Integrated Analysis of the miRNAome and Transcriptome Reveals miRNA-mRNA Regulatory Networks in Catharanthus roseus Through Cuscuta campestris-Mediated Infection With "Candidatus Liberibacter asiaticus".

ABSTRACT: Citrus Huanglongbing (HLB) is the most devastating disease of citrus caused by the Gram-negative phloem-limited bacterium "Candidatus Liberibacter asiaticus" (CLas). It can be transmitted by the Asian citrus psyllid "Diaphorina citri," by grafting, and by the holoparasitic dodder. In this study, the non-natural host periwinkle (Catharanthus roseus) was infected via dodder (Cuscuta campestris) from CLas-infected citrus plants, and the asymptomatic leaves (AS) were subjected to transcriptomic and small-RNA profiling. The results were analyzed together with a transcriptome dataset from the NCBI repository that included leaves for which symptoms had just occurred (S) and yellowing leaves (Y). There were 3,675 differentially expressed genes (DEGs) identified in AS, a
