IDENTIFICATION OF PHYTOPLASMA FROM MANGOTREES SHOWING SUDDEN DEATH PHENOMENONTHROUGH MOLECULAR TECHNIQUES MUNAWAR RAZA KAZMI, SAIMA IRAM FAROOQ, FAISAL SOHAIL FATEH, SHAHID HAMEED, FAUQIA FAHMEED, MUHAMMAD ASHRAF AND IFTIKHAR AHMED Abstract: Mango (Mangifera indica L.) is susceptible to a number of diseases. One of the important diseases is sudden death phenomenon which is a complex of biotic and abiotic factors. Several fungi have been isolated from mango tree showing sudden death. But some of its symptoms resemble with those caused by Phytoplasma. This study has been made for the detection of phytoplasma from trees showing sudden death. The detection process involved PCR and fluorescent microscopy of samples collected from various locations in Punjab. Out of 90 samples only one sample showed the presence of Phytoplasma. This shows that phytoplasma is not directly involved in the disease development and may be contributing as a predisposing factor.
