Intracellular localization and delivery of plasmid DNA by biodegradable microsphere-mediated femtosecond laser optoporation.

abstract：:Basidiomycetes, that is, mushroom-type fungi, are known to produce pigments in response to environmental impacts. As antioxidants with a high level of unsaturation, these compounds can neutralize highly oxidative species. In the event of close contact with other microbes, the enzymatically controlled pigment productio...
