Totally 32 weed hosts and crop plants were collected and the DNA was isolated from 32 weeds and crops showing phytoplasma disease symptoms and subjected to PCR amplification with phytoplasma specific primers R16F2n/R16R2. The result shows that R16F2n/R16R2 primer amplified 1250bp product in 19 weeds and other crop species. The notable contribution in the present study was identification of six new hosts for phytoplasma for the first time in the Andhra Pradesh. They are Cleome gynendra, Solanum duclamara, Portulaca oleracea, Aerva lanata, Celosia argentea and Pergularia daemia in Andhra Pradesh. | Molecular characterization of phytoplasma associated with crops weeds and forest trees in Andhra Pradesh India
