Project description:Here we present the assembled genome of the facultative methanotroph, Methylocystis strain SB2, along with assessment of its transcriptome when grown on methane vs. ethanol. As expected, transcriptomic analyses indicate methane is converted to carbon dioxide via the canonical methane oxidation pathway for energy generation, and that carbon is assimilated at the level of formaldehyde via the serine cycle. When grown on ethanol, it appears this strain converts ethanol to acetyl-CoA and then utilizes the TCA cycle for energy generation and the ethylmalonyl CoA pathway for the production of biomass.

All cultures were grown in triplicates for subsequent DNA and RNA extraction as well as for subsequent sequencing using Illumina. Transcriptomic analysis results presented in this Series.

Project description:Ruminant livestock are one of the major contributors to carbon emission contributing the global warming issue. Methane (CH4) produced from enteric microbial fermentation of feed in the reticulo-rumen are known to differ between sheep with different digestive function and fermentation products such as metabolites. However, the molecular mechanism underpinning differences in methane emission remains to be fully elucidated. We extracted a membrane and cytosolic protein fraction of rumen epithelium proteins from both high (H) and low (L) CH4 emitting sheep. Protein abundance differences between the phenotypes were quantified using SWATH-mass spectrometry. We identified 92 proteins annotated as cell surface transporters, of which only solute carrier family (SLC) 40A1 had a greater fold change of protein expression in the high methane emission phenotype. The main difference in protein abundance we found were related to the metabolism of glucose, lactate and processes of cell defence against microbes in the epithelium of sheep in each group. To best of our knowledge, this represents one of the most comprehensive proteomes of ovine rumen epithelium to date.

Project description:The C4 pathway is a highly complex trait that increases photosynthetic efficiency in over sixty plant lineages. Although the majority of C4 plants occupy disturbed, arid and nutrient-poor habitats, some grow in high-nutrient, waterlogged conditions. One such example is Echinochloa glabrescens, which is an aggressive weed of rice paddies. We generated comprehensive transcriptome datasets for C4 E. glabrescens and C3 rice to identify genes associated with adaption to waterlogged, nutrient-replete conditions, but also used the data to better understand how C4 photosynthesis operates in these conditions. Similar to arid C4 species, leaves of E. glabrescens exhibited classical Kranz anatomy with lightly lobed mesophyll cells. As with rice and other hygrophytic C3 species, leaves of E. glabrescens accumulated a chloroplastic phosphoenolpyruvate carboxylase protein, albeit at reduced levels relative to rice. We identified a molecular signature associated with C4 photosynthesis in nutrient-replete, waterlogged conditions that is highly similar to those previously reported from C4 plants that grow in more arid conditions. We also identified a cohort of genes that have been subjected to a selective sweep associated with growth in paddy conditions. Overall, this approach highlights the value of using wild species such as weeds to identify adaptions to specific conditions associated with high-yielding crops in agriculture.
