Blue-light photoreceptors and development of the garden pea

TL;DRAbstract

Developmental responses of plants to their light environment are of obvious importance to their fitness and survival, and plant photomorphogenesis has been the focus of much study over the past decade. Great advances have been made in our understanding of the photoreceptors involved in photomorphogenic responses, their roles, their biochemical and photochemical nature, and signal transduction processes initiated by the activated photoreceptors. Much of this study has been focussed on the red/far-red phytochrome photoreceptors, for which mutants have now been isolated in a number of model species. The cryptochrome photoreceptors are comparatively less well characterised, with mutants so far only identified in the Arabidopsis CRYJ and CRY2 genes, and the tomato CRY1a gene. The aim of the current research was to extend the characterisation of the structure and function of the cryptochrome gene family to include another major member of the eudicots, the Fabaceae, represented by the garden
