Although protein secretion was previously believed to be solely via ER/Golgi pathways, Golgi-independent secretion has now been described in both animals and plants. Secretion of the mannitol catabolic enzyme mannitol dehydrogenase (MTD) in response to the endogenous pathogen response signal salicylic acid (SA) was one of the first reports of unconventional protein secretion in plants. To begin assessing potential secretion-associated MTD protein interactors, we present here high-quality databases describing changes in MTD-interacting proteins following SA treatment of Arabidopsis thaliana cells expressing MTD.
