Abstract

First report of a 'Candidatus Phytoplasma aurantifolia'-related phytoplasma strain associated with yellowing symptoms on pineapple palm in Iran.

Abstract

During the last 3 years, symptoms resembling nutrient deficiency were observed on pineapple palms (Phoenix canariensis) in urban landscapes in Ahvaz in southwestern Iran. The symptoms included leaf yellowing in the lower fronds which began from the leaf tips and extended towards the blade and the rachis. During January 2016, P. canariensis palms were surveyed for phytoplasma. Leaf samples from 3 diseased and one symptomless palm were collected. The causal pathogen was identified as Phytoplasma aurantifolia 16Sr II group, subgroup D based on RFLP and phylogenetic analyses. This is thought to be the first report of Phytoplasma aurantifolia 16Sr II group, subgroup D on Phoenix canariensis in Iran.
