Transcription profiling of Arabidopsis halleri to examine the `lMolecular bases of zinc tolerance and accumulation

ABSTRACT: This application is from a NERC-funded consortium (Mark MacNair, Nick Smirnoff, Exeter) and (Brian Ford-Lloyd, John Newbury, Birmingham). Metal tolerance is one of the classic examples of micro-evolution. Despite extensive research the physiological bases of the adaptation in plants are largely unknown. Arabidopsis halleri is a zinc tolerant, zinc accumulating species whereas Arabidopsis petraea is non-accumulating and non-tolerant. The objective of our programme is to identify:; a) those key genes that act to determine Zn tolerance and accumulation in Arabidopsis (and which account for the difference in performance of A. halleri and A. petraea grown in the presence of elevated Zn), and; b) those _downstream_ genes that are expressed as part of the tolerance or accumulation response.
