Mechanisms Of Zinc Transport And Homeostasis In The Plant, Arabidopsis

Grant number: DP0556747

Abstract

Zinc-deficiency is one of the most widespread factors limiting crop production and affects many soils of south-east and south-west Australia. Certain zinc-efficient (ZE) crop cultivars are able to grow well under zinc deficient conditions but the genetic basis for ZE is not well understood. Using a model organism such as Arabidopsis to identify genes in plants that are important in zinc transport and homeostasis will ultimately allow us to assess whether the homologous genes in crop species are responsible for ZE. This may contribute to more rapid and directed strategies in breeding ZE crop cultivars.
