Phytoplasma presence and inoculum sources in carrot fields in Turkey

Abstract

Intensive surveys were conducted in major carrot cultivation areas of Turkey in 2018-2020 and 272 plant samples showing severe symptoms of chlorosis and reddening were collected in Konya and Ankara provinces, After molecular testing and by in silico RFLP analysis on sequences obtained 16SrI-B (‘Candidatus Phytoplasma asteris’) and 16SrVI-A (‘Ca. P. trifolii’) were identified. Furthermore, the inoculum sources of those phytoplasmas in same provinces were investigated. Weeds were collected from surroundings and Daucus carota wild, Medicago sativa, Coniummaculatum and Sinapis arvensis were detected as infected be phytoplasmas in 16SrVI group. In addition, both phytoplasma groups were present in seedlings germinated from seeds of seven carrot cultivars, six were commercially produced and one was a local red carrot cultivar. © 2023, Technology Society of Basic and Applied Sciences.
