Researchers use synchrotron light to ‘peel the glass’ on cell walls to help plants withstand drought and disease.

“We know there’s a lot of drought on campuses, and people’s lives are on the line,” said Ariana Forand, a Master’s student in the College of Agriculture and Bioresources at the University of Saskatchewan (USask). “It’s amazing to have changes that allow plants to avoid so many problems.”

Forand led a project that explored how calcium and boron work effectively in strengthening the walls of plants, helping to reduce the dehydration that comes with dehydration. dryness and drought and increased resistance to pathogens.

As it turns out, the right plant to test the concept is glass.

The company assembles glass samples and collects data at Advanced Photon Source (APS) in Illinois, thanks to the in -house partnership with the Canadian Light Source (CLS) at the University of Saskatchewan.

“This project really builds on the work of a former Sask teacher, Jun Liu, who did a really fun job,” Forand said, “and we see the dryness and the cold, plants disappear in similar ways. “

Onions are a good plant to use “because you can peel a single layer of cells and see changes in the cell wall,” a plant -based key to prevent stressors. unlike.

A special feature of this study was that the results were published in a journal PlantsIt is the focus of many stressors at the same time – dehydration in Welsh onions and cooking glasses, and pathogen resistance in Arabidopsis, a small flower in Africa.

After adding calcium mixed with water to the glass grown in the greenhouse, Forand used synchrotron X-ray microscopy to confirm the removal of the plants. in calcium but it is found in the courtyard.

Further experiments with dry conditions showed reduced water loss in the plants maintained. Similarly, boron has been shown to bind with pectin in the cell walls of Arabidopsis, strengthening its resistance to infectious diseases.

“We’re looking for ways to strengthen cell walls,” Forand said. Supplementation of calcium and boron reduces the risk of water loss and diseases open the door to seek a similar effect in other plants.

Dr. Karen Tanino, Sask’s plant scientist and director of Forand, says that each year, “it can be more important than any other – you can’t really predict the future. the future. changes in weight from year to year. “

Forand and Tanino believe that expanding their research will provide opportunities to strengthen the fight against water loss and diseases in both the crop and horticulture industry.

Tanino, the first Sask plant scientist who used synchrotron technologies at CLS in a project that looked at the resistance to frost in – coincidentally – glass, said that while binding the walls of plants that fight against all sorts of problems are not a money bubble. a front line of defense. ”

Research on the fence shows that it can easily and consistently protect plants
