Mercurialis ambigua and Solanum luteum: two newly discovered natural hosts of tomato yellow leaf curl geminiviruses
European Journal of Plant Pathology 106 (4), 391-394
Abstract: The yellow leaf curl disease of tomato is caused by a complex of virus species, two of which, tomato yellow leaf curl virus (TYLCV)-Sar and TYLCV-Is, are involved in epidemics of southern Spain. Plants of Mercurialis ambigua and Solanum luteum showing abnormal upward leaf curling and leaf distortion collected in the vicinity of tomato crops were found to be naturally infected with TYLCV-Is and TYLCV-Sar, respectively. These weed species, as well as Datura stramonium and S. nigrum, which had also been found to be naturally infected by TYLCVs in the same region in previous studies, were tested for susceptibility to TYLCV-Sar or TYLCV-Is by Agrobacterium tumefaciens-mediated and by Bemisia tabaci inoculation. Results indicated that both TYLCV-Sar and TYLCV-Is were able to infect D. stramonium and M. ambigua, whereas only TYLCV-Sar infected S. nigrum and S. luteum. Implications for the epidemiology of TYLCV are discussed. This is the first report of M.ambigua and S. luteum as hosts of TYLCV.
