French scientists have successfully grown a white truffle, one of the most expensive mushrooms, artificially for the first time by planting mycelium in over 1,000 young oak seedlings in a greenhouse. This breakthrough, after 20 years of research, marks a significant achievement in the agricultural sector. However, the truffles are not yet bearing fruit and the yield remains uncertain. The process requires specific soil conditions and a minimum temperature of 20 degrees Celsius.
