Abstract

The transition from vegetative to reproductive development is regulated by several environmental cues, including light quality, photoperiod and temperature. In Arabidopsis a strong correlation has been observed between the response to vernalisation and the response to low R:FR ratio light in the acceleration of flowering. In preliminary work we have found that vrn mutants, impaired in the vernalisation response, show altered responses to low R:FR ratio. This suggests that perhaps the R:FR and cold signalling pathways are interconnected or that the VRN gene products act independently in both pathways. Here, we propose to analyse the photophysiology of vrn2 mutants, and transgenic plants with altered expression of VRN2, to determine the extent of the interconnection of the signalling pathways.
