Resumen:
Light and temperature are arguably the most important variables of the environment providing cues for the adjustment of plant body form and function to the prevailing conditions. Light and temperature changes represent both a challenge and an opportunity for plants; a challenge, because they can generate physiological stress; an opportunity, because the anticipated perception of changes in the environment provides information that helps plants to adjust to the incoming stressful conditions.  Phytochromes and cryptochromes are the main plant photoreceptors. Downstream signalling involves a complex network where the photoreceptors repress negative regulators of photomorphogenesis. These pathways are connected to the hormone signalling pathways, creating complex networks that link light signals to physiological responses. Our current interest is to understand the molecular mechanisms by which plants can integrate different environmental signals controlling the shape and function of their body.
