Project description:The model Zn hyperaccumulators Arabidopsis halleri and Noccaea caerulescens share elevated nicotianamine synthase (NAS) expression relative to non-accumulators among a core of alterations in metal homeostasis gene expression. Suppression of AhNAS2 expression by RNAi resulted in strongly reduced root NA accumulation and a concomitant decrease in root-to-shoot-translocation of Zn but not of other micronutrients. Few secondary effects on the root transcriptome were detected by microarray analysis.

Project description:The model Zn hyperaccumulators Arabidopsis halleri and Noccaea caerulescens share elevated nicotianamine synthase (NAS) expression relative to non-accumulators among a core of alterations in metal homeostasis gene expression. Suppression of AhNAS2 expression by RNAi resulted in strongly reduced root NA accumulation and a concomitant decrease in root-to-shoot-translocation of Zn but not of other micronutrients. Few secondary effects on the root transcriptome were detected by microarray analysis. Vegetatively propagated clones of A. halleri wildtype plants and a line with strong suppression of AhNAS2 were grown hydroponically for weeks in two different media (control Hoagland and 10 µM Zn2+ added). Roots were harvested and analyzed. Three plants were pooled for one sample. Three independent experiments were performed.

Project description: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. Phase 1: Total of 24 chips: Material ready by May 2003. The results will: a) tell us how effectively material derived from other Arabidopsis species hybridises to the chips, and b) identify genes that are differentially expressed in the two species in the presence and absence of Zn stress (thus providing initial lists of genes that may be responsible for Zn tolerance or accumulation- (but see phase 2). A. halleri exposed to low and high Zn; root and leaf mRNAs extracted: 3 replicates of each: = 12 slides. A. petraea exposed to low and high Zn; root and leaf mRNAs extracted: 3 replicates of each: = 12 slides. Phase 2: Total of 48 chips: Material ready by September 2003. The results will tell us which genes, identified as having appropriate expression patterns, co-segregate with the Zn tolerance or accumulation phenotype and will provide firmer candidate genes for intensive study. Bulks will be produced from F3 progeny (from the halleri x petraea cross) following phentoypic analyses for Zn tolerance and accumulation. A bulk of F3 progeny all exhibiting high Zn tolerance: exposed to low and high Zn; leaf and root mRNAs: 3 replicates: = 12 slides.
