genetics of phytohormone responses

our knowledge about the mechanisms of signal transduction pathways triggered by plant hormones has dramatically increased within the last decade or so. some pathways, such as auxin signaling seem to be resolved from perception to gene expression. however, the multitude of different responses triggered by the same molecule is as amazing as it is poorly understood. hormone-induced expression of sometimes hundreds of genes seems to be a key aspect of these responses. but which genes or clusters of genes are responsible for which responses? why do ecotypes from different geographical and climatic backgrounds respond differently to the hormone stimulus ... and what are the genetic factors underlying this variation?
