First report of a 'Candidatus phytoplasma aurantifolia' strain associated with virescence, floral proliferation, and dwarf symptoms on Indigofera suffruticosa in Taiwan.
In February 2016, Indigofera suffruticosa plants showing virescence, floral proliferation and dwarf symptoms were collected from commercial fields of Mingjian Township, Nantou County, Taiwan. Two each of symptomatic and asymptomatic samples were collected from the field for further study. The causal pathogen was isolated and identified as Phytoplasma aurantifolia based on various molecular analyses. This is thought to be the first report of a 16SrII-V subgroup phytoplasma causing virescence, floral proliferation, and dwarf symptoms on I. suffruticosa in Taiwan.
