Project description:Transcriptional profiling in the shoot after SHR induction by DEX. We used Affymetrix ATH1 microarrays to identify new target genes of SHR and the effect of SHR on growth and development of the Arabidopsis shoot system by global transcriptome analysis.

Project description:The goals of this study is to compare the differently expressed genes in abdominal aorta tissue of WKY and SHR as well as differently expressed genes in the abdominal aorta tissue of SHR with or without neferine treatment. The rat (n=15) were randomly divided into 3 groups: WKY,SHR, and SHR + neferine - H (high concentration) groups (n=6 for each group). Rat in WKY and SHR groups were intragastrically with double distilled water (dd H2O); while rat in SHR + SHR + neferine - H groups were intragastrically with 10mg/kg/D of neferine for 10 weeks. Then the abdominal aorta were used to identify differentially expressed genes among different groups.

Project description:SHR is a key regulator of stem cell renewal and radial patterning in the Arabidopsis root. In previous studies we showed that the SHR is a transcriptional regulator and it regulates gene transcription directly. To fully understand the SHR developmental pathway, we aim to identify its direct target at the genome scale using the ChIP-on-chip method. To this end, we have designed a promoter microarray for Arabidopsis, which contains probes that tile the intergenic regions as well as the first intron and the 3' UTR for all annotated genes including miRNA genes. Chromatin immunoprecipitation (ChIP) was performed using an anti-GFP antibody on the root of a transgenic line expressing under the SHR promoter a functional fusion protein between SHR and GFP. After labeling with Cy5 and Cy3 respectively, DNA recoverd from the ChIP and mock experiments was hybridized to the same microarray. The array was scanned using an Agilent scanner and the signal intensity for each channel was retrieved and normalized by the Agilent feature extraction software.

Project description:Transcriptional profiling of the vegetative part of Arabidopsis comparing wild type with the shr scl23 scr triple mutant. The latter is produced by crossing the strong null alleles of shr (shr-2), scl23 (scl23-1) and scr (scr-5). The goal was to determine the effects of the GRAS transcription factors SHR, SCL23 and SCR on growth and development of the Arabidopsis shoot system by global transcriptome analysis.

Project description:Asymmetric division of cortex/endodermal initials (CEI) in the Arabidopsis root generates two layers of ground tissue and is controlled by a finely orchestrated interplay between the transcription factors, SHORT ROOT (SHR) and SCARECROW (SCR). To understand the dynamics of the SHR/SCR regulatory network we performed microarray time course experiments using inducible versions of SHR and SCR and examined their transcriptional effects specifically in the ground tissue. Keywords: SHR and SCR time course and CEI cell-type analyses

Project description:Hydrogen peroxide (H2O2) is a potent signaling molecule influencing various aspects of plant growth and development. Its limited lifetime and specific production sites in the plant cell necessitate the existence of specialized mechanisms that relay H2O2-encoded information. To discover such mechanisms, we focused on peroxisomal H2O2 production triggered by enhanced photorespiration in Arabidopsis mutants lacking catalase activity (cat2-2), and looked for second-site mutations that attenuate the negative effects (Fv'/Fm' decline and lesion formation) of H2O2 build up. A mutation residing in the GRAS family transcriptional regulator SHORT-ROOT (SHR) was found to underlie the increased performance of cat2-2 knock-outs under photorespiratory stress. In contrast to shr, introduction of the scr mutation in cat2-2 background did not improve the photorespiratory performance of plants lacking peroxisomal catalase. The absence of SHR negatively affected the activity of the photorespiratory enzymes glycolate oxidase and catalase, which was accompanied with elevated glycolate content and inability to accumulate glycine under conditions promoting photorespiration. The transcriptome signature of cat2-2 shr-6 double mutants exposed to photorespiratory stress lacked jasmonate-dependent signaling components, otherwise induced in cat2-2. The photorespiratory phenotype of cat2-2 was found to be modulated by exogenous sugars both in the presence and absence of shr. Taken together, these findings highlight a crucial role for SHR in H2O2 signal transduction and stress tolerance.
