Abstract

Recently, symptoms of leaf yellowing and curling, little leaf, severe stunting and phyllody were observed in tomato fields in the Meerut district of western Uttar Pradesh, India, with an incidence of 5-8%. To investigate whether or not a phytoplasma is associated with the disease, 8 tomatoes with indicative symptoms and 8 without symptoms were collected from 2 fields in Samaspur-Surani village, Meerut. The causal pathogen was identified as Phytoplasma aurantifolia based on PCR and RFLP analyses. This is thought to be first report of a 16SrII-D phytoplasma (P. aurantifolia) on tomato in India.
