摘要

Recent completion of the Arabidopsis genome revealed that this organism has ten times more peptide transporters than any other sequenced organism (prokaryote or eukaryote). These transporters are found in three protein families: the ABC-type transporters; the di- and tripeptide transporters; and the newly described tetra- and pentapeptide oligopetide transporters. The abundance of these transporters suggests that they play diverse and important roles in plant growth and development. Possible substrates for these transporters include glutathione, gamma-glutamyl peptides, hormone-amino acid conjugates, phytosulfokine, peptide-like compounds and peptide phytotoxins. However, the exact role of peptide transport in plants is still undefined.
