Urapan (Fraxinus udhei) dieback, a new disease associated with a phytoplasma in Colombia
Plant Pathology 53 (4), 520-520
Abstract: A dieback disease of Urapan trees is described from Colombia. The symptoms include yellowing of leaves, little leaves and unusual patterns of regrowth of crowns and less commonly on trunks of mature trees, which often give the foliage a tufted appearance. A phytoplasma was found in affected trees. Part of the 16S rDNA was sequenced and was found to share 94% homology with Ash Yellows (AshY3) gene 16sRNA.
