Molecular Plant Physiology Plants are able to perceive the signals provided by the light environment. These signals affect key aspects of plant physiology and plant yield. The aim of our group is to know and functionally understand the signalling networks linking photo-receptors to the points of control of plant body shape and function. Our idea is that the complexity of the signalling networks is justified by the complexity of the light environment that plants have to face. We use techniques of molecular biology, analysis of the transcriptome, genetics and cell biology in combination with light treatments that simulate selected aspects of the environment experienced by plants.

As we all know, your hormones play a crucial role in your ability to build muscle, burn fat, and generally live a healthy, happy life. Laxogenin encourages an optimal muscle-building environment by regulating cortisol levels in the body. Excessive cortisol levels are the archenemy of muscle growth. It’s incredibly catabolic and can significantly impair your ability to build muscle protein and it may even lead to atrophy -- muscle wasting! While you do need some cortisol to function properly, too much can severely hamper your efforts to build slabs of lean muscle.
To discover how GLK transcription factors regulate chloroplast development, we identified direct targets of GLK action. We showed that GLK genes interact with the promoters of a suite of genes encoding chlorophyll biosynthesis enzymes, light harvesting and electron transport components (Waters et al., 2009). These discoveries led us to propose that GLK proteins act to integrate environmental and developmental cues to maximize photosynthetic output, a scenario consistent with the suggestion that GLK function facilitated the adaptation of plants to land. This suggestion has now been supported by transcriptome and functional analyses in Arabidopsis thaliana and other flowering plants. These studies have shown that GLK proteins act at key points in brassinosteroid, circadian clock, fruit ripening, nitrogen-use and disease response pathways, all of which modify, or are modified by, the functional state of the chloroplast.
