Time for growth.

Plants measure the duration of metabolic activity to promote rapid growth in long days.

A bittersweet symphony: Metabolic signals in the circadian system.

Plants must match their metabolism to daily and seasonal fluctuations in their environment to maximise performance in natural conditions. Circadian clocks enable organisms to anticipate and adapt to these predictable and unpredictable environmental challenges. Metabolism is increasingly recognised as an integrated feature of the plant circadian system.

A reactive oxygen species Ca signalling pathway identified from a chemical screen for modifiers of sugar-activated circadian gene expression.

Sugars are essential metabolites for energy and anabolism that can also act as signals to regulate plant physiology and development. Experimental tools to disrupt major sugar signalling pathways are limited. We performed a chemical screen for modifiers of activation of circadian gene expression by sugars to discover pharmacological tools to investigate and manipulate plant sugar signalling.

Pores for Thought: Can Genetic Manipulation of Stomatal Density Protect Future Rice Yields?

Rice ( L.) contributes to the diets of around 3.5 billion people every day and is consumed more than any other plant.
