Abstract

G Gardner and HL Gorton (1985 Plant Physiol 77: 540) demonstrated that gabaculine (5-amino-1,3-cyclohexadienylcarboxylic acid) inhibits the initial synthesis and resynthesis of spectrophotometrically detectable phytochrome in pea, maize, and oat. We show that the level of immuno-detectable phytochrome in pea is unaffected by the presence of gabaculine at a concentration that reduces spectrophotometrically detectable phytochrome up to 10-fold. This result indicates that gabaculine inhibits chromophore synthesis without affecting phytochrome apoprotein synthesis and that chromophore-less phytochrome is stable in the cell.
