More than 50 years ago on the shores of a rock swimming pool, American scientist Robert Paine discovered that taking a species from an ecosystem could dramatically change its appearance and behavior. his work. He saw the role of starfish as a high rock in their habitat and their position as high -ranking predators to maintain the coexistence of different species in the universe. Rock center.

Plant protection genes were tested with a simple ecosystem in the lab

A team of scientists and geneticists at the University of Zurich (UZH) and the University of California, Davis has now found that mutations in a single gene can significantly change nature and behavior. function of an ecosystem. The article, published at Science, It is said that the gene not only influences the information that determines the body’s shape, but can also promote the continued interaction of traits within an ecosystem. The discovery of Jordi Bascompte, a physician in the UZH Department of Evolutionary Biology and Environmental Studies, and his team was made using an experimental ecosystem in the room with a predator (a parasitic wasp), two herbivores (aphids), and the plant Arabidopsis thaliana. . —A genetic model.

The ‘Keystone gene’ can prevent ecological collapse

The researchers tested the effect of three plant genes that control the plant’s natural immune system in chemical barriers to herbivores. They found that herbivores and predators were more viable in their experimental communities on plants by modifying a gene called AOP2. “Not only did this natural mutation of AOP2 affect the chemistry of the plant, but it also increased plant growth, which in turn helped herbivores and predator coexist, thus preventing and in ecological collapse, “explains UZH scientist and lead author Matt Barbour. Like some key rocks such as starfish, AOP2 acts as a “key rock gene” that is critical to the survival of the experimental ecosystem.

Impacts on current health care

The discovery of a core rock chain will have implications for how biology is managed in a changing world. Importantly, knowledge from genetics and ecosystems should be included when predicting the effects of genetic modification on the maintenance of biodiversity at scale. Humans with different species of species or genetically modified organisms can be integrated into current populations to develop diverse and stable ecosystems. However, even a small amount of change can have unintended consequences for ecosystems if not studied first. “We’re just beginning to understand the effects of genetic modification on the relationship and coexistence of species.,” Barbour said.
