isoform Hpt1 is strongly regulated by dark and low-temperature. Under the same treatments, alpha-tocopherol increases in cultures exposed to darkness or heat, whereas gamma-tocopherol does it in low temperature |

the expression patterns of the five tocopherol biosynthetic genes vary in different plant tissues and under different stress conditions. All five genes are highly expressed in leaf tissues, whereas 4-hydroxyphenylpyruvate dioxygenase and homogentisate phytyltransferase are highly expressed in the thick roots. The expression patterns of these five genes significantly differ in response to PEG, NaCl and H2O2-mediated oxidative stress. Homogentisate phytyltransferase is strongly induced following PEG treatment |

abiotic stress results in an 18 and 8fold increase in total tocopherol content in wild-type and isoform HPT1 overexpressing leaves, respectively, with tocopherol levels in the ovrexpressing strain being 2- to 4fold higher than wild type at all experimental time points. Increased total tocopherol levels correlate with elevated HPT mRNA levels and HPT specific activity |
