Title

High-Level Accumulation of Exogenous Small RNAs Not Affecting Endogenous Small RNA Biogenesis and Function in Plants

Shen; Wan-xia; Neil; et al. 农业科学学报：英文版 2014

Other claims from this paper (6)

Observation Transgenic Nicotiana benthamiana plants lacked the usual yellowing symptoms of Y-Sat infection.
Intervention effect Y-Sat infection caused no visible phenotype in those plants relative to uninfected plants.
Intervention effect Y-Sat infection did not significantly affect hairpin RNA-derived siRNA accumulation.
Intervention effect Y-Sat infection did not significantly affect miRNA accumulation.
Intervention effect Y-Sat infection did not significantly affect siRNA-directed transgene silencing.
Mechanism The authors infer that abundant exogenous siRNAs do not saturate endogenous RNA silencing machinery.
