Project description:A pseudometallophyte Arabidopsis halleri is frequently found to be infected with cucumber mosaic virus (CMV) in its natural habitat. The purpose of this study is to elucidate the effect of CMV infection on its natural hosts. The CMV(Ho) strain isolated from A. halleri was inoculated into clonal A. halleri plants that were obtained from runners of mother plants, and the pathosystem consisting of CMV(Ho) and its natural host A. halleri was established.In low heavy metal environment, the CMV(Ho) infection caused growth retardation in the above-ground part (stems and leaves) of host plants, and thereby conferred strong drought tolerance on host plants. On the other hand, in high heavy metal environment, which simulates a natural habitat for A halleri, the CMV(Ho) infection did not cause any symptoms to host plants and conferred mild drought tolerance. And the result of transcriptome analysis suggests that CMV(Ho) is recognized as a symbiont rather than a pathogen by its host plant. These results indicate a resilient mutualistic interaction between CMV(Ho) and its natural host A. halleri to adapt to an environmental change.

Project description:Intra-specific polymorphism in copy number is documented in many organisms, including human and chimpanzee, but very little is known for other great apes. This study aims to provide CNVs data for orangutan, gorilla, bonobo and chimpanzee, and compare the CNV patterns among these species, as well as with human CNVs and segmental duplications from public databases.

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.

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. 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.

This study aims to provide CNVs data for orangutan, gorilla, bonobo and chimpanzee, and compare the CNV patterns among these species, as well as with human CNVs and segmental duplications from public databases. Each sample is hybridized against a common reference of the same species for two dye combinations (e.g. chimp1_CY5 vs chimpREF_Cy3; chimp1_CY3 vs chimpREF_Cy5; bonobo1_CY5 vs bonoboREF_Cy3; bonobo1_CY3 vs bonoboREF_Cy5;)

Project description:Aiming at defining the protein content and composition of a single mitochondrion of Arabidopsis thaliana, shotgun analyses were performed on purified mitochondria from cultured heterotrophic Arabidopsis cells. Based on microscopic observations on the size of mitochondria, as well as biochemical properties, such as protein concentration, average molecular mass of proteins, and the average length of the signal peptide, intensity-based absolute quantification (iBAQ) values were applied to calculate the copy number of each identified protein species within a single mitochondrion. Copy numbers of the individual proteins span five orders of magnitude, ranging from >40,000 for Voltage-Dependent Anion Channel 1 (VDAC1) to sub-stoichiometric copy numbers, i.e. less than a single copy per single mitochondrion, for several pentatricopeptide repeat (PPR) proteins that modify mitochondrial transcripts.
