Project description:To examine differential effect of the mutation of Arabidopsis TGA7 on the gene expressions, we performed microarray analysis using the shoots or the root of wild-type and tga7 mutant.
Project description:Regulation of genes in shoots and roots and Arabidopsis in response to Zn-deficiency in wild-type and hma2 hma4 mutants plants We used microarrays to determine co-regulated genes in the roots of Zn deficient wild-type plants with hma2 hma4 plants from control conditions. These co-regulated genes are candidates for regulation by a systemic signal
Project description:Bulk RNA-seq data data sets were generated for mutant and wild-type roots of 7 day old plants, with and without cytokinin treatment
Project description:Using a dedicated split-root approach, we identified miRNAs regulated systemically by nitrogen availability in both shoots and roots of the Medicago truncatula model legume, depending on the CRA2 pathway, highlighting the phosphate-related miR399.
Project description:Gene expression profiles of drought-stressed roots and shoots was performed at 0, 1, 3, 5, 7 and 9 days were analyzed using the custom microarray Agilent-034592.
Project description:Root architectural plasticity enables rice to adapt to fluctuating soil water conditions. PP2CABA is an abscisic acid-inducible clade F2 protein phosphatase that regulates rice root development, lignin and suberin deposition, and adaptation to drought and flooding stress. We used Affymetrix Rice GeneChip microarrays to compare transcriptomic profiles between wild-type rice roots and roots of XVE:PP2CABA-dHA transgenic rice seedlings following β-estradiol induction. This analysis was performed to identify genes and pathways regulated by PP2CABA in rice roots, particularly those associated with cell wall modification, phenylpropanoid biosynthesis, fatty acid elongation, and lipid transfer.
Project description:This study aims to identify genes which are differentially expressed in root and/or shoot material in response to exogenous cytokinin. Roots and shoots were collected separately.
Project description:IRT1 is the root high-affinity Fe uptake system. Despite severe Fe deficiency symptoms and reduced Fe levels in the shoots of irt1 mutants, we find that root Fe concentrations are higher in the irt1-2 mutant than in the wild type, unexpectedly. The goal of this experiment was to identify candidate transcripts contributing to the observed alteration in root-to-shoot Fe partitioning of irt1. We analysed gene expression in shoots and roots of the wild type grown under control conditions, the wild type exposed to severe Fe deficiency for 5 d, as well as of the irt1-2 (pam42) mutant grown under control conditions.
