摘要
Vitamin E is thought to be involved in many essential processes in plants, but no functional proof has been reported. To study vitamin E deficiency in plants, a high-throughput biochemical screen for vitamin E quantification in Arabidopsis mutants has been developed, which has led to the identification of VTE1-encoding tocopherol cyclase. Interestingly, the corresponding maize mutation, sxd1, causes plasmodesmata malfunction, suggesting a link between tocopherol cyclase and plasmodesmata function.
