ExoRNAi exposes contrasting roles for sugar exudation in host-finding by plant pathogens

Nanovector-mediated exogenous delivery of dsRNA induces silencing of target genes in very young tomato flower buds

“…30 In addition, several studies have shown that roots and young seedlings can absorb both dsRNAs and miRNAs when supplied exogenously. 31,32,69,70 A few reports describe the use of nanomaterials coupled to RNA cargos to silence endogenes. Jiang et al (2014) demonstrated that applying dsRNAs mixed with cationic uorescent nanoparticles to Arabidopsis root caused a signicant reduction in expression of two developmental genes (SHOOT MERISTEMLESS and WHEREWOLF).…”

“…Another successful example of foliar application is that reported byMarcianò et al (2021), where dsRNA targeting a downy mildew susceptibility gene (VviLBDIf7) was applied to fully developed leaves of Vitis vinifera30 .

Transcriptional signatures of invasiveness in Meloidogyne incognita populations from sub-Saharan Africa

“…9, 2019; Moneymaker, in plant growth cabinets at 23°C, with a regular 16 h light, 8 h dark cycle for no more than two generations following field collection. Tomato seedling infection assays were conducted as in Warnock et al (2016), using 200 J2s per seedling, inoculated into an agar slurry containing the tomato seedling.…”
