“…Phytoplasmas are small bacterial plant pathogens that are transmitted by phloem-feeding insects ( 1 , 2 ). Phytoplasmas lack many basic metabolic pathways and thus rely on the host to complete their life cycle and release virulence effectors into plants, causing drastic changes in cell architecture, the defense response, and volatile production ( 3 , 4 , 5 , 6 , 7 ). It is now known that in a variety of plants, phytoplasma infestation has adverse effects on fruits, seeds, and morphology, manifesting as yield loss in wheat, lack of fruit bearing by jujube plants, and decreased quality of paulownia trees ( 8 , 9 , 10 , 11 ).…”
