Journal ArticleDOI
Genetics of Aux/IAA and ARF action in plant growth and development.
Emmanuel Liscum,Jason W. Reed +1 more
TL;DR: A review of mutations that affect auxin-modulated transcription factors, in particular those in the Aux/IAA and AUXIN RESPONSE FACTOR(ARF) genes, and potential mechanisms for interactions between auxin and light response pathways suggested by these mutants.
Journal ArticleDOI
Arabidopsis NPH1: A Protein Kinase With a Putative Redox-Sensing Domain
TL;DR: The NPH1 (nonphototropic hypocotyl 1) gene encodes an essential component acting very early in the signal-transduction chain for phototropism as discussed by the authors.
Journal ArticleDOI
Arabidopsis NPH1: A Flavoprotein with the Properties of a Photoreceptor for Phototropism
John M. Christie,Philippe Reymond,Gary Keith Powell,Paul Bernasconi,Andrei A. Raibekas,Emmanuel Liscum,Winslow R. Briggs +6 more
TL;DR: The fluorescence excitation spectrum of the recombinant protein is similar to the action spectrum for phototropism, consistent with the conclusion that NPH1 is an autophosphorylating flavoprotein photoreceptor mediating phototropic responses in higher plants.
Journal ArticleDOI
Mutations in the NPH1 Locus of Arabidopsis Disrupt the Perception of Phototropic Stimuli
TL;DR: It appears that the NPH1 protein is most likely a 120-kD plasma membrane-associated phosphoprotein because all of the nph1 mutations negatively affected the abundance of this protein, providing strong support for the hypothesis that more than one blue light photoreceptor is required for the normal growth and development of a seedling.
Journal ArticleDOI
MASSUGU2 Encodes Aux/IAA19, an Auxin-Regulated Protein That Functions Together with the Transcriptional Activator NPH4/ARF7 to Regulate Differential Growth Responses of Hypocotyl and Formation of Lateral Roots in Arabidopsis thaliana
Kiyoshi Tatematsu,Satoshi Kumagai,Hideki Muto,Atsuko Sato,Masaaki K. Watahiki,Reneeé M. Harper,Emmanuel Liscum,Kotaro T. Yamamoto +7 more
TL;DR: Results suggest that MSG2/IAA19 and NPH4/ARF7 may constitute a negative feedback loop to regulate differential growth responses of hypocotyls and lateral root formation.
