Bidirectional mRNA transfer between Cuscuta australis and its hosts.

ABSTRACT: The holoparasitic dodder (Cuscuta spp.) is able to transfer mRNA and certain plant pathogens (e.g., viruses and bacteria) from the host plant. "Candidatus Liberibacter asiaticus," the phloem-limited causative agent of citrus Huanglongbing, can be transferred from citrus to periwinkle (Catharanthus roseus) mediated by dodder. However, characterization of mRNA transport between dodder and citrus/periwinkle remains unclear. In this study, we sequenced transcriptomes of dodder and its parasitizing host, sweet orange (Citrus sinensis "Newhall") and periwinkle (Catharanthus roseus), to identify and characterize mRNA transfer between dodder and the host plant during parasitism. The mRNA transfer between dodder and citrus/periwinkle was bidirectional and most of
