Project description:Transcriptional profiling of Arabidopsis thaliana seedlings treated with cis-cinnamic acid derivatives constructed by Nishikawa et al. (2013) Phytochemistry (http://dx.doi.org/10.1016/j.phytochem.2013.08.013), evaluating the candidate of herbicide chemicals by observing early response of gene expressions in Arabidopsis seedlings.
Project description:Using whole genome microarray (Affymetrix ATH1) we studied the transcriptional response of Arabidopsis thaliana to triazolopyrimidine (FirstRate) herbicde that inhibits acetolactate synthase (ALS) enzyme and thus disrupts branched chain amino acid biosynthesis. A number of genes related to amino acid, protein metabolism, growth, regulatory networks, respiratory pathways, stress, defense and secondary metabolism were altered. Experiment Overall Design: Surfactant (preference 0.25%) treated plants were used as carrier control group and EC50 concentration of triazolopyrimidine was used as the herbicide treatment group. Each of the control and treatment group consisted of 3 biological replicates and each biological replicates comprised leaves from 10 individual plants. RNA was extracted at 24h post treatment to study the transcriptional alterations caused by the herbicide treatment.
Project description:Using whole genome microarray (Affymetrix ATH1) we studied the transcriptional response of Arabidopsis thaliana to primisulfuron (Beacon) herbicde that inhibits acetolactate synthase (ALS) enzyme and thus disrupts branmched chain amino acid biosynthesis. A number of genes related to amino acid, protein metabolism, growth, regulatory networks, respiratory pathways, stress, defense and secondary metabolism were altered. Experiment Overall Design: Surfectant (preference 0.25%) treated plants were used as carrier control group and EC50 concentration of primisulfuron was used as the herbicide treatment group. Each of the control and treatment group consisted of 3 biological replicates and each biological replicates comprised leaves from 10 individual plants. RNA was extracted at 24h post treatment to study the transcriptional alterations caused by the herbicide treatment.
Project description:To understand the role of GCN2 in regulating translation, we compared the polysome loading state and overall transcript level between Arabidopsis thaliana wild type (ecotype Landsberg erecta) and gcn2 (Genetrap line GT8359, Cold Spring Harbor Laboratory) seedlings with or without herbicide chlorosufuron treatment RNA was fractionated using sucrose gradients into polysomal and nonpolysomal RNAs. We also determined overall total transcript levels. We used Affymetrix ATH1 microarrays.
