Phytochrome E Influences Internode Elongation and Flowering Time in Arabidopsis
Open accessAbstract
From a screen of M2 seedlings derived from gamma-mutagenesis of seeds doubly null for phytochromes phyA and phyB, we isolated a mutant lacking phyE. The PHYE gene of the selected mutant, phyE-1, was found to contain a 1-bp deletion at a position equivalent to codon 726, which is predicted to result in a premature stop at codon 739. Immunoblot analysis showed that the phyE protein was undetectable in the phyE-1 mutant. In the phyA- and phyB-deficient background, phyE deficiency led to early flowering, elongation of internodes between adjacent rosette leaves, and reduced petiole elongation. This is a phenocopy of the response of phyA phyB seedlings to end-of-day far-red light treatments. Furthermore, a phyE deficiency attenuated the responses of phyA phyB seedlings to end-of-day far-red light treatments. Monogenic phyE mutants were indistinguishable from wild-type seedlings. However, phyB phyE double mutants flowered earlier and had longer petioles than did phyB mutants. The elongation and flowering responses conferred by phyE deficiency are typical of shade avoidance responses to the low red/far-red ratio. We conclude that in conjunction with phyB and to a lesser extent with phyD, phyE functions in the regulation of the shade avoidance syndrome.

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.
