Project description:Identification of new and unpredicted full length Arabidopsis genes. Examination of cRNA prepared from Arabidopsis thaliana ecotype Columbia light grown 7-day old seedlings, light grown 7-day old seedlings treated at 4 degrees C for 24hrs, and etiolated 7-day old seedlings using pilot genome tiling arrays. Total RNA was isolated from seedlings with the TRIzol reagent procedure of Invitrogen, then poly(A)+ RNA was purified with Qiagen oligotex. One microgram poly(A)+ RNA was converted into ds-cDNA using T7-oligo(dT) primers. Biotin-labeled cRNA was generated by in vitro transcription reactions using ENZO labeling kit, fragmented and then 20 micrograms of fragmented cRNA were hybridized to the arrays according to Affymetrix instructions.

Project description:Transcriptional profiling of Arabidopsis overexpressing VuDREB2A (full length/truncated) compared to wild type. Unstressed three week-old whole seedlings were used. Goal was to search the genes upregulated byVuDREB2A in Arabidopsis.
Project description:In this study, we used Arabidopsis root extracts, spiked with amide nitrogen labeled (15N1) Glutamine and a purified recombinant protein, both full length and glutaminase domain only versions, to determine the amido group acceptor, if any, in the glutamine amidotransferase reaction.
