    PKS1, a substrate phosphorylated by phytochrome that modulates light signaling in Arabidopsis (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-05-29
    Description: Plants constantly monitor their light environment in order to grow and develop optimally, in part through use of the phytochromes, which sense red/far-red light. A phytochrome binding protein, PKS1 (phytochrome kinase substrate 1), was identified that is a substrate for light-regulated phytochrome kinase activity in vitro. In vivo experiments suggest that PKS1 is phosphorylated in a phytochrome-dependent manner and negatively regulates phytochrome signaling. The data suggest that phytochromes signal by serine-threonine phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fankhauser, C -- Yeh, K C -- Lagarias, J C -- Zhang, H -- Elich, T D -- Chory, J -- R01GM52413/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 May 28;284(5419):1539-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Biology Laboratory, Howard Hughes Medical Institute, Salk Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10348744" target="_blank"〉PubMed〈/a〉

    A cyanobacterial phytochrome two-component light sensory system (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-09-05
    Description: The biliprotein phytochrome regulates plant growth and developmental responses to the ambient light environment through an unknown mechanism. Biochemical analyses demonstrate that phytochrome is an ancient molecule that evolved from a more compact light sensor in cyanobacteria. The cyanobacterial phytochrome Cph1 is a light-regulated histidine kinase that mediates red, far-red reversible phosphorylation of a small response regulator, Rcp1 (response regulator for cyanobacterial phytochrome), encoded by the adjacent gene, thus implicating protein phosphorylation-dephosphorylation in the initial step of light signal transduction by phytochrome.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yeh, K C -- Wu, S H -- Murphy, J T -- Lagarias, J C -- 1 P41 RR06009/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1997 Sep 5;277(5331):1505-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section of Molecular and Cellular Biology, University of California, Davis, CA 95616, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9278513" target="_blank"〉PubMed〈/a〉
