Project description:Illumina HiSeq technology was used to generate mRNA profiles from two strains of Trametes versicolor. Mycelium of Trametes versicolor BRFM1218 and Trametes versicolor 1956-1252 were harvested after 2 and 4 weeks of incubation on 4% malt agar medium and used for total RNA extraction. Paired-end reads of 100 bp were generated and aligned to Trametes versicolor (https://mycocosm.jgi.doe.gov/Trave1/Trave1.home.html) reference transcripts using CLC Genomics Workbench 7.5.1.

Project description:The Trametes versicolor genome is predicted to encode many enzymes that can effectively degrade lignin, making it a has potentially useful application intool for biopulping and biobleaching. Poplar is an important and widely cultivated species of tree species, which isand extensively applied used in the pulping industry. However, the wood degradation mechanism of T. versicolor from transcriptomic level is not clear. To reveal identify the enzymes that contributeing to lignocellulose degraredauction and its degradation mechanisms, we evaluated transcriptomic how study theof T. versicolor transcriptome was changes during evaluated growthing on the poplar wood relative to growth on glucose medium. 853 genes were differentially expressed;, 360 genes were up-regulated on poplar wood, and 493 genes were down-regulated on poplar wood. Notably, most genes relative involved into lignin degradation were up-regulated, including eight lignin peroxidase (LiP) genes, and two manganese peroxidase (MnP) genes etc. Genes encoding cellulose and hemicelluloses degrading-enzymesation were mostly down-regulated, including six endo-β-1, 4-glucanase genes, three cellobiohydrolase I genes, and one cellobiohydrolase II gene, etc. MeanwhileAdditionally, expression of more significant expansion of P450s in T. versicolor genome, along with differences in carbohydrate- and lignin-degrading enzymes, could bewere correlated withto poplar wood degradation. Our results revealed transcriptomic characterizeation transcriptomic changes related toof lignocellulose degradation. Therefore, our results cwould be benuseful for the development ofefit T. versicolor as a tool to improve the efficiency of lignin degradation, and provide a theoretical foundation for a new paper pulp manufacturing processe 1,T.versicolor groewn on PDA medium. 2, T. versicolor growing on the a glucose carbon medium of glucose. 3, T. versicolor growing on poplar medium

Project description:In order to investigate the physiological and biochemical characteristics and molecular mechanisms during the leaf colour change of Acer rubrum L, this study used Acer rubrum L. 'Autumn Blaze' cuttings as material and analysed the transcriptome and miRNAs of Acer rubrum L leaves under different light and temperature treatments. The transcriptome and miRNAs of Acer rubrum L leaves were analysed under different light and temperature treatments, and miRNA-mRNA association analysis was performed for the differentially expressed mRNAs and miRNAs.

Project description:We performed RNA-Seq technology for quantification of differential expression of cacao cell suspensions under light/dark conditions. By obtaining over 15 millions of reads per sample, we cuantified the differential gene expression in structural, regulatory and light signaling genes associated with flavonoid biosynthesis. Our results indicated that light treatments can effectively regulate flavonoid profiles, shifting catechin - epicatechin ratios, in particular as a response to switching from white to blue light. The results demonstrated that HY5, MYB12, ANR and LAR were differentially regulated under light/dark conditions and could be targeted by overexpression aiming to improve catechin synthesis in cell cultures. Additionally, co-expression analyses of late flavonoid biosynthetic genes ANS, ANR and LAR showed a larger number of shared partners in the dark compared to selective partners in white-blue treatment. In conclusion, our RNA-Seq analysis of cacao cells cultured under different light conditions provides a platform to dissect key aspects into the genetic regulatory network of flavonoids. These light-responsive candidate genes can be used further to modulate the flavonoid production in in vitro systems with value-added characteristics.

Project description:Background: Production of biofuels and bioproducts from lignocellulosic material is limited due to the complexity of the cell wall structure. This necessitates the use of physical, chemical, and/or physico-chemical pretreatment technologies, which adds significant capital, operational, and environmental costs. Biological pretreatment strategies have the potential to mitigate these expenses by harnessing the innate ability of specialized bacteria and fungi to deconstruct lignocellulose. White-rot fungi (e.g. Trametes versicolor) have been shown to be effective at biological pretreatment of lignocellulose, yet it was uncertain if these fungi are feedstock agnostic or are able to sense subtle changes in cell wall chemistry. Results: The present study examined the transcriptome response by Trametes versicolor to transgenic hybrid poplar (Populus tremula × alba) lines with altered syringyl (S) and guaiacyl (G) lignin. Specifically, the transcriptional response of the fungus to wild-type wood was compared to that from the wood of six transgenic lines within three lignin phenotypes, LSX (low S with hydroxy-G), LSHG (low S with high G), and HS (high S), with 350 transcripts showing significant differences among the samples. The transcriptome of T. versicolor varied according to the lignin phenotype of the wood, with the LSX wood resulting in the most substantial changes in T. versicolor transcript abundance. Specifically, the LSX wood led to 50 upregulated and 48 downregulated transcripts from WT at the 2-fold or greater threshold. For example, transcripts for the lignin peroxidases LiP3 and LiP10 were downregulated (approximately 12X and 31X lower, respectively) by the fungus on LSX wood compared to wild-type wood. LSX wood also resulted in approximately 11X lower transcript numbers of endo-β-1,4-glucanase yet led to an increase in expression of certain hemicellulases, further highlighting the altered deconstruction strategy by the fungus on this wood type. Conclusions: Overall, the results of this study demonstrated that T. versicolor was able to respond to transgenic poplar wood with the same genetic background, which has important implications for biological pretreatment strategies involving feedstocks that are genetically modified or have considerable natural variations in cell wall chemistry.

Project description:We investigated the transcriptional response of cand. Pelagibacter ubique cultures to light and dark when grown under carbon replete and deplete conditions. Results: During exponential phase, few genes were differentially transcribed between light:dark growth conditions. In stationary phase, a high proportion (9.7%) of coding sequences were found differentially expressed between treatments; 4.7% being up-regulated in the light (n=64) and 4.9% being up-regulated in the dark (n=67). Several components of the oxidative phosphorylation pathway were up-regulated in the dark, supporting physiological data showing higher respiration rates in darkness than in the light under starvation conditions. We also observed up-regulation of a proton translocating pyrophosphate synthase (SAR11_1040), which may be an additional energy production mechanism utilized by SAR11 cells in the dark. Finally, we noted the up-regulation of pili formation genes in the array data, consistent with the observation of pili in dark grown cells via electron microscopy.
