This process has been linked to the degradation of IAA19, which binds to and inactivates certain transcriptional regulators.
This process has been linked to the degradation of IAA19, which binds to and inactivates certain transcriptional regulators. Those regulators, ARFs, may promote this process by controlling the expression of genes containing auxin response elements. Some mutants unable to perform this process contain lower levels of a protein whose domains bind to flavin chromophores. That namesake protein is autophosphorylated in response to a certain stimulus, resulting in accumulation of the hormone auxin in areas where the stimulus is absent. For 10 points, name this process that occurs under blue light and is principally controlled by the plant protein phototropin.
