Reproductive Organ and Vascular Specific Promoter of the Rice Plasma Membrane Ca2+ATPase Mediates Environmental Stress Responses in Plants

Abstract

Background: Plasma membrane Ca 2+ ATPase is a transport protein in the plasma membrane of cells and helps in removal of calcium (Ca 2+ ) from the cell, hence regulating Ca 2+ level within cells. Though plant Ca 2+ ATPases have been shown to be involved in plant stress responses but their promoter regions have not been well studied.
