Project description:We set out to test the hypothesis that there is a sensing system in plants that perceives herbicides resulting in transcriptome changes that lead to the expression of genes encoding proteins that detoxify these molecules. We show that chlorsulfuron-treatment induces changes in the Marchantia polymorpha transcriptome. However, these transcriptome changes do not occur in target site resistant mutants treated with chlorsulfuron. Instead, we show that inactivation of the chlorsulfuron target, acetolactate synthase (ALS) (also known as acetohydroxyacid synthase (AHAS)), is required for the transcriptome response.

Global expression profiling to study the effect of triazolopyrimidine herbicide treatment on Arabidopsis thaliana

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. Keywords: Acetolactate synthase (ALS) inhibiting herbicide stress response

Global expression profiling to study the effect of imidazolinone herbicide treatment on Arabidopsis thaliana

Project description:Using whole genome microarray (Affymetrix ATH1) we studied the transcriptional response of Arabidopsis thaliana to imidazolinone (Arsenal) 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. Keywords: Acetolactate synthase (ALS) inhibiting herbicide stress response

Global expression profiling to study the effect of primisulfuron herbicide treatment on Arabidopsis thaliana

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. Keywords: Acetolactate synthase (ALS) inhibiting herbicide stress response

Sorghum bicolor, BTx623 RNA-Seq - Conserved Poaceae Specific Genes Project

Project description:The Poaceae family, also known as the grasses, includes agronomically important cereal crops such as rice, maize, sorghum, and wheat. Previous comparative studies have shown that much of the gene content is shared among the grasses; however, functional conservation of orthologous genes has yet to be explored. To gain an understanding of the genome-wide patterns of evolution of gene expression across reproductive tissues, we employed a sequence-based approach to compare analogous transcriptomes in species representing three Poaceae subgroups including the Pooideae (Brachypodium distachyon), the Panicoideae (sorghum), and the Ehrhartoideae (rice). Our transcriptome analyses reveal that only a fraction of orthologous genes exhibit conserved expression patterns. A high proportion of conserved orthologs include genes that are upregulated in physiologically similar tissues such as leaves, anther, pistil, and embryo, while orthologs that are highly expressed in seeds show the most diverged expression patterns. This experiment is related to E-MTAB-4401 (http://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-4401/) and E-MTAB-4402 (http://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-4402/)
