Identification of phytoplasmas in mango and pomegranate in Guadeloupe

Scattered plants in mango and pomegranate orchards in Guadeloupe showed disease symptoms consisting in branch and leaf dry and small and yellow leaves respectively. Fruits from symptomatic and asymptomatic mango and pomegranate plants were collected and the peel was used for a molecular investigation to verify the possible phytoplasma presence. After PCR/RFLP and sequencing analyses some of the fruits of both species resulted positive for phytoplasmas enclosed in subgroups 16SrI-B and 16SrI-F that in some of the samples were present in mixed infection.
