Scientists have discovered a fig tree fungus that only works with another. This has been reported by Nagoya University.
The number of fig trees is declining in many countries. It is traditionally believed that one of the causes is a fungus. Ceratocystis ficicolatransmitted by insect Euwallacea interjectus. Now Japanese scientists have isolated another fungus, fusarium kuroshiumharmless on its own but destroying if it grows with fig trees C. ficicola.
The authors infected fig seedlings with various combinations of fungi collected from the beetle to determine whether the fungi were associated with damage to fig trees. E. to intervene. They planted a fungus on the trees of the control group. Neocosmospora metavoransIt is found in a wide variety of host plants, including avocados and coffee. Some seedlings got only one of the three mushrooms and one group got a combination F. kuroshium and C. ficicola.
As expected, the seedlings became infected C. ficicolawilted, the other two groups only infected N. metavorans or simply F. kuroshium, – no, this indicates that these two fungi in themselves do not harm fig trees. However, in the combined group F. kuroshium and C. ficicola The seedlings dried out less than two weeks after infection and had a large area of dead wood.
From this, scientists came to the following conclusion: F. kuroshium and C. ficicola creates a symbiosis harmful to fig trees.
