characterization and occurrence of squash chlorotic leaf spot virus, a tentative new torradovirus infecting cucurbits in sudan.during a survey conducted in sudan in 2012, a virus with spherical particles was isolated from a squash plant showing chlorotic leaf spots. the virus was transmitted mechanically and by two whitefly species, but not by aphids. rt-pcr with generic torradovirus primers yielded a band of expected size from total rna of a symptomatic plant. next-generation sequencing confirmed that this is tentatively a new torradovirus, for which we propose the name 'squash chlorotic leaf spot virus'. using specifi ...201626935919
