Arabidopsis thaliana WRKY family comprises 74 members and some of them are involved in plant responses to biotic and abiotic stresses. This study demonstrated that WRKY6 is involved in Arabidopsis responses to low-Pi stress through regulating PHOSPHATE1 (PHO1) expression. WRKY6 overexpression lines, similar to the pho1 mutant, were more sensitive to low Pi stress and had lower Pi contents in shoots compared with wild-type seedlings and the wrky6-1 mutant. Immunoprecipitation assays demonstrated ...[more]

DUO1 ectopic expression

Project description:The experiment is designed to examine changes in gene expression upon ectopic expression of the germ line transcription factor DUO1 in Arabidopsis. Plants were transformed with the vector pMDC7DUO1, allowing induction of DUO1 by treatment with estradiol. T2 seedlings were selected on agar plates containing hygromycin for 12 days before seedlings were transferred to plates containing either 2 µM 17beta-estradiol (induced), or control plates containing DMSO (non-induced). Plants were grown for 6, 12 or 24 hours before harvesting. RNA was extracted using the RNAeasy kit from Qiagen. Each sample consists of 20 seedlings combined and all treatments have been conducted in triplicate. 18 samples were used in this experiment.

Polycomb mutant seedlings

Project description:We have identified a histone methyltransferase gene CURLY LEAF (CLF), which is required to repress a floral homeotic gene AGAMOUS (AG). CLF acts redundantly with a related gene SWINGER (SWN), so that clf swn double mutants have extreme, near lethal phenotypes in which expression of many target genes is disrupted. To understand better when and where these genes act, we propose to use a system for generating mosaic plants in which marked sectors of cells are created that gain or lose CLF (or other Pc-G) gene function in SWN+ and swn- mutant backgrounds. This will allow us to address questions such as whether the Pc-G genes are needed throughout development to silence their targets, whether they are needed once cell division has ceased, whether they can silence their targets once the targets have been activated, and whether genes that are epigenetically silenced by CLF are impervious to activating factors. Aim is to compare gene expression in wild-type and polycomb mutant seedlings. Comparison of bulked seedlings of four genotypes: wild-type (Columbia), clf-28, swn-7, clf-28 swn-7 double mutant. 8 samples were used in this experiment, 2 of each genotype. Tissue grown in tissue culture.

Expression data from aerial parts of 14-day-old wild-type and GFP-TIE1-15 Arabidopsis seedlings

Project description:TIE1 regulates leaf development by repressing leaf differentiation because the semi-dominant mutant tie1-D by activation tagging displays small and hyponastic leaves and the differentiation of leaf epidermal cells is delayed in the tie1-D mutant, whereas disruption of TIE1 causes epinastic leaves with early differentiated epidermal cells. We used microarrays to investigate the molecular base underpinning the phenotypes of TIE1-overexpressing plants. Aerial parts of 14-day-old seedlings from wild-type and GFP-TIE1-15 were collected for RNA extraction and hybridization on Affymetrix microarrays.

Expression data from 7-day-old Arabidopsis emf2 mutant, rescued emf2 mutant harboring 35S::BoEMF2.1, WT Columbia ecotype and WT harboring 35S::BoEMF2.1 named transWT

Project description:Arabidopsis emf2 mutants bypass vegetative development and flowering upon seed germination. We introduced a broccoli BoEMF2.1 gene into emf2 mutants and obtained rescued emf2 plants that harbored 35S::BoEMF2.1. We found that BoEMF2.1 can partially rescue the phenotype of emf2 to that of WT. We used microarrays to study the global program of gene expression and to identify genes misexpressed in the Arabidopsis emf2 mutant that had been rescued by 35S::BoEMF2.1. 7-day-old seedlings of WT, transWT, emf2 and rescued emf2 Arabidopsis were used for RNA extraction and hybridization on Affymetrix microarrays.

