Project description:The aims of our study were: 1) to elucidate physiological responses in three Miscanthus species and newly bred triploid hybrid in three water stress treatment conditions 2) utilise the induced physiological conditions for an in-depth transcriptome study on the molecular basis of water stress in Miscanthus spp.

Project description:The sterile hybrid grass Miscanthus x giganteus (Mxg) can produce more than 30 t dry matter/ha/year. This biomass has a range of uses, including animal bedding and a source of heating fuel. The grass provides a wide range of other ecosystem services (ES), including shelter for crops and livestock, a refuge for beneficial arthropods, reptiles and earthworms and is an ideal cellulosic feedstock for liquid biofuels such as renewable (drop-in) diesel. In this study, the effects of different strains of the beneficial fungus Trichoderma on above- and below-ground biomass of Mxg were evaluated in glasshouse and field experiments, the latter on a commercial dairy farm over two years. Other ES benefits of Trichoderma measured in this study included enhanced leaf chlorophyll content as well as increased digestibility of the dried material for livestock. This study shows, for the first time for a biofuel feedstock plant, how Trichoderma can enhance productivity of such plants and complements other recent work on the wide-ranging provision of ES by this plant species.

Project description:Adult male grass shrimp were exposed for 96 hours to LC50 concentrations of either Fipronil, Endosulfan, or Cadmium, as well as a Carrier Control exposure. RNA was extracted from whole-body homogenates using the RNABee kit. Tags were clustered to identify tags diagnostic of the different exposures. Keywords: SAGE, Grass shrimp, ecotoxicogenomics

Project description:Small RNAs (21-24 nt) are pivotal regulators of gene expression that guide both transcriptional and post-transcriptional silencing mechanisms in diverse eukaryotes, including most if not all plants. MicroRNAs (miRNAs) and short interfering RNAs (siRNAs) are the two major types, both of which have a demonstrated and important role in plant development, stress responses and pathogen resistance. In this work, we used a deep sequencing approach (Sequencing-By-Synthesis, or SBS) to develop sequence resources of small RNAs from different Miscanthus x giganteus tissues (including leaves, flowers, and rhizomes). The high depth of the resulting datasets enabled us to examine in detail critical small RNA features such as size distribution, tissue-specific regulation and sequence conservation between different organs in this species. We also developed database resources and a dedicated website (http://smallrna.udel.edu/) with computational tools for allowing other users to identify new miRNAs or siRNAs involved in specific regulatory pathways, verify the degree of conservation of these sequences in other plant species and map small RNAs on genes or larger regions of the genome under study.

Project description:This study explored the transcriptomic response of couch grass rhizome meristhematic region exposed to mild, medium and severe drought. The couch grass stress response was compared with the response of two contrasting barley cultivars and the specificities and commonalities in transcriptomic stress response of both species were identified.

Small RNA libraries were derived from leaves, flowers and rhizomes of Miscanthus x giganteus. Each tissue represented a mixture of developmental stages, with a bias towards those from early, actively differentiating cells. For rhizomes, the apical tip portion was collected. Total RNA was isolated using the Plant RNA Purification Reagent (Invitrogen) and submitted to Illumina (Hayward, CA, http://www.illumina.com) for small RNA library construction using approaches described in (Lu et al., 2007) with minor modifications. The small RNA libraries were sequenced with the Sequencing-By-Synthesis (SBS) technology by Illumina. PERL scripts were designed to remove the adapter sequences and determine the abundance of each distinct small RNA. We thank Steven Moose for providing the plant material and Kan Nobuta for assistance with the computational methods.
