    Title: Aphid salivary protein Mp1 facilitates infestation by binding phloem protein 2-A1 in Arabidopsis.
  2. These results suggest that the AtPP2-A1 molecular chaperone protein plays a critical role in the Arabidopsis defense system against diverse external stresses including fungal pathogenic attack and heat shock.

  3. A repression of phloem feeding was induced by HrpNEa in wild-type (WT) Arabidopsis but not in atpp2-a1/E/142, the plant mutant that had a defect in the AtPP2-A1 gene, the most HrpNEa-responsive of 30 AtPP2 genes.

  4. These results indicate the presence in PP2-A1 of several carbohydrate-binding sites, with potentially different functions in the trafficking of endogenous proteins or in interactions with phloem-feeding insects.[PP2-A1]
