chloroplast
movements (11) and stomatal aperture control (11, 18). The
remaining four proteins either are involved in other phot1-dependent
processes (V. faba phot1A-interacting protein and the
14-3-3 protein) (13, 14) or are not absolutely necessary for progression
of phot1-dependent phototropic signaling (RPT2 and
PKS1) (11, 12).
