General Information | Comment | Organism |
---|---|---|
physiological function | an isoform MT-1 homozygous mutant is non-lethal and produces 24-45% alpha-tocopherol and 55-74% beta-tocopherol as compared to 96% alpha- and 4% beta-tocopherol for wild-type | Helianthus annuus |
physiological function | isoform MT-2 compensates for the loss of isoform MT-1 function, and the MT-2 mutation profoundly affects the synthesis of tocopherols without adversely affecting the synthesis of plastoquinone crucial for normal plant growth and development | Helianthus annuus |
