Study Finds Regulating Key Enzyme Activity Can Increase Folate Levels in Tomatoes

Researchers have discovered that controlling the activity of a specific enzyme can increase the folate content in tomatoes. This study, published in Horticulture Research, compared and analyzed two different tomato varieties -one with naturally high folate and one with low.
By analyzing the differences in genes, enzymes, metabolites and nutrients between the two tomatoes during ripening, the research team spotted key differences. The high-folate tomato Periyakulam-1 had lower gamma-glutamyl hydrolase activity, resulting in less breakdown of folate.
The researchers indicate that regulating gamma-glutamyl hydrolase activity could be a strategy for biofortifying crops like tomato to increase their nutritional value. As a globally important economic crop, increasing folate levels in tomatoes through selective breeding or other approaches would have significant implications for improving human health and agricultural sustainability.
