UA scientists learning how plants communicate with their environment

A machine with sharp gears, a long rod of metal sounds like a kitchen blender. But this machine is far from your kitchen appliance.

“This is a tissue homogenizer,” said Jesse Woodson, an associate
professor at the University of Arizona’s School of Plant Sciences.

The University of Arizona is the best place to learn about how plants communicate with one another. The ultimate
Our goal is to engineer plants so that they can survive in a warmer environment.

“We want to be able to establish communication with plants,” Woodson
said. “And in order to do that, we need to know how plants are thinking
about their environment and be able to sense their environment.”

Woodson and his student team are part a larger network that includes researchers. The National Science FoundationIn October, a $25 million grant

plants for a future environment that’s likely to be warmer and drier.

Their research is part of the foundation’s new Center for Research on
Programmable Plant Systems, or CROPPS. The scientists are currently working on

Despite not being audible, plants communicate with each other all the time.

“They might be sending those signals internally within the body of
the plant to help the shoots understand what’s going on in the roots,”
Rebecca Mosher is the University of Arizona’s lead investigator in the CROPPS research project. “They might be sending those signals to microbes in the soil
To recruit those microbes. So we want to understand these.
Signals so that we may tap into them and communicate
plants ourselves.”

These internal signals are similar in nature to the signals that our brains send.
When we are under stress or in dire need of nutrition. Woodson stated,
Plants lack the same response as humans. Plants can’t move.

“If we want to get away from something, we can run away. But a plant
has to stay there and they have to deal with whatever happens,” he said.
“So if it’s a hot day, it’s a dry day, there’s too much sun, if there’s
If the plant doesn’t get enough sunlight, it must take steps to compensate.

Experimenting to Understand

“We might give it very high light or lots of heat, a whole variety of

So biotic stress. And then we’ll collect that tissue and take it into

Inside the lab, the team extracts cells using different methods –

team, said that the chloroplasts can reveal a lot more about how plants react to certain conditions

going to be turning more and more like Arizona as the planet heats up,”
Woodson said.

According to the Weather Underground, last year was the sixth-warmest ever recorded. The National Oceanic and Atmospheric Association.
And 2020 was even hotter – it was the second warmest year on record.
December 2021 was the fifth warmest December in 142.
