5-Azacytidine Induced Protein 1 (AZI1)

Mitogen-activated protein kinases and their targets have been in the limelight of plant stress research. Signaling pathways mediating the responses to multiple stresses deserve particular attention.AZI1, a member of the lipid transfer protein family, to play a role in MPK3-mediated responses to salt stress in Arabidopsis thaliana. MPK3 controls AZI1 at the transcriptional and posttranslational level. The AZI1 protein has several properties that make it very attractive for genetic engineering. A model of multi-level control of AZI1 by MPK3 is proposed, and strategies toward optimizing AZI1 protein properties are briefly discussed.
