Abstract

Changes in the carotenoid content of spinach and lima bean leaf segments were studied under various conditions. Under intense light in N2, a decrease in the violaxanthin concentration was accompanied by a nearly stoichiometric increase in zeaxanthin. This light reaction was accompanied by a transient increase and decrease in the antheraxanthin concentration. In spinach when exposure to strong light in N2 was followed by dark incubation in O2, there was a decrease of zeaxanthin, an increase in antheraxanthin, and a small increase in violaxanthin. In the case of bean leaf, the decrease in zeaxanthin was accompanied by a nearly stoichiometric increase in antheraxanthin. The concentrations of lutein, neoxanthin, and carotene remained constant or changed only slightly throughout these experiments. These results suggest the following relationship of the β-carotene-derived xanthophylls: .

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.
