This suggests that symptom-mitigating satRNAs better maintain the virus's epidemiological potential, which may limit the environmental persistence of variants that strongly exacerbate pathogenesis.

The main driving force behind this work was Basia Wrzesińska-Krupa.

•The efficiency of virus acquisition depended on the host and the virus-satRNA combination: exacerbating satRNAs generally reduced virus acquisition on the insect's stylet.
•Transmission efficiency was significantly reduced for symptom-exacerbating satRNA variants, particularly in S. lycopersicum.

these novel cornflower partitiviruses appear regardless of resistance status. However, there are some differences in the bacterial microbiome. Several genera (e.g. Rothia) are more abundant in resistant plants
This is the first insight into #microbiome and #virome of herbicide-resistant cornflower
