Interestingly, the abc1k3 cluster colocalized with the a-tocopherol (a-T) oxidativederivate a-tocopherol quinone (a-TQ) but not with the other tocopherols, which were typical of wild-type samples.On the contrary, vte1 samples colocalized with the xanthophyll lutein and the tocopherol precursor 2,3-dimethyl-5-phytyl-1,4-hydroquinone (DMPBQ).
