Nitrogen-Fixing Rahnella Bacteria Promotes the Growth of Wheat

Researchers from the Eternal University and partners have discovered that the Rahnella bacteria have nitrogen-fixing capabilities, which can boost the growth of wheat.

Certain bacteria can convert the nitrogen gas from the air into forms that plants can use. However, researchers must first identify which type of bacteria have nitrogen-fixing capabilities and to which crops they can be applied.

Scientists isolated endophytic bacteria from cereal crops in India and screened them for nitrogen fixation. The eight bacterial isolates that exhibited nitrogenase activity were also tested for other growth-promoting traits.

Video: New research chair appointed to accelerate crop variety development

Funded by Sask Wheat, the Wheat Pre-Breeding Chair position was established to enhance cereal research breeding and training activities in the USask Crop Development Centre (CDC) by accelerating variety development through applied genomics and pre-breeding strategies.

“As the research chair, Dr. Valentyna Klymiuk will design and deploy leading-edge strategies and technologies to assess genetic diversity for delivery into new crop varieties that will benefit Saskatchewan producers and the agricultural industry,” said Dr. Angela Bedard-Haughn (PhD), dean of the College of Agriculture and Bioresources at USask. “We are grateful to Sask Wheat for investing in USask research as we work to develop the innovative products that strengthen global food security.”

With a primary focus on wheat, Klymiuk’s research will connect discovery research, gene bank exploration, genomics, and breeding to translate gene discovery into improved varieties for Saskatchewan’s growing conditions.
