    • Abstract

       

      Intracellular pathogenesis-related gene (IPR) from tomato was cloned from a salicylic acid (SA) induced cDNA library and was designated asTSI-1 (tomato stress induced-1). The deduced amino acid sequence ofTSI-1 codes for a 178 amino acid polypeptide of molecular weight 20.4 kDa.TSI-1 is highly homologous to the potatoSTH-2 andSTH-21 IPR and tree pollen allergens which cause type I allergic reactions in humans.TSI-1 lacks a signal peptide like other IPR members. It is organized as a multigene family and is inducible by SA andFusarium oxysporum infection.
