Mechanistic Insights into Validoxylamine A 7’-Phosphate Synthesis by VldE Using the Structure of the Entire Product Complex

Creator:: Cavalier, Michael C., Yim, Young-Sun, Asamizu, Shumpei, Neau, David, Almabruk, Khaled H., Mahmud, Taifo, and Lee, Yong-Hwan
Abstract:: The pseudo-glycosyltransferase VldE catalyzes non-glycosidic C-N coupling between an unsaturated cyclitol and a saturated aminocyclitol with the conservation of the stereochemical configuration of the substrates to form validoxylamine A 7'-phosphate, the biosynthetic precursor of the antibiotic validamycin A. To study the molecular basis of its mechanism, the three-dimensional structures of...

Genetic and Functional Diversification of Small RNA Pathways in Plants

Creator:: Xie, Zhixin, Johansen, Lisa K., Gustafan, Adam M., Kasschau, Kristin D., Lellis, Andrew D., Zilberman, Daniel, Jacobsen, Steven E., and Carrington, James C.
Abstract:: Multicellular eukaryotes produce small RNA molecules (approximately 21–24 nucleotides) of two general types, microRNA (miRNA) and short interfering RNA (siRNA). They collectively function as sequence-specific guides to silence or regulate genes, transposons, and viruses and to modify chromatin and genome structure. Formation or activity of small RNAs requires factors belonging...

Abstract:: Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will increase. Our ability to predict the magnitude and geographic pattern of future fire impacts rests on our ability to model...

Performance of Linear and Nonlinear Two-Leaf Light Use Efficiency Models at Different Temporal Scales

Creator:: Wu, Xiaocui, Ju, Weimin, Zhou, Yanlian, He, Mingzhu, Law, Beverly E., Black, T. Andrew, Margolis, Hank A., Cescatti, Alessandro, Gu, Lianhong, Montagnani, Leonardo, Noormets, Asko, Griffis, Timothy J., Pilegaard, Kim, Varlagin, Andrej, Valentini, Riccardo, Blanken, Peter D., Wang, Shaoqiang, Wang, Huimin, Han, Shijie, Yan, Junhua, Li, Yingnian, Zhou, Bingbing, and Liu, Yibo
Abstract:: The reliable simulation of gross primary productivity (GPP) at various spatial and temporal scales is of significance to quantifying the net exchange of carbon between terrestrial ecosystems and the atmosphere. This study aimed to verify the ability of a nonlinear two-leaf model (TL-LUEn), a linear two-leaf model (TL-LUE), and a...

A new instrument to measure plot-scale runoff

Creator:: Stewart, R. D., Liu, Z., Rupp, D. E., Higgins, C. W., and Selker, J. S.
Abstract:: Accurate measurement of the amount and timing of surface runoff at multiple scales is needed to understand fundamental hydrological processes. At the plot scale (i.e., length scales on the order of 1–10 m) current methods for direct measurement of runoff either store the water in a collection vessel, which is...

A genome scale metabolic network for rice and accompanying analysis of tryptophan, auxin and serotonin biosynthesis regulation under biotic stress

Creator:: Dharmawardhana, Palitha, Ren, Liya, Amarasinghe, Vindhya, Monaco, Marcela, Thomason, Jim, Ravenscroft, Dean, McCouch, Susan, Ware, Doreen, and Jaiswal, Pankaj
Abstract:: Background: Functional annotations of large plant genome projects mostly provide information on gene function and gene families based on the presence of protein domains and gene homology, but not necessarily in association with gene expression or metabolic and regulatory networks. These additional annotations are necessary to understand the physiology, development...

BCL11B Regulates Epithelial Proliferation and Asymmetric Development of the Mouse Mandibular Incisor

Creator:: Kyrylkova, Kateryna, Kyryachenko, Sergiy, Biehs, Brian, Klein, Ophir, Kioussi, Chrissa, and Leid, Mark
Abstract:: Mouse incisors grow continuously throughout life with enamel deposition uniquely on the outer, or labial, side of the tooth. Asymmetric enamel deposition is due to the presence of enamel-secreting ameloblasts exclusively within the labial epithelium of the incisor. We have previously shown that mice lacking the transcription factor BCL11B/CTIP2 (BCL11B...
