Washington [as]: plants produce salicylic acid, known as aspirin, to protect themselves from environmental hazards such as insects, thirst, and heat. A better understanding of this procedure can help plants survive the increase in stress caused by climate change.
New UC Riverside scientists published a mani paper in the Journal of Advanced Sciences which reported how plants regulate salicylic acid production.
The researchers studied the factory model called Arabidopsis, but they hope to apply their understanding of the stress response in this plant cell to many other types of plants, including those planted for food.
We want to be able to use the knowledge gained to increase plant resistance, “said Jin-Zheng Wang, UCR genetic expert and the first writer in a new study.” That will be very important for the supply of food in our world that is increasingly hot and bright. “
Environmental pressure results in the formation of reactive or ROS oxygen species in all living organisms. Without sunscreen on a bright day, human skin produces ros, which causes spots and burns. The high level of ROS in plants is very deadly.
Like many substances, toxins in the amount. At low levels, ROS has an important function in plant cells.
“At a non -deadly level, ROS is like an emergency invitation to act, allowing the production of protective hormones such as salicylic acid,” Wang said. “Ros is a two -edged sword.”
The research team found that heat, sunlight without stopping, or drought caused sugar -making equipment in plant cells to produce early alarm molecules known as MECPP.
In the future, researchers want to learn more about MECPP, which is also produced in organisms such as bacteria and malaria parasites. The accumulation of MECPP in plants triggers salicylic acid production, which in turn starts a chain of protective action in cells.
“This is like a plant that uses painkillers for pain and pain, as we do,” said Wilhelmina van de Ven, UCR biologist and the first study author.
Acid protects plant chloroplasts, which is a place for photosynthesis, a process of using light to convert water and carbon dioxide into sugar for energy.
“Because salicylic acid helps plants withstand pressure to be more common with climate change, able to increase the ability of plants to produce it representing forward steps in challenging the impact of climate change in daily life,” said Katayoon Dehesh, author of senior paper and UCR Professor of leading molecular biochemistry.
“The impact goes beyond our food. Plants clean our air by watering carbon dioxide, offering our shade, and providing habitat for many animals. The benefits of increasing their survival are exponential, “he said. (Ani)
