How Do Plants Avoid UV Rays?

It is even known that they benefit rather than harm. However, Dangers of UV rays How come the plants that are alive in the open are not harmed?

Research conducted by the scientific worldthe kind that makes us forget what we know on the subject.

Scientific research provides a conclusion about the harms of sunlight.

From Purdue University Timothy Zwier and his team, In an article published in the Journal of the American Chemical Society, they detailed their important research on natural “sunscreens” developed by plants to protect against ultraviolet (UV) rays.

Plants in the process of photosynthesis Using sunlight They produce food, but this process can cause serious damage to plant DNA, especially with harmful rays such as ultraviolet-B (UVB) rays. This damage can stunt plant growth and threaten their health.

Therefore, plants produce special molecules to protect themselves.

They send these molecules to the outer layer of their leaves. At the top of these molecules are sinapate esters. Sinapate esters, By blocking UVB radiation from penetrating into the interior of plants It helps protect plants from these harmful rays.

These molecules Previous biochemical tests on the protective effect of It turns out that sinapate esters act like a sunscreen for plants.

To better understand the protective role of sinapate esters, another comprehensive experiment was conducted.

The molecules were exposed to UVB radiation in a laboratory environment after passing into the gas phase. The results they obtained were, sinapate esters It had the ability to effectively absorb radiation at every wavelength of the UVB spectrum.

These results also show that sinapate esters are very effective in protecting plants from harmful UV rays. The sunscreens of the plants are also sinapate esters.
