The secret of the plant cells was decided to unravel the biologists. The University of California experts believe that this result can lead to increased yields of different crops. And the secret of the cells lies in the fact that when they are not divided into their own correct copies, their growth slows down and stops. Today, the scientists first came to the conclusion that the TANGLED1 protein can lead to the exact division of the plant cells.
Each plant cell contains certain microtubular structures inside. They act as transport routes via that the proteins and organic nutrients travel. These structures are also important for the DNA separation after duplication to obtain the second cell from the first.
Carolyn Rasmussen, an assistant professor of plant cell biology at the University of California at Riveride, says that there is no living organism, including the plants, that can live without this microtubular structure. Its functions are controlled by the TANGLED1 protein. It ties microtubules together, acting like a glue.
The scientists conducted an experiment in the laboratory by placing microtubules and protein in one tube. It turned out that proteins can bind them only at a certain angle: 40 degrees. This is the only vegetable protein that acts according to that scheme.
This is probably crucial in determining the daughter cell. Animal cells usually attach to the surface, continuing to divide. If after the division the cell is not attached to the surface, it means the onset of the formation of a cancerous tumor.
Now that scientists have seen how the protein works, they intend to study its genes in order to learn how to control the process of cell division. This process can be controlled, and if you understand the mechanism of the gene control, you can achieve an increase in the yield of various crops.
