Maize yellow stripe1 and related genes

摘要

The maize yellow stripe1 gene encodes a transmembrane protein which mediates the uptake of chelated iron from soil. The gene is shown here to be upregulated, and protein production increased, under conditions of low iron bioavailability. The protein is also shown to be able to transport other metals as well, such as copper. The present invention also provides a family of Arabidopsis genes and gene products related to ys1 termed here as ys11-8. The invention provides the genes and their gene products as well as methods to create and use transgenic plants for the increased uptake of iron in nutritional crops as well as for the bioremediation of soil.
