We have investigated the biochemical basis for this lack of function. When the hy1 and hy2 mutants were grown in white light on a medium containing biliverdin IX[alpha], a direct precursor to phytochromobilin, the phytochrome chromophore, the seedlings developed with a morphological phenotype indistinguishable from the light-grown wild-type control. Restoration of a light-grown phenotype in the hy1 mutant was also accomplished by using phycocyanobilin, a tetrapyrrole analog of phytochromobilin. Spectrophotometric and immunochemical analyses of the rescued hy1 and hy2 mutants demonstrated that they possessed wild-type levels of photochemically functional phytochrome that displayed light-induced conformational changes in the holoprotein indistinguishable from the wild type. Moreover, phytochrome A levels declined in vivo in response to white light in rescued hy1 and hy2 seedlings, indicative of biliverdin-dependent formation of photochemically functional phytochrome A that was then subject to normal selective turnover in the far-red-light-absorbing form. Combined, these data suggest that the hy1 and hy2 mutants are inhibited in chromophore biosynthesis at steps prior to the formation of biliverdin IX[alpha], thus potentially causing a global functional deficiency in all members of the phytochrome photoreceptor family."xsd:string |
