Boosting Vitamin C in Plants Can Help Reduce Smog Damage

UC Riverside (UCR) research shows boosting plant vitamin C levels can minimize ozone’s damaging effects RIVERSIDE, Calif. – www.ucr.edu –

The harmful effects of smog on people and animals – the stinging eyes and decreased lung capacity – are the stuff of well-researched fact. Now, the body of knowledge about air pollution’s effects on plants has grown with University of California, Riverside Biochemistry Professor Daniel Gallie’s discovery of the importance of vitamin C in helping plants defend themselves against the ravages of ozone – smog’s particularly nasty component.

By manipulating dehydroascorbate reductase (DHAR), a naturally occurring enzyme that recycles vitamin C, to increase the level of the vitamin in leaves, Gallie has been able to reduce the harmful effects of ozone on plants, apparent as brown spots, stunted size, and lowered crop yields. He and Assistant Research Biochemist Dr. Zhong Chen published their findings in a recent paper titled Increasing Tolerance to Ozone by Elevating Foliar Ascorbic Acid Confers Greater Protection Against Ozone Than Increasing Avoidance, in the journal “Plant Physiology.”

Gallie’s previous research found that plants react to smog much like they react to drought, by closing pores (called stomata) present in their leaves. The closed pores protect plants from losing water and taking in ozone, but also prevent the production of sugars through photosynthesis, which are needed for the plant to grow. “It’s clearly not an effective strategy to protect plants from the effects of long-term exposure to smog,” Gallie said. Plants, he said, have two options to defend themselves from ozone. They can prevent ozone from entering the leaf by closing their stomata, or use the antioxidant qualities of vitamin C to detoxify the ozone that enters through open stomata and also protect the photosynthetic machinery in the leaf.

Studying acute and chronic ozone exposures, Gallie and Chen looked at which plants fared better, those with lower levels of vitamin C that closed their pores or those with higher levels of vitamin C, open pores, and higher levels of photosynthetic activity. Those with the higher levels of vitamin C fared better in the long run, in both instances, despite the fact that more ozone entered through the open pores of the leaf, Gallie said. Gallie and Chen’s findings offer a clear direction for a strategy toward developing plants that will be able to grow and thrive in high-ozone environments such as cities and suburban areas. “Because we’re seeing, especially in this country, the encroachment of urban areas into farm lands, we’re seeing an increased impact on agriculture.

Moreover, ornamental plants used for urban and suburban landscaping are heavily affected by exposure to smog,” said Gallie. The next step in Gallie’s research will focus on the apparent correlation between a plant’s increased vitamin C levels and increased photosynthetic activity. “There seems to be multiple benefits of increasing the level of vitamin C in plants, including improving their tolerance to smog, improving photosynthesis, and improving their nutritional quality but more research is clearly needed,” he said. The key question, at least in the near term, is to determine whether increased vitamin C and photosynthesis will result in greater crop yields, he added.

The University of California, Riverside is a major research institution and a national center for the humanities. Key areas of research include nanotechnology, genomics, environmental studies, digital arts and sustainable growth and development. With a current undergraduate and graduate enrollment of nearly 17,000, the campus is projected to grow to 21,000 students by 2010. Located in the heart of inland Southern California, the nearly 1,200-acre, park-like campus is at the center of the region's economic development.
