Infected potato plants showed phytoplasma‐associated symptoms including yellowing, upward leaf rolling, aerial tubers and early senescence. Sugar beet plants showed similar symptoms to those of syndrome ‘basses richesses’ (SBR) disease, including proliferation, yellowing and necrosis of older leaves. The genetic diversity of the phytoplasmas in the symptomatic potato and sugar beet plants was investigated through sequence analysis of 16S rRNA and\n                    \u003cjats:italic\u003estamp\u003c/jats:italic\u003e\n                    ,\n                    \u003cjats:italic\u003evmp1\u003c/jats:italic\u003e\n                    ,\n                    \u003cjats:italic\u003etuf\u003c/jats:italic\u003e\n                    and\n                    \u003cjats:italic\u003esecY\u003c/jats:italic\u003e\n                    genes. The RFLP profiles and sequences of 16S rRNA were identical among all the sugar beet‐positive samples and aligned with subgroup 16SrXII‐P, whereas the potato phytoplasma strains were identified as belonging to subgroup 16SrXII‐A. Sequence analysis of the non‐ribosomal genes showed that the potato strains belonged to the b1 group of the\n                    \u003cjats:italic\u003etuf\u003c/jats:italic\u003e\n                    gene, the V4 and V17 groups of the\n                    \u003cjats:italic\u003evmp1\u003c/jats:italic\u003e\n                    gene and the secY3 and secY4 groups of the\n                    \u003cjats:italic\u003esecY\u003c/jats:italic\u003e\n                    gene.
