Transcript data affected by constitutive expression of VvMYBPAR in Arabidopsis

ABSTRACT: Constitutive expression of VvMYBPAR in Arabidopsis was found to accumulate proanthocyanidins when the plants were grown on sucrose-supplemented media to induce anthocyanins. To identify the putative targets of VvMYBPAR, the transcriptome analysis of the transgenic lines which highly express VvMYBPAR was carried out using NimbleGen microarray. Three transgenic lines in which VvMYBPAR were constitutively expressed under the control of 35S promoter vs. empty vector transformants were compared.

Journal of experimental botany 20140523 15

A new regulator of proanthocyanidin (PA) biosynthesis in grapes was found by screening genes coordinately expressed with PA accumulation under different light conditions using a substantially improved method of serial analysis of gene expression (SuperSAGE). This R2R3-MYB transcription factor, VvMYBPAR, shows high protein sequence similarity with PA biosynthesis-regulating plant MYBs, such as VvMYBPA2 and TRANSPARENT TESTA2. Its transcript levels were relatively high in the skins of young berrie ...[more]

Arabidopsis Polycomb Repressive Complex 2 binding sites contain putative GAGA factor binding motifs within coding regions of genes

Project description:Background. Polycomb Repressive Complex 2 (PRC2) is an essential regulator of gene expression that maintains genes in a repressed state by marking chromatin with trimethylated Histone H3 lysine 27 (H3K27me3). In Arabidopsis, loss of PRC2 function leads to pleiotropic effects on growth and development thought to be due to ectopic expression of seed and embryo-specific genes. While there is some understanding of the mechanisms by which specific genes are targeted by PRC2 in animal systems, it is still not clear how PRC2 is recruited to specific regions of plant genomes.Results. We used ChIP-seq to determine the genome-wide distribution of hemagglutinin (HA)-tagged FERTLIZATION INDEPENDENT ENDOSPERM (FIE-HA), the Extra Sex Combs homolog protein present in all Arabidopsis PRC2 complexes. We found that the FIE-HA binding sites co-locate with a subset of the H3K27me3 sites in the genome and the associated genes were more likely to be de-repressed in mutants of PRC2 components. The FIE-HA binding sites are enriched for three sequence motifs including a putative GAGA factor binding site that is also found in Drosophila Polycomb Response Elements (PREs).Conclusions. Our results suggest that PRC2 binding sites in plant genomes share some sequence features with Drosophila PREs. However, RNA was extracted from intermediate phenotype siFIE plants, clf-7 swn-28 and Col using Qiagen Plant RNeasy mini kit. For each sample, three pools of 10-12 plants were used. The siFIE plants were analysed for FIE mRNA by RT-qPCR; the maximum level of FIE mRNA was found to be 10% of wildtype.

Comprehensive analysis of genic male sterility-related genes in Brassica rapa using Brassica rapa 300k microarray v2.0

Project description:To identify genes associated with genic male sterility (GMS) that could be useful for hybrid breeding in Chinese cabbage (Brassica rapa ssp. pekinensis), floral bud transcriptome analysis was carried out using a B. rapa microarray with 300,000 probes (Br300K). Among 47,548 clones deposited on a Br300K microarray with seven probes of 60 nt length within the 3' 150 bp region, a total of 10,622 genes were differentially expressed between fertile and sterile floral buds; 4,774 and 5,848 genes were up-regulated over 2-fold in fertile and sterile buds, respectively. However, the expression of 1,413 and 199 genes showed fertile and sterile bud-specific features, respectively. Genes expressed specifically in fertile buds, possibly GMS-related genes, included homologs of several Arabidopsis male sterility-related genes, genes associated with the cell wall and synthesis of its surface proteins, pollen wall and coat components, signaling components, and nutrient supplies. However, most early genes for pollen development, genes for primexine and callose formation, and genes for pollen maturation and anther dehiscence showed no difference in expression between fertile and sterile buds. Some of the known genes associated with Arabidopsis pollen development showed similar expression patterns to those seen in this study, while others did not. BrbHLH89 and BrMYP99 are putative GMS genes. Additionally, 17 novel genes identified only in B. rapa were specifically and highly expressed only in fertile buds, implying the possible involvement in male fertility. All data suggest that Chinese cabbage GMS might be controlled by genes acting in post-meiotic tapetal development that are different from those known to be associated with Arabidopsis male sterility. A total of 14 chips were used for the microarray experiment. Experiments were performed with two biological replicates.

Gene expression profiling in senescence leaves from senescence-inducible LEC2 in Arabidopsis

Project description:The profiling was conducted with the 385K Microarray manufactured at NimbleGen, Inc (http://www.nimblegen.com/) designed from 30,386 genes of Arabidopsis (TAIR v.6). RNA samples of leaves of S1 (100% green leaf from 40 days plant) and S3 (more than 50% yellow leaf) senescence stages from senescence-inducible LEC2 transgenic plant, OIL21 were subjected for analysis of Arabidopsis 385K transcriptome. Expression of 3,025 genes were significantly changed with log2 ratios greater than 1.0 or less than -1.0 in S1 or S3 stage (p value <0.05), among which 1491 were up-regulated and 1534 were down regulated. Gene annotation revealed that 7.4% genes, 223 out of 3,025 changed by LEC2 were encoded transcription factors (TF). 106 TFs were up-regulated and 115 TFs were down-regulated. A total of 9 chips were used for microarray. Total RNAs were extracted from senescence leaves at S1 and S3 stages of wild-type and senescence-inducible LEC2 transgenic Arabidopsis. Experiments were triplicated.

Nucleosome occupancy changes in mammalian cell differentiation and reprogramming (microarray)

Project description:Embryonic stem cells (ESCs) and induced-pluripotent stem cells (iPSCs) self-renew and differentiate into an array of cell types in vitro and in vivo. A complex network of genetic and epigenetic pathways regulates the self-renewal and differentiation of these pluripotent cells, and the structure and covalent modifications of chromatin play a prominent role in this process. We examine nucleosome occupancy in mouse and human embryonic stem cells (ESCs), induced-pluripotent stem cells (iPSCs), and differentiated cell types using MNase-seq. To address variability inherent in this technique, we developed a bioinformatic approach that enabled the identification of regions of difference (RoD) in nucleosome occupancy between pluripotent and somatic cells. The majority of changes in nucleosomal signatures that occur in differentiation are reset during reprogramming. We conclude that changes in nucleosome occupancy are a hallmark of pluripotency and likely identify key regulatory regions that play a role in determining cell identity.
