Abstract

This thesis explores three aspects regarding Hakea prostrata (Proteaceae) adaptations to its phosphorus (P)-impoverished natural environment. These include the P-efficient strategy of delayed leaf greening and the P-acquisition strategy of cluster roots. Lastly, it investigated the P-sensitivity phenomena that is shared among many Proteaceae and other Australian species. In leaves, it describes the delayed upregulation of genes involved in photosynthesis and the shift from cytosolic to chloroplastic ribosomal subunit genes. In cluster roots, it highlights proteins involved in carboxylate production. It also describes how attenuated regulation of PHOSPHATE TRANSPORTER1 gene expression may lead to the P-sensitivity seen in this species.
