There’s a new plant fungus among us in the United States and it’s not afraid to cross the Mason-Dixon line. Asian soybean rust, an aggressive fungus of legumes, was first detected in Louisiana in November, and in eight other states since then. Severe infestations can devastate soybean fields.

Just as people clean up after dinner by running food scraps down the garbage disposal, cells get rid of proteins they no longer need by breaking them down with a special chemical pathway.

Ants that tend and harvest gardens of fungus have been closely studied for dozens of years, and are often cited as a model system for symbiosis.
