What controls vitamin C levels in plants?
William Laing and Sean Bulley HortResearch scientists from New Zealand have identified the last remaining unknown enzyme in the major pathway of vitamin C biosynthesis in plants and have shown that this enzyme controls the level of vitamin C in leaves. In a near-simultaneous report, scientists from UCLA, working from a different approach based on their experience in the nematode worm Caenorhabditis elegans, have also reported the discovery of this enzyme. Both approaches relied on bioinformatic analysis of the predicted protein sequence of a previously identified gene that causes low vitamin C in a mutant of the model plant Arabidopsis thaliana.
