WebCanonical RNAi, one of the so-called RNA-silencing mechanisms, is defined as sequence-specific RNA degradation induced by long double-stranded RNA (dsRNA). RNAi occurs in four basic steps: (i) processing of long dsRNA by RNase III Dicer into small interfering RNA (siRNA) duplexes, (ii) loading of one of the siRNA strands on an Argonaute protein … Web12 ore fa · 5.2 纳米载体对dsRNA的保护. 由于dsRNA被植物吸收不是一个瞬时的过程，有延迟效应，喷洒型RNA农药在田间的应用效率与 dsRNA在环境中的稳定性密切相关。高效的RNAi依赖于充足的dsRNA，但实际应用中诸多因素会影响 dsRNA在植物表面的积累。 stihl br550 backpack blower manual
