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 immunodetectable 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.This publication has 8 references indexed in Scilit:
