Abstract:
... The coatomer subunit alpha (COPA) and aquaporin 9 (AQ9) genes from the two-spotted spider mite, Tetranychus urticae, were previously determined to exhibit RNA interference (RNAi)-based lethality when their double-stranded RNAs were systemically delivered via multi-unit chambers (Kwon et al., 2016 [8]). In current study, the hairpin RNAs of the COPA and AQ9 were transiently expressed in soybean pla ...
