Sweet orange (Citrus sinensis) and Orlando tangelo (C. paradisi × C. reticulata) trees showing witches'-broom symptoms were observed during 2018 in southern Kerman province, Iran. Detection of phytoplasmas in the symptomatic trees was confirmed by nested PCR assays using the phytoplasma specific primers. Sequence analysis indicated that the phytoplasmas associated with the witches'-broom affected trees belong to the 16SrII-C subgroup phytoplasma. This is the first report of a 16SrII-C phytoplasma associated with witches'-broom symptoms of Sweet orange and Orlando tangelo trees in the world.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
