Mutations of the ER to plastid lipid transporters TGD1, 2, 3 and 4 and the ER oleate desaturase FAD2 suppress the low temperature-induced phenotype of Arabidopsis tocopherol-deficient mutant vte2.

Abstract excerpt

Previous studies with the tocopherol-deficient Arabidopsis thaliana vte2 mutant demonstrated an important role for tocopherols in the development of transfer cell walls and maintenance of photoassimilate export capacity during low-temperature (LT) adaptation. To further understand the processes linking tocopherol deficiency and the vte2 LT phenotypes, a genetic screen was performed for sve mutations (suppressor...
