Comparative small RNA profiles of beet mosaic virus (BtMV), beet mild yellowing virus (BMYV) and beet yellows virus (BYV) infected Nicotiana benthamiana and Beta vulgaris.

ABSTRACT: Plants are constantly challenged by viral pathogens that can limit growth and reduce yield. A key component of the plant innate immunity is RNA silencing, in which viral double-stranded RNA (dsRNA) intermediates are recognised and processed into virus-derived small interfering RNAs (vsiRNAs). These vsiRNAs direct the degradation of viral genomes, thereby restricting infection. Sugar beet (Beta vulgaris subsp. vulgaris) is a crop of major economic importance, where the virus yellows (VY) complex represents a serious threat to production. Here, we profiled and compared vsiRNAs generated during infection of the natural host plant B. vulgaris and the experimental host plant Nicotiana benthamiana with three taxonomically distinct viruses: beet yellows virus (BYV, Closterovirus), beet mild yello
