Growth in dense stands induces shade avoidance responses. Early responses to neighbors seem to be assoctaed with touch, not light signalling. We studied gene expression in petioles during early canopy development when leaf hyponasty was visible but altered phytochrome signalling was not yet detectab...
ORGANISM(S): Arabidopsis thaliana 
Low R:FR signaling through phytochromes induces shade avoidance responses, including petiole elongation. Salicylic acid-mediated defense against pathogens is inhibited under these conditions. Using microarrays we studied the crosstalk between low R:FR and SA at the global gene expression level in Ar...

Low reduced red:far-red ratio [R:FR] signaling through phytochromes induces shade avoidance responses, including petiole elongation. Jasmonic acid-mediated defense against herbivores and pathogens is inhibited under these conditions. Using microarrays we studied the crosstalk between low R:FR and JA...
