General Information

General Information	Comment	Organism
malfunction	both the albino and dwarf phenotypes of the pds3 mutant result from functional disruption of the PDS3 gene. Chloroplast development is arrested at the proplastid stage in the pds3 mutant. Further analysis shows that a high level of phytoene is accumulated in the pds3 mutant. Disrupting PDS3 gene results in gene expression changes involved in at least 20 metabolic pathways, including the inhibition of many genes in carotenoid, chlorophyll, and GA biosynthesis pathways. The accumulated phytoene in the pds3 mutant might play an important role in certain negative feedbacks to affect gene expression of diverse cellular pathways	Arabidopsis thaliana
