For more than three billion years, cyanobacteria, the blue-green algae seen in some lakes, has been converting sunlight to chemical energy through photosynthesis.
Most of this process involves visible light humans can see. But Brock University Assistant Professor of Chemistry Divya Kaur Matta is curious about a particular species that uses an almost invisible portion of the colour spectrum to convert light and store energy — knowledge that could have powerful implications for agriculture.
Matta was among 18 Brock researchers awarded funding from the Natural Sciences and Engineering Research Council of Canada (NSERC), announced Friday, June 14.
The University received more than $3 million from the 2024 round of Discovery Research Programs grants.
Included was the work of Alonso Zavafer, whose interest also lies in light and crops, specifically colours given off by plants during photosynthesis.
The Assistant Professor of Biological Sciences and Engineering is developing tools that use the colour of plants as a way of continually monitoring their health, nutrition and metabolism, another potential boon for the agriculture industry.
“As these funding successes show, Brock researchers are continuing to expand their strengths in agricultural research,” says Acting Vice-President, Research Michelle McGinn. “We are grateful for NSERC’s support within this field and across the broad range of other topics funded this year.”
Matta’s project involves studying a particular marine cyanobacterium called Acaryochloris marina (A. marina). This species contains pigment molecules called chlorophyll d that allows it to draw energy from far-red light, which is on the extreme red end of the visible colour spectrum. It is one step away from infrared light that is invisible to the human eye.
Matta’s research group, the Computational Biophysics Laboratory, is aiming to better understand how A. marina and other species are able to gather and store energy under very low light conditions. She says such information could help boost global agriculture and food security.
“This remarkable ability to adapt suggests that it could be used to engineer crops that thrive in shaded conditions and may even lead to innovations in sustainable energy,” Matta says.
Increasing food security is also the aim of Zavafer’s research, which is in the field of ‘biophotonics.’
A photon, the smallest particle of light, emits visible and near-visible light. Biophotonics includes studies of photons in biological systems to see if cells and tissues are healthy, playing a major role in medical imaging and therapeutic procedures.
