A diverse set of miRNAs responsive to begomovirus-associated betasatellite in Nicotiana benthamiana.

ABSTRACT:

Background

Roles of microRNAs (miRNAs) and short interfering RNAs (siRNAs) in biotic stress responses, e.g., viral infection, have been demonstrated in plants by many studies. Tomato yellow leaf curl China virus (TYLCCNV) is a monopartite begomovirus that can systemically infect Solanaceae plants, and induces leaf curling, yellowing and enation symptoms when co-inoculated with a betasatellite (TYLCCNB). The released genome sequence of Nicotiana benthamiana provides an opportunity to identify miRNAs and siRNAs responsive to begomovirus-associated betasatellite in N. benthamiana.

Results

miRNAs were identified in three small RNA libraries generated using RNA isolated from N. benthamiana plants systemically infected with TYLCCNV (Y10A) alone, co-infected with Y10A and its betas
