Compositions and methods for targeting polypeptides to plastids are
provided. Compositions comprise plastid transit peptides as well as
nucleotide sequences encoding such transit peptides and variants thereof.
Compositions further comprise DNA constructs comprising a nucleotide
sequence encoding the plastid transit peptide operably linked to a
nucleotide sequence encoding a polypeptide of interest. These DNA
constructs find use in expression and targeting of the polypeptide of
interest to a plastid. Compositions also comprise expression cassettes,
vectors, transformed plants, transformed plant cells, and stably
transformed plant seeds wherein a polypeptide of interest is targeted to
a plastid by the plastid transit peptide of the invention.
