UV-B perception and signalling in plants
Plant Molecular Biology
Sunlight is of utmost importance to plants, not only as energy source but also as an environmental signal regulating growth and development. An important and increasing part of the incident sunlight encompasses a segment of the ultraviolet-B region (UV-B; 280-315 nm) that is not entirely absorbed by the ozone layer in the stratosphere of the Earth. UV-B radiation is potentially harmful for any organism exposed to it, but is also used as an informational signal for which plants have evolved specific and sensitive UV-B perception systems promoting UV-B acclimation and tolerance. Our understanding of this UV-B sensory pathway is presently limited to a small number of major players, and even less is known on their interplay, regulations and mechanisms of action. The major aim of our laboratory is a better understanding of UV-B perception and signalling in plants that leads to UV-B acclimation and survival.
