Plants are boring. They just sit on photo intelligence, and the animals do everything. right? So too. Look at the relationship between ants and plant-plants that are specially designed by the ants, such as juicy nectar for insects for a meal and a restless thorn to receive shelter. In return, plants use ants seed and act as a protection. New research Works of the National Academy of Sciences The 1,700 species of antisys genetics and 10,000 plants are generated, and researchers have discovered that the long history of anti-plant and plant equality began with anti-state attributes against plants and plants.
"My main interest is to learn how the interaction between the organisms developed and how these relationships impact their evolutionary history when the ants started using the plants and when the plants began to use ants?" Says Ms. Nelsen, a researcher and lead author of the field museum PNAS Learning.
"There are plants of different structures that are specific to antioxidants," explains Nelsen, who studied with his fellow field musician researchers and co-authors with Rick Rice and Cory Morro. "Some plants have voiced the symptoms that make ants in order to protect them from other insects and even mammals that inflammation that the ordeals live inside or excessive nectar for leaf or sheets to eat, take nectar and run, but some will stick around and attack nothing Who is trying to hurt you factory ", explains Nelsen. Other plants will receive ants in order to help their seed around them digging into rich food packages that are called seed. "Ants will choose the seeds and carry it, eat food and ignore the seeds, often in the richest area in the rural area where it grows better, and because it is far off from his parent to stop the resource."
But scientists were not sure how evolutionary relationships started between ants and plants. If evolution is a weapon race, including the development of ways to win neighbors, then scientists knew whether the first shot of the plant or ants. "It was a chicken and egg question that started with ants developing developments to benefit from plants or plant growth that began with ants," says Rae, a vegetable curator in the field museum.
The development of ants and plants together goes into dinosaurs time and it is not easy to know how the debris creates. "The plants are very small fossils of these structures and they do not go very far and are even fossil fossils, but they usually do not show these behaviors – we do not necessarily see them in a seed-containing plant," Nalsen says.
So, in order to determine the earliest evolutionary history of early plant interaction, Nelsen and his colleagues found large quantities of DNA data and ecological databases. "In our study we learn from these behavioral and physical properties of ants and plant family trees to determine when the ants wanted to eat and plant life and when the plants could develop the ability to produce structures," explains Meru, field curator Ants.
The history of plants' anti-planting properties and ants "The use of plants on these family trees – the process called the state reconstruction of the ancestors, was able to determine when the plant protection and seed distribution began with the ant, and as if the ants were not based on the majority of the plants most directly dependent on the plants And ants because the plants did not develop these specialized structures, relying on their food and shelter.
"Some ant does not use most plants directly, and others rely on food, seeds and shrubs. We have found that we are investing fully with the consumption of plants, the ant was initially started with tuberculosis, then mixed plants in the diet and then they started to ant, but this step was a step forward Plant increased d mokidebulebata intuitive, he was still surprised, "- says nelseni.
For years, the mutual beneficial relationship between ants and plants was evolutionary, with groups of antibodies or dirt groups in plants that are not better. "We do not see a part of the fetus's fetus that contains plant and habitats that are diversifying or faster than plant foods and habitats, rather than those parts of the trees that do not have these relationships," says Nelsen. "This research is important because it provides a sense of how this broad and complex interaction has developed."
