Recently I’ve been thinking a lot about how non-axenically-cultured plants are commonly imported/exported, and how this means their endophytes inevitably get imported/exported too. And also how asymptomatic commensal or mutualist endophytes in one species can be pathogenic in another. And also also how lots of nonnative endophytes that are asymptomatic in every single one of their hosts may nevertheless be subtly altering the ecosystem in who knows what ways. And also also also how global biosecurity is very poor, because of the vast number of angiosperm, cryptogam, and fungal weeds I see in nursery flowerpots for sale (not to mention the jillions of mites and springtails).
And perhaps most importantly of all, how almost no one is publishing very much on this issue simply because many endophytes suffer a lot from Uncharismatic Microflora bias.
Is there even any reasonably possible way to import/export non-axenic plants outside their native ranges without risking the unleashment of some invasive fungus that no one will pay attention to (because it doesn’t damage crops and its harmful impact in alien ecosystems is non-obvious)?
