Project description:Arabidopsis has two genes, Arabidillo-1 and -2, related to animal Armadillo/ beta-catenin (Coates, 2003). Armadillo/beta-catenin directly activates the expression of developmental and cell proliferation genes, and also independently regulates cell-cell adhesion. Arabidillo proteins are nuclear and promote lateral root development. We aim to identify candidate Arabidillo target genes by comparing the transcriptomes of wild type, arabidillo-1/2 mutant and Arabidillo-1 overexpressing lines. The experiment will compare Col-0 (3 slides) with a 35S::Arabidillo-1-YFP overexpressing line (3 slides) and Col-3 with the arabidillo-1/2 mutant (3 slides). Each RNA prep will be from plate-grown 7-day old seedlings. Reference: Coates, JC (2003) Armadillo repeat proteins: beyond the animal kingdom?

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.

Project description:Entry into the S phase of the cell cycle is controlled by the E2F transcitption factors that induce the transcription of genes required for cell cycle progression and DNA replication. To identify E2F target genes of Arabidopsis on a genome-wide scale, the transcriptome of wild-type plants was compared with that one of plants ectopically expressing the E2Fa-DPa genes. In four independent experiments, E2Fa-DPa overexpressing plants were grown side-to-side with wild type (Col-0) plants. RNA was extracted from 6-day-old seedlings. Each biological sample was harvested and processed independently, and finally all probed individually to Affymetrix ATH1 microarrays, resulting into 8 hybridization signals for each probeset.
