna sp.), isoprene emission is strongly dependent on leaf developmental state and that changes in extractable isoprene synthase activity parallel isoprene emission rates during leaf development. Both leaf emission and enzyme activity exhibit over 100-fold increases from leaf emergence to leaf age 14 d and exhibit similar patterns to 23 d. This suggests that the enzyme, isoprene synthase, is responsible for the in vivo production of isoprene and that the level of the enzyme regulates the pattern of isoprene emission in response to leaf development.

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.
