Abstract

The phytochromes enable plants to detect low R:FR ratio light reflected from neighbouring vegetation and to increase elongation growth and promote flowering; the shade avoidance syndrome. To gain insights into the shade avoidance signalling pathway Arabidopsis microarrays and natural allelic variation have been exploited. PIL1, a novel bHLH transcription factor responds rapidly and reversibly to R:FR ratio. The expression of PIL1 in response to low R:FR ratio is modulated in a circadian manner, as are some shade avoidance responses. Ectopic overexpression of PIL1 leads to aberrant shade avoidance responses. The expression and functions of PIL1 will be analysed. Novel QTLs have been identified that selectively affect the shade avoidance flowering responses. These will be fine-mapped and the relevant genes identified.
