Characterization of differential expression and leader intron function of Arabidopsis atTOC159 homologous genes by transgenic plants.

ABSTRACT:

Background

Accurate import of thousands of nuclear-encoded proteins is an important step in plastid biogenesis. However, the import machinery of cytosolic precursor proteins to plastids relies on the Toc and Tic (translocons on the outer envelope and inner envelope membrane of chloroplasts) complexes. Toc159 protein was identified in pea (Pisum sativum) as a major receptor for the precursor proteins. In Arabidopsis thaliana, four psToc159 homologs are identified, termed atToc159, atToc132, atToc120 and atToc90. The expression of these protein-encoding genes has to be properly regulated, because their gene products must be correctly integrated to appropriate apparatus to perform their functions.
