First report of `Candidatus Phytoplasma aurantifolia' associated with severe stunting and necrosis on the invasive weed Pelargonium capitatum in Western Australia
Plant Disease 94 (10), 1264-1264
Abstract: During 2008, invasive Pelargonium capitatum (rose pelargonium) plants growing in Western Australia were observed with symptoms of small misshapen leaves in clumps that were often chlorotic or pink, shortened internodes, and exhibited phylloidy typical of infection by a phytoplasma. Patches of the weed were stunted and dying. DNA was extracted from symptomatic plants and analyzed by PCR using phytoplasma specific primers. Subsequent 16S rDNA examination showed the presence in the plants of a phytoplasma with high sequence identity between isolates (~99%) and with the `Candidatus Phytoplasma aurantifolia' (16SrII) group of phytoplasmas.
