The ELF4 gene controls circadian rhythms and flowering time in Arabidopsis thaliana

Mark Robert Doyle, Seth J Davis, +5 authors Richard M Amasino
Nature
2002

Many plants use day length as an environmental cue to ensure proper timing of the switch from vegetative to reproductive growth. Day-length sensing involves an interaction between the relative length… (More)

The ELF3 zeitnehmer regulates light signalling to the circadian clock

Harriet G. McWatters, Ruth M. Bastow, Anthony Hall, Andrew J. Millar
Nature
2000

The circadian system regulates 24-hour biological rhythms and seasonal rhythms, such as flowering. Long-day flowering plants like Arabidopsis thaliana, measure day length with a rhythm that is not… (More)

ELF4 is required for oscillatory properties of the circadian clock.

Harriet G. McWatters, Elsebeth Kolmos, +6 authors Seth J Davis
Plant physiology
2007

Circadian clocks are required to coordinate metabolism and physiology with daily changes in the environment. Such clocks have several distinctive features, including a free-running rhythm of… (More)

The TIME FOR COFFEE gene maintains the amplitude and timing of Arabidopsis circadian clocks.

Anthony Hall, Ruth M. Bastow, +8 authors Andrew J. Millar
The Plant cell
2003

Plants synchronize developmental and metabolic processes with the earth's 24-h rotation through the integration of circadian rhythms and responses to light. We characterize the time for coffee (tic)… (More)

Constructing a feedback loop with circadian clock molecules from the silkmoth, Antheraea pernyi.

Dennis C. Chang, Harriet G. McWatters, Julie A. Williams, Anthony L. Gotter, Joel D Levine, Steven M. Reppert
The Journal of biological chemistry
2003

Circadian clocks are important regulators of behavior and physiology. The circadian clock of Drosophila depends on an autoinhibitory feedback loop involving dCLOCK, CYCLE (also called dBMAL, for… (More)

Sensitive to freezing6 integrates cellular and environmental inputs to the plant circadian clock.

Heather Knight, Adrian Thomson, Harriet G. McWatters
Plant physiology
2008

The sensitive to freezing6 (sfr6) mutant of Arabidopsis (Arabidopsis thaliana) is late flowering in long days due to reduced expression of components in the photoperiodic flowering pathway in… (More)

Fitness costs of disrupting circadian rhythms in malaria parasites

Aidan J O'Donnell, Petra Schneider, Harriet G. McWatters, Sarah E. Reece
Proceedings. Biological sciences
2011

Circadian biology assumes that biological rhythms maximize fitness by enabling organisms to coordinate with their environment. Despite circadian clocks being such a widespread phenomenon,… (More)

Homeostasis of plasma membrane viscosity in fluctuating temperatures.

Alexandre Martinière, Maria Shvedunova, +4 authors Harriet G. McWatters
The New phytologist
2011

Temperature has a direct effect at the cellular level on an organism. For instance, in the case of biomembranes, cooling causes lipids to lose entropy and pack closely together. Reducing temperature… (More)

SENSITIVE TO FREEZING 6 Integrates Cellular and Environmental Inputs to the Plant Circadian Clock 1 [ W ] [ OA ]

Heather Knight, Adrian Thomson, Harriet G. McWatters
2008

The sensitive to freezing6 (sfr6) mutant of Arabidopsis (Arabidopsis thaliana) is late flowering in long days due to reduced expression of components in the photoperiodic flowering pathway in… (More)

Defining the robust behaviour of the plant clock gene circuit with absolute RNA timeseries and open infrastructure

Anna Flis, Aurora Piñas Fernández, +11 authors Andrew J. Millar
Open biology
2015

Our understanding of the complex, transcriptional feedback loops in the circadian clock mechanism has depended upon quantitative, timeseries data from disparate sources. We measure clock gene RNA… (More)
