DESCRIPTION:Light is one of the most important environmental cues controll
 ing  plant development and is achieved through a suite of photoreceptor  p
 roteins. Like photoreceptors associated with our vision\, plant  photosens
 ors can detect the presence\, intensity\, direction and colour  of light\,
  and in turn\, utilise this information to direct their  growth. To date\,
  four different types of photoreceptors have been  identified. Among them 
 is a small family of proteins known as the  phototropins (phot) that are a
 ctivated specifically by UV/blue  wavelengths of light. Photoactivation of
  these light-driven receptor  kinases stimulate a variety of processes tha
 t ultimately optimise the  photosynthetic efficiency of plants\, including
  phototropism after  which they were named. In particular\, photoregulatio
 n is mediate by a  small (~10 kDa) photosensory motif known as the LOV dom
 ain. The LOV  photosensory module is also present in a large number of oth
 erwise  very different bacterial proteins that are activated by blue light
 .  Progress in understanding the light sensing and signalling mechanisms  
 associated with plant phototropins and related proteins will be  discussed
  as will the development of novel applications for LOV-based  photosensors
