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]

High-throughput SuperSAGE for transcript profiling in berry tissues of Vitis vinifera L. under different light regimes

Project description:SuperSAGE is a method of digital gene expression profiling that allows isolation of 26bp tag fragments from expressed transcripts. Because its tag size is larger than that of conventional SAGE, SuperSAGE allowed a secure tag-to-gene annotation using BLAST search against grape genome databases.Transcript profiles in nine samples of grape berry tissues under different light conditions were obtained by SuperSAGE analysis and used for screening the genes which have co-ordinated transcript profiles with the change in the flavonoid composition in the samples analyzed. Candidate genes related to flavonoid biosynthesis and regulation were identified. Nine different grape samples, i.e., flowers, grape berries of Cabernet Sauvignon at 2, 7, 9 weeks after flowering (WAF), berry skins at 17 days after flowering (DAF) shaded after flowering, and berry skins at 17DAF shaded from flowering to 14DAF and then light exposed, were analyzed.

Microarray analysis of male strobili in fertile and sterile male strobili of Cryptomeria japonica

Project description:Investigation of comprehensive gene expression level changes in male strobili of sterile mutant, compared to the fertile plant. We designed a new custum array derived from ESTs of Cryptomeria japonica for this study. Male strobili of C. japonica were collected from Toyama 1 half-sib F2 pedigree. Toyama 1 male-sterile mutant was first reported in Saito, M. , H. Taira, and Y. Furuta (Journal of Forest Research 3(3):167-173). Microarray studies using both individual samples and pooled samples were performed. Total RNA was extracted from male strobili at four developmental stages derived from each seven fertile and male-sterile trees as individual samples. Pooled RNA samples were prepared from four to eight different fertile and sterile plants at three developmental stages.

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.

Comparative study of transcriptomes from four Trichoderma strains gene expression in early interaction with tomato plants

Project description:A self-designed Trichoderma high density oligonuclotide (HDO) microarray (Roche-NimbleGen, Inc., Madison, WI, USA) was constructed in a similar way than a previous Trichoderma HDO microarray (Samolski et al., 2009). The microarray was composed of 392,779 60-mer probes designed against 14,081 EST-derived transcripts (Trichochip-1) and the genomes of T. reesei (9,129 genes) and T. virens (11,643 genes). The Trichochip-1 ESTs were obtained from 28 cDNA libraries from eight different species (representing the biodiversity of this genus: T. harzianum, T. atroviride, T. asperellum, T. viride, T. longibrachiatum, T. virens, T. stromaticum and T. aggresivum), under a wide range of growth conditions, including biocontrol-related conditions and different nutritional situations (VizcaM-CM--no et al., 2006). This HDO microarray was used to analyze Trichoderma spp. transcriptomes after 20 h incubation in the presence of tomato plants. The Trichochip1 EST database was generated in the TrichoEST project funded by the EU (QLK3-CT-2002-02032). Eight samples were analyzed as follows: Strain T. reesei T6 grown in the presence or not of tomato plants, strain T. hamatum T7 grown in the presence or not of tomato plants, strain T. harzianum T34 grown in the presence or not of tomato plants and strain T. virens T87 grown in the presence or not of tomato plants. Three replicates for each samples were performed.

Increasing the source/sink ratio in Vitis vinifera (cv Sangiovese) induces extensive transcriptome reprogramming and modifies berry ripening

Project description:Background: Cluster thinning is an agronomic practice in which a proportion of berry clusters are removed from the vine to increase the source/sink ratio and improve the quality of the remaining berries. Until now no transcriptomic data have been reported describing the mechanisms that underlie the agronomic and biochemical effects of thinning. Results: We profiled the transcriptome of Vitis vinifera cv. Sangiovese berries before and after thinning at veraison using a genome-wide microarray representing all grapevine genes listed in the latest V1 gene prediction. Thinning increased the source/sink ratio from 0.6 to 1.2 m2 leaf area per kg of berries and boosted the sugar and anthocyanin content at harvest. Extensive transcriptome remodeling was observed in thinned vines 2 weeks after thinning and at ripening. This included the enhanced modulation of genes that are normally regulated during berry development and the induction of a large set of genes that are not usually expressed. Conclusion: Cluster thinning has a profound effect on several important cellular processes and metabolic pathways including carbohydrate metabolism and the synthesis and transport of secondary products. The integrated agronomic, biochemical and transcriptomic data revealed that the positive impact of cluster thinning on final berry composition reflects a much more complex outcome than simply enhancing the normal ripening process. Total RNA recovered from a pool of berries derived from three control plants (C) was compared to total RNA from a pool of berries derived from three cluster thinned vines (50% of cluster removed) at beginning of véraison (BV), end of véraison (EV) and harvest (H). For each sampling date microarray analyses were conducted for three different biological replicates for treatment.

Transcript data affected by constitutive expression of VvMYBPAR in Arabidopsis

Project description: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.

Transcriptome analysis of deletion of adenylate cyclase in T. reesei upon growth on cellulose in light and darkness

Project description:The aim of this study was to evaluate changes in the transcriptome due to the lack of adenylate cyclase in light or darkness. As the cAMP pathway represents an output pathway of heterotrimeric G-protein signaling ACY1 is likely to be important for regulation of enzymes in response to different nutrient conditions. Also, a light dependent effect was found earlier. Strains of this study were grown on Mandels Andreotti Minimal Medium with 1 % w/v microcrystalline cellulose as sole carbon source in constant light or constant darkness for 72 hours; 2 biological replicates were included
