Orchid virus soapbox

Totally agree with you Ray! The phyiscal/social distancing comment really hits the spot here!!! People not only spread virus among themselves, but also responsible for spreading orchid virus! (and spreading other things - other organisms).

For people with virused plants and those who would like to protect their plants from virus, you might want to consider treating your collection with Rhodopsudomonas palastris.

Characterization of Rhodopseudomonas palustris population dynamics on tobacco phyllosphere and induction of plant resistance to Tobacco mosaic virus

Analyses of expres-sions of plant defence-related genes showed that,starting from Phase III, bacterial cells in the Type 3and Type 4 colonies produced unidentified signals toinduce host defence againstTobacco mosaic virusinfection. In addition, we determined the crucial roleof aggregates formation of GJ-22 cell on plant phyllo-sphere in terms of bacterial cell stress tolerance andISR (induced systemic resistance) priming. To ourknowledge, this is thefirst report focused on the col-onization process of a phyllosphere biocontrol agentand gave a clear description on the morphologicalshift of bacterial colony on phyllosphere

Isolation of Rhp-PSP, a member of YER057c/YjgF/UK114 protein family with antiviral properties, from the photosynthetic bacterium Rhodopseudomonas palustris strain JSC-3b

Herein, this protein is designated Rhp-PSP. Rhp-PSP exhibited significant inhibitory activities against tobacco mosaic virus (TMV) in vivo and in vitro. To our knowledge, this represents the first report on the antiviral activity of a protein of the YER057c/YjgF/UK114 family and also the first antiviral protein isolated from R. palustris. Our research provides insight into the potential of photosynthetic bacterial resources in biological control of plant virus diseases and sustainable agriculture.

Yes that is correct, this bacteria produces anti-viral proteins AND induces systemic resistance in plants.
