Analysis of gene expression from fbn5-1 T-DNA insertion mutant of Arabidopsis

ABSTRACT: We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes in fbn5-1 T-DNA insertion Arabidopsis mutant. Fibrillins are lipid-associated proteins in plastids and are ubiquitous in plants. Fibrillins are known to accumulate and sequester carotenoids in chromoplasts during the development of flowers and fruits; however, little is known about the function of fibrillins in leaf tissues. Here we identified a novel protein fibrillin5 (FBN5) that is essential for plastoquinone-9 (PQ-9) biosynthesis in Arabidopsis thaliana. We showed that homozygous fbn5-1 plants were seedling-lethal, and XVE:FBN5-B transgenic plants expressing low levels of FBN5-B showed a lower growth rate and were smaller than wild-type.
