First report of 'Candidatus Phytoplasma australasia'-related strains associated with disease of Jasminum multiflorum in India.
Jasminum multiflorum cv. Star Jasmine (Oleaceae) is an important ornamental shrub native to South-East Asia. It is cultivated across the tropics for its ornamental value, in particular its fragrant, beautiful white flowers. During February 2020, symptoms of leaf yellowing and the premature decline of inflorescences were observed on 6.5% of plants grown in home gardens in the Uttara Kannada district of Karnataka, India. The causal pathogen was isolated and identified as Phytoplasma australasia based on various molecular analyses. This is thought to be the first report of the association of P. australasia affecting J. multiflorum in India.
