Fungus covers fragments of its own cell wall to avoid plant defences

Many fungi can make themselves invisible to the immune system of plants. Scientists from Wageningen University have discovered that the tomato fungus Cladosporium manages this by enclosing chunks of chitin originating from its own cell wall in a protein it specifically produces for this purpose. This prevents the tomato plant from sensing that it is being attacked by the fungus, which has free rein to infect the plant.
