deficient mutants have been used as phytochrome-deficient plants
to study many aspects of plant development. However, there are
still a number of important questions to be resolved concerning
both the targets and the phenotypic consequences of these
mutations. Recently, progress has been made in our understanding
of the molecular basis of the chromophore deficiency in these
mutants. Biochemical assays for the committed steps of
chromophore synthesis have been developed and used to
demonstrate that the pcd1 and yellow-green-2 mutants of pea and
tomato, respectively, are unable to synthesize biliverdin IXα
from heme while pcd2 and aurea are deficient in phytochromobilin
synthase activity. This review focuses on how this information
can be used to help und
