Journal ArticleDOI
Early abscisic acid signal transduction mechanisms: newly discovered components and newly emerging questions
Katharine E. Hubbard,Noriyuki Nishimura,Kenichi Hitomi,Elizabeth D. Getzoff,Julian I. Schroeder +4 more
TL;DR: An emerging PYR/RCAR-PP2C-SnRK2 model of ABA signal transduction provides researchers with a framework through which early ABA signaling can be understood, and allow novel questions about the hormone response pathway and possible applications in stress resistance engineering of plants to be addressed.
Journal ArticleDOI
Photosynthetic entrainment of the Arabidopsis thaliana circadian clock
Michael J. Haydon,Olga Mielczarek,Fiona C. Robertson,Fiona C. Robertson,Katharine E. Hubbard,Alex A. R. Webb +5 more
TL;DR: It is demonstrated that endogenous oscillations in sugar levels provide metabolic feedback to the circadian oscillator through the morning-expressed gene PSEUDO-RESPONSE REGULATOR 7 (PRR7), and that prr7 mutants are insensitive to the effects of sucrose on the circadian period.
Journal ArticleDOI
Modulation of environmental responses of plants by circadian clocks
Carlos Takeshi Hotta,Michael J. Gardner,Katharine E. Hubbard,Seong Jin Baek,Neil Dalchau,Dontamala Suhita,Antony N. Dodd,Alex A. R. Webb +7 more
TL;DR: How environmental rhythms of temperature and light intensity entrain the circadian clock, how photoperiodism may be regulated by the relationship between environmental rhythms and the phasing of clock outputs, and how gating modulates the sensitivity of the clock and other responses to environmental and physiological signals are described.
Journal ArticleDOI
The Arabidopsis circadian clock incorporates a cADPR-based feedback loop
Antony N. Dodd,Michael J. Gardner,Michael J. Gardner,Carlos Takeshi Hotta,Carlos Takeshi Hotta,Katharine E. Hubbard,Katharine E. Hubbard,Neil Dalchau,Neil Dalchau,John Love,John Love,Jean-Maurice Assie,Jean-Maurice Assie,Fiona C. Robertson,Fiona C. Robertson,Mia Kyed Jakobsen,Mia Kyed Jakobsen,Jorge Goncalves,Dale Sanders,Dale Sanders,Alex A. R. Webb,Alex A. R. Webb +21 more
TL;DR: It is shown that the plant circadian clock also incorporates the cytosolic signaling molecule cyclic adenosine diphosphate ribose (cADPR), which modulates the circadian oscillator's transcriptional feedback loops and drives circadian oscillations of Ca2+ release.
Journal ArticleDOI
How plants tell the time.
TL;DR: The advances in determining the molecular nature of the circadian oscillator are described and an architecture of several interlocking negative-feedback loops is proposed and the adaptive advantages of circadian control, with particular reference to the regulation of metabolism, are considered.
