• A plasma membrane-localized small peptide is involved in rice aluminum tolerance, 2013, Plant J.

Genbank accession number

• OsCDT3 was mainly expressed in the roots and its expression was specifically induced by Al exposure, not by low pH and other metals.
• Expression of OsCDT3 in yeast conferred tolerance to Al, but not to Cd.
• Taken together, our results indicate that OsCDT3 anchoring to the plasma membrane may play a role in stopping entry of Al into the root cells by binding Al, therefore, contributing to high Al tolerance in rice.

• ART1, OsCDT3, A plasma membrane-localized small peptide is involved in rice aluminum tolerance, A transcription factor for Al tolerance, ART1, regulates the expression of at least 30 genes in rice. Here we functionally characterized one of the downstream genes, OsCDT3, which encodes a predicted peptide of only 53 amino acid residues rich in cysteine.
