Journal ArticleDOI
Plant Circadian Clocks Increase Photosynthesis, Growth, Survival, and Competitive Advantage
Antony N. Dodd,Neeraj Salathia,Neeraj Salathia,Anthony Hall,Anthony Hall,Éva Kevei,Éva Kevei,Éva Kevei,Réka Tóth,Ferenc Nagy,Julian M. Hibberd,Andrew J. Millar,Andrew J. Millar,Alex A. R. Webb +13 more
TL;DR: It is shown that a substantial photosynthetic advantage is conferred by correct matching of the circadian clock period with that of the external light-dark cycle, which explains why plants gain advantage from circadian control.
Journal ArticleDOI
ABI1 Protein Phosphatase 2C Is a Negative Regulator of Abscisic Acid Signaling
Françoise Gosti,Nathalie Beaudoin,Carine Serizet,Alex A. R. Webb,Nicole Vartanian,Jérôme Giraudat +5 more
TL;DR: Results indicate that a loss of ABI1 PP2C activity leads to an enhanced responsiveness to ABA, and that the wild-type ABA1 phosphatase is a negative regulator of ABA responses.
Journal ArticleDOI
The short-period mutant, toc1-1, alters circadian clock regulation of multiple outputs throughout development in Arabidopsis thaliana
TL;DR: A new set of circadian clock-controlled phenotypes for Arabidopsis thaliana are reported, consistent with the likelihood that TOC1 codes for an oscillator component rather than for an element of an input signaling pathway, and indicate that T OC1 acts on or within the clock independently of light input.
Journal ArticleDOI
Stimulus-induced oscillations in guard-cell cytosolic-free calcium
TL;DR: A mechanism for encoding the information required to distinguish between a number of different Ca2+-mobilizing stimuli in guard cells, using stimulus-specific patterns of oscillations in [Ca2+]i is suggested.
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.
