Ginkgo tree (ginkgo biloba), famous for its long-lasting healing and healing properties, is considered the oldest tree in the world that appeared 300 million years ago in a time when dinosaurs existed.
Ginkgo trees come from China and have been used in traditional medicine for thousands of years. In the 1990s, many studies have demonstrated that extracts from this herb help improve cognitive abilities in dementia patients. Today, plants are used to treat dementia as well as diseases from depression to circulatory disorders.
When studying plants, scientists recorded the presence of a symbiotic algae .
Scientists discovered this in 2002 when a French pharmacologist at the University of François Rabelais in Tours noted that some transplanted ginkgo cells sometimes turn green.
Deep analyzes have allowed the assertion that living ginkgo cells contain algae 'phantom': these are non-nuclear and strayed cell frames. But when these cells die, the ghosts resurrect and turn into photosynthetic algae.
This strange algae has been discovered in all ginkgo trees observed, regardless of their origin. Symbiotic phenomenon is present in all embryos and reproductive tissues but not in leaves.
Scientists do not explain how this phenomenon works, they argue that the algae depend on ginkgo trees to live and on the contrary provide plants with compounds that are used as medicines.
According to the researchers, this symbiosis has existed for more than 100 million years.
