Rathayibacter iranicus (Ri), originally reported in Iran in 1961 (Sharif, 1961), has not been reported outside Iran and only one strain is known to exist. Like R. tritici (Rt), Ri causes a gumming disease of wheat in association with the nematode Anguina tritici (Paruthi et al., 1989). During 2003, a survey of wheat seed for Rathayibacter species (RS) in Turkey using samples from 799 farmers in six provinces in Central Anatolia was conducted. Identification of the three strains as Ri was further supported by 16s rDNA sequence similarities to Ri and Rt of 100%and 99.3%, respectively (GenBank Accession Nos. FJ595101 - Ri, ICPB 70005 and FJ595102 – Rt, ICPB 70004). Identification asRi was confirmed by AFLP analysis (EcoRI+0 and MseI+C) showing a pattern of 90% similarity to Ri but only 46% to Rt. This is the first report of Ri outside of Iran.
