Abstract

K supply impacts on crop yield and nutritional quality. K acquisition and allocation within plants is tightly controlled in order to protect K levels in the cytoplasm of metabolically active cells against fluctuating K supply in the root environment. Although K homeostasis is crucial for plant growth the underlying regulatory mechanisms are poorly understood. I propose to employ oligonucleotide chip technology to obtain a comprehensive picture of K dependent expression clusters of membrane transporter genes. This knowledge will be used to identify components of K perception and signalling by (i) pharmacologically characterising the expression response and (ii) screening for mutants with altered transgene (luciferase) expression.
