Project description:Identification of differentially expressed genes in Arabidopsis thaliana mutants in response to combined abiotic stress treatment through Microarray experiment.
Project description:The success of bottom-up proteomic analysis frequently depends on the efficient removal of contaminants from protein or peptide samples before LC-MS/MS. For a peptide clean-up workflow, the single-pot solid-phase-enhanced peptide sample preparation on carboxylate-modified paramagnetic beads (termed SP2) was evaluated for sodium dodecyl sulfate or polyethylene glycol removal from Arabidopsis thaliana tryptic peptides. The robust and efficient 40-min SP2 protocol, tested for a 10 ng, 250ng and 10µg peptide sample, was proposed and benchmarked thoroughly against the ethyl acetate extraction protocol. The SP2 protocol on carboxylated magnetic beads proved to be the robust approach even for simultaneous removal of massive sodium dodecyl sulfate (SDS) and polyethylene glycol (PEG) contaminations from AT peptide samples in respect of the LC-MS/MS data outperforming ethyl acetate extraction.
Project description:We produced RNA-seq reads from messenger RNA isolated from aerial seedling tissue for Arabidopsis thaliana mutants in the HULK gene family. The read data were generated with biological replication (two replicates). The resulting RNA-seq data provide a resource to assess the function of HULK genes in the control of downstream gene expression in A. thaliana.
Project description:To identify genes of the guard cell transkriptome of Arabidopsis thaliana enriched guard cell samples were compared with total leaf tissue. Genes of the abscisic acid and humidity response of Arabidopsis thaliana guard cells were identified by treatment with ABA-Spray and low humidity. Ost1-2 and slac1-3 mutants were compared to their wildtype.
