Project description:Parque Nacional La Campana (PNLC) is recognized worldwide for its flora and fauna, rather than for its microbial richness. Our goal was to characterize the structure and composition of microbial communities (bacteria, archaea and fungi) and their relationship with the plant communities typical of PNLC, such as sclerophyllous forest, xerophytic shrubland, hygrophilous forest and dry sclerophyllous forest, distributed along topoclimatic variables, namely, exposure, elevation and slope. The plant ecosystems, the physical and chemical properties of organic matter and the soil microbial composition were characterized by massive sequencing (iTag-16S rRNA, V4 and ITS1-5F) from the DNA extracted from the soil surface (5 cm, n = 16). A contribution of environmental variables, particularly related to each location, is observed. Proteobacteria (35.43%), Actinobacteria (32.86%), Acidobacteria (10.07%), Ascomycota (76.11%) and Basidiomycota (15.62%) were the dominant phyla. The beta diversity (~80% in its axes) indicates that bacteria and archaea are linked to their plant categories, where the xerophytic shrub stands out with the most particular microbial community. More specifically, Crenarchaeote, Humicola and Mortierella were dominant in the sclerophyllous forest; Chloroflexi, Cyanobacteria and Alternaria in the xerophytic shrubland; Solicoccozyma in the dry sclerophyllous forest; and Cladophialophora in the hygrophilous forest. In conclusion, the structure and composition of the microbial consortia is characteristic of PNLC's vegetation, related to its topoclimatic variables, which suggests a strong association within the soil microbiome.

Project description:We performed a RNA immunoprecipitations experiments using gfp-specific antibodies to precipitate gfp-tagged La proteins from from gfp-La wild type and sumoylation deficient La mutant (K41/200R) cells and found that specific mRNAs are preferentially enriched gfp-La wild type RIPs when compared to sumoylation deficient La mutant (K41/200R) RIPs.

Project description:We recently identified lysine L-lactylation (KL-la) on histones that can be labelled by L-lactate, the end-product of glycolysis. KL-la has two structural isomers, namely N--(carboxyethyl) lysine (Kce) and lysine D-lactylation (KD-la), which can also be caused by metabolites associated with glycolysis. It is unknown if perturbations of glycolysis can lead to dysregulation of KD-la and Kce, in addition to KL-la. Further, current methods have a difficulty to distinguish among these isomers in cellular contexts. To investigate these questions, we first generated specific antibodies against each one of these three modifications. These reagents enable us to distinguish these three isomers. We demonstrated that KL-la, but not KD-la and Kce, is dynamically regulated by glycolysis. KD-la and Kce occur mainly when the major glycolytic pathway is blocked downstream or when the glyoxalase system is incomplete. This result was also independently confirmed by orthogonal HPLC-mass spectrometry, showing that KL-la is the predominant isomer of lactylation on cellular histones. Finally, we demonstrated that lactyl-CoA, an intermediate between L-lactate and lactylation, is dynamically regulated by glycolysis and is positively correlated with KL-la. Thus, our study clearly shows that KL-la, but not KD-la and Kce, is the major glycolytic- and the Warburg-effect associated responsive modification in cells.

Project description:In this study we investigated the steady-state growth of Methylotuvimicrobium alcaliphilum 20ZR in media containing calcium (Ca) or lanthanum (La, a REE element). RNA-seq profiling of Methylomicrobium alcaliphilum strain 20ZR in bioreactor on methane. Sample cultures, La-optimum, La-CH4 limited, Ca-optimum and Ca-CH4 limited, were collected and immediately transferred into tubes containing 5 ml of the stop solution (5% water-equilibrated phenol in ethanol). It was found, that cells supplemented with La show a higher growth rate compared to Ca-cultures; however, the efficiency of carbon conversion, estimated as biomass yield, is higher in cells grown with Ca. The study was financially supported by DOE under FOA DE-FOA-0001085 and by NSF-CBET award 1605031
