American scientists from the Massachusetts Institute of Technology (MIT) say they have successfully developed a way to grow wood structure in a lab from ceils*taken from the leaves of a flowering plant—zinnia. The method may create different wood products indoors in a single process.

Luis Fernando, the lead researcher on the project of MIT, told MT News the process has a long way to go But if it can be perfected, it could be simpler and faster to produce wood products. For example, it can take many years to make a wooden table. First, a tree has to grow. Then, it must be cut down, transported, processed, etc. Luis said lab-grown wood would combine all those steps intone. "If you want a table, then you should just grow a table," he said.

The experiment was carried out indoors. It requires buildings, heat, or artificial light instead of natural sunlight. During the process, the researchers mixed up two plant hormones*that helped the cells grow a thick, strong wood-like structure. With further development, the researchers said they could use the same process to grow wood in specific shapes, such as a table or chair.

Ashley Beckwith, a doctoral student at MIT, told MIT News the experiment showed that growing plant structures in a lab could be a more efficient*way to use land and resources. Such a lab-based farming method, which is free from the dependence on weather and seasons as traditional farming does, is more likely to improve yields. The process could also reduce plant waste so that it could greatly cut the cost of production. Moreover, if wood products could be produced in a lab, there would be more land to grow crops and the damage to the world's forests would be reduced.

However, Luis Fernando said his team still need to improve the method, especially to learn how to better control the final structure that is produced. And the researchers also want to carry out new experiments to see whether the same results can be reached with other kinds of plants.