Transcription profiling by array of Nipponbare rice roots over a time course of potassium deprivation

Project description:Potassium (K+) is one of the most important nutrient ions in plant cells and play crucial roles in many plant physiological and developmental processes. K+ deficiency is the common abiotic stress in natural environment, which inhibits plant growth and reduces production of crops. We used microarrays to analyse the transcriptomic changes in rice roots after suffering K+ starvation at different times. The results of GO analysis showed that these transcriptionally changed genes mainly fell into the categories of metabolic process, membrane, cation binding, kinase activity, transport and so on. The two-week-old hydroponic rice seedlings were transferred to K+-free solution (-K) and K+-replete solution (+K, 1 mM K+) as treatment (LK) and control (CK) conditions respectively. The fresh roots of both control and treated rice seedlings were collected after K+-deficient treatment at indicated times (6 h, 3 d and 5 d). The roots were frozen immediately using liquid nitrogen and stored at -80℃ for further RNA extraction. Every RNA sample was derived from 5 independent seedlings. In sum, three time points were selected and three biological replicates were performed at each time point, totally 18 rice genome arrays were used.

Nuclear gene expression in response to chloroplast division inhibition

Project description:The aim of this investigation is to analyse the effect on nuclear gene expression of inhibition of chloroplast division. Transgenic Arabidopsis lines (Ler) were generated that contained a chemically inducible promoter (XVE) upstream of AtMinD1. AtMinD1 encodes a product involved in chloroplast division; overexpression of AtMinD1 leads to chloroplast division inhibition. 6 samples were used in this experiment. Three treatments were performed: Treatment 1: Empty vector control seedlings (transformed with PER-10 only) were sown onto lehle, sprayed at 13 days old with 2uM 17-B-estradiol (inducer) and harvested 24 hours later. Treatment 2: Seeds were sown on lehle containing inducer and sprayed every 24 hours with 2uM inducer until harvested at 14 days old. Treatment 3: Seeds were sown on lehle plates, sprayed at 13 days old with 2uM inducer and harvested 24 hours later. For all three treatments, seedlings were grown in constant light conditions, and tissue was harvested from 14-day-old seedlings (4 rosette leaves) and snap frozen in liquid nitrogen before RNA preparation.

Photoreceptor control of shoot meristem activity and leaf initiation

Project description:When Arabidopsis seedlings are grown in the dark, their shoot meristem remains in a repressed state and does not develop leaves. The tight control of leaf development by light provides the opportunity to analyse a fundamental plant developmental process in its very early stages. We have observed that activation of photoreceptors in dark-grown seedlings leads to a rapid and dramatic increase in mitotic activity in and around the shoot meristem. Cotyledons also exhibit an induction of cell cycle activity by light, but this consists of endoreduplication and occurs later. Many other processes take place upon induction by light, including the development of the photosynthetic apparatus and the synthesis of sunscreens, but these processes are expected to take place in both the leaf primordia and the cotyledons. We have used this information to carry out a whole transcriptome analysis of shoot meristem activation and early stages of leaf development by light. For this we dissected the shoot apical regions from seedlings grown in the dark or 1, 2, 6, 24, 48 or 72 h after transfer to light. We also dissected cotyledons from equivalent seedlings grown in the dark or 1 or 6 h after transfer to light. From these samples we obtained RNA used for hybridisations against the ATH1 GenChip. 16 samples were used in this experiment.

NPA-induced vascular overgrowth in Arabidopsis

Project description:We used N-(1-naphthyl) phthalamic acid (NPA)-induced vascular overgrowth in Arabidopsis leaves to look for differential up-regulation of genes in NPA-treated tissues that may be involved in vascular differentiation. Arabidopsis thaliana Col-0 plants were grown for approximately 2 weeks on solid ATS medium (1) containing a final concentration of 10 um NPA (dissolved in DMSO) or an equivalent volume of DMSO (control). At this stage plants had approximately 6 rosette leaves. RNA was prepared from entire shoot tissues of control (DMSO) or NPA-treated plants.(1) Lincoln et al., 1990. Plant Cell 2: 1071-1080. 2 samples were used in this experiment.
