Roles of different phytochromes in Arabidopsis photomorphogenesis
Abstract
The red/far‐red light‐absorbing phytochromes play fundamental roles in photoperception of the light environment and the subsequent adaptation of plant growth and development. Higher plants possess multiple, discrete phytochromes, the apoproteins of which are the products of a family of divergent (PHY) genes. Arabidopsis thaliana has at least five PHY genes, encoding the apoproteins of phytochromes A‐E. Through the analysis of mutants that are deficient in phytochrome A or B and the corresponding double mutant, it is becoming clear that these phytochromes perform both discrete and overlapping roles throughout plant development. Through analysis of the phyA phyB double mutant, it has been possible to define several responses that are mediated by other members of the phytochrome family. This article reviews some of the recent progress in the study of phytochrome‐deficient mutants of the model plant Arabidopsis thaliana.

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.
