| Outline of Final Research Achievements |
Arabidopsis AtPep1, an endogenous peptide elicitor, is thought to be somehow released from infected cells and induce defense responses. To examine how Atpep1 is released from cells, we generated AtPep1 overexpression lines and tried to detect AtPep1 by antibody. AtPep1 overexpression lines showed shifted balance in plant hormones even under no stress growth conditions. Therefore it is possible that AtPep1 is release actively from living cells. We also grew AtPep1-overexpression lines under various stress conditions to see clear evidence for active release, and found that these lines were more tolerate to high salinity environment.
