Some examples I thought about: cyanide, carbon monoxide (although it isn't as toxic to plants as it is to animals), and anything else that disrupts mitochondrial function (though it must be remembered that mitochondria are related to many bacteria)
One suggestion I thought of: what about things that can penetrate the cell membranes of all organisms with a single cell membrane, but might not be able to penetrate the two cell membranes of gram-negative bacteria? Do such substances exist?
PS: I was discussing this issue with NASA Astrobiologist Chris McKay, so any responses would be interesting to him as well.
