Vesicle-related OsSEC27P enhances H+ secretion in the iron deficient transgenic tobacco root

Article Plant Cytology


Iron is an essential micronutritional element for plants. In addition to the iron uptake mechanism Strategy I and Strategy II, the vesicle transport process was also found to participate in iron uptake and homeostasis. Herein, a new iron deficiency induced OsSEC27P gene was isolated and investigated in both its localization and its function in transgenic plants. The vesicle-related protein OsSEC27P may play a potential role in enhancing H+ secretion in roots under the iron deficiency conditions.
