Picocyanobacteria And Deep-Ocean Fluorescent Dissolved Organic Matter Share Similar Optical Properties, Zhao Zhao, Michael Gonsior, Jenna L. Luek, Stephen Timko, Hope Ianiri, Norbert Hertkorn, Philippe Schmitt-Kopplin, Xiaoting Fang, Qinglu Zeng, Nianzhi Jiao, Feng Chen May 2017

Picocyanobacteria And Deep-Ocean Fluorescent Dissolved Organic Matter Share Similar Optical Properties, Zhao Zhao, Michael Gonsior, Jenna L. Luek, Stephen Timko, Hope Ianiri, Norbert Hertkorn, Philippe Schmitt-Kopplin, Xiaoting Fang, Qinglu Zeng, Nianzhi Jiao, Feng Chen

Civil & Environmental Engineering

Marine chromophoric dissolved organic matter (CDOM) and its related fluorescent components (FDOM), which are widely distributed but highly photobleached in the surface ocean, are critical in regulating light attenuation in the ocean. However, the origins of marine FDOM are still under investigation. Here we show that cultured picocyanobacteria, Synechococcus and Prochlorococcus, release FDOM that closely match the typical fluorescent signals found in oceanic environments. Picocyanobacterial FDOM also shows comparable apparent fluorescent quantum yields and undergoes similar photo-degradation behaviour when compared with deep-ocean FDOM, further strengthening the similarity between them. Ultrahigh-resolution mass spectrometry (MS) and nuclear magnetic resonance spectroscopy reveal abundant …


Long-Term Carbon And Nitrogen Dynamics At Spruce Revealed Through Stable Isotopes In Peat Profiles, Erik A. Hobbie, Janet Chen, Paul J. Hanson, Colleen M. Iversen, Karis J. Mcfarlane, Nathan R. Thorp, Kirsten S. Hofmockel May 2017

Long-Term Carbon And Nitrogen Dynamics At Spruce Revealed Through Stable Isotopes In Peat Profiles, Erik A. Hobbie, Janet Chen, Paul J. Hanson, Colleen M. Iversen, Karis J. Mcfarlane, Nathan R. Thorp, Kirsten S. Hofmockel

Faculty Publications

Peatlands encode information about past vegetation dynamics, climate, and microbial processes. Here, we used δ15N and δ13C patterns from 16 peat profiles to deduce how the biogeochemistry of the Marcell S1 forested bog in northern Minnesota responded to environmental and vegetation change over the past  ∼ 10000 years. In multiple regression analyses, δ15N and δ13C correlated strongly with depth, plot location, C∕N, %N, and each other. Correlations with %N, %C, C∕N, and the other isotope accounted for 80% of variance for δ15N and 38% of variance for δ13C, reflecting N and C losses. In contrast, correlations with depth and topography …


Ozone And Haze Pollution Weakens Net Primary Productivity In China, Xu Yue, Nadine Unger, Kandice Harper, Xiangao Xia, Hong Liao, Tong Zhu, Jingfeng Xiao, Zhaozhong Feng, Jing Li May 2017

Ozone And Haze Pollution Weakens Net Primary Productivity In China, Xu Yue, Nadine Unger, Kandice Harper, Xiangao Xia, Hong Liao, Tong Zhu, Jingfeng Xiao, Zhaozhong Feng, Jing Li

All Materials

Atmospheric pollutants have both beneficial and detrimental effects on carbon uptake by land ecosystems. Surface ozone (O3) damages leaf photosynthesis by oxidizing plant cells, while aerosols promote carbon uptake by increasing diffuse radiation and exert additional influences through concomitant perturbations to meteorology and hydrology. China is currently the world’s largest emitter of both carbon dioxide and short-lived air pollutants. The land ecosystems of China are estimated to provide a carbon sink, but it remains unclear whether air pollution acts to inhibit or promote carbon uptake. Here, we employ Earth system modeling and multiple measurement datasets to assess the separate and …

Global Patterns Of Woody Residence Time And Its Influence On Model Simulation Of Aboveground Biomass, Bao-Lin Xue, Qinghua Guo, Tianyu Hu, Jingfeng Xiao, Yuanhe Yang, Guoqiang Wang, Shengli Tao, Yanjun Su, Jin Liu, Xiaoqian Zhao May 2017

Global Patterns Of Woody Residence Time And Its Influence On Model Simulation Of Aboveground Biomass, Bao-Lin Xue, Qinghua Guo, Tianyu Hu, Jingfeng Xiao, Yuanhe Yang, Guoqiang Wang, Shengli Tao, Yanjun Su, Jin Liu, Xiaoqian Zhao

All Materials

Woody residence time (τw) is an important parameter that expresses the balance between mature forest recruitment/growth and mortality. Using field data collected from the literature, this study explored the global forest τw and investigated its influence on model simulations of aboveground biomass (AGB) at a global scale. Specifically, τw was found to be related to forest age, annual temperature, and precipitation at a global scale, but its determinants were different among various plant function types. The estimated global forest τw based on the filed data showed large spatial heterogeneity, which plays an important role in model simulation of AGB by …

The genus Rhizobium contains many species that are able to form nitrogen-fixing nodules on plants of the legume family. Here, we report the 5.5-Mb draft genome sequence of the salt-tolerant Rhizobium sp. strain LCM 4573, which has a G+C content of 61.2% and 5,356 candidate protein-encoding genes.

Host-Selected Mutations Converging On A Global Regulator Drive An Adaptive Leap Towards Symbiosis In Bacteria, Molly Sabrina Pankey, Randi L. Foxall, Ian M. Ster, Lauren A. Perry, Brian M. Schuster, Rachel A. Donner, Matthew Coyle, Vaughn S. Cooper, Cheryl A. Whistler Apr 2017

New Hampshire Agricultural Experiment Station Publications

Host immune and physical barriers protect against pathogens but also impede the establishment of essential symbiotic partnerships. To reveal mechanisms by which beneficial organisms adapt to circumvent host defenses, we experimentally evolved ecologically distinct bioluminescent Vibrio fischeri by colonization and growth within the light organs of the squid Euprymna scolopes. Serial squid passaging of bacteria produced eight distinct mutations in the binK sensor kinase gene, which conferred an exceptional selective advantage that could be demonstrated through both empirical and theoretical analysis. Squid-adaptive binK alleles promoted colonization and immune evasion that were mediated by cell-associated matrices including symbiotic polysaccharide (Syp) and …


Pb2+ Tolerance By Frankia Sp. Strain Ean1pec Involves Surface-Binding, Teal Furnholm, Medhat Rehan, Jessica Wishart, Louis S. Tisa Apr 2017

Pb2+ Tolerance By Frankia Sp. Strain Ean1pec Involves Surface-Binding, Teal Furnholm, Medhat Rehan, Jessica Wishart, Louis S. Tisa

Molecular, Cellular & Biomedical Sciences

Several Frankia strains have been shown to be lead-resistant. The mechanism of lead resistance was investigated for Frankia sp. strain EAN1pec. Analysis of the cultures by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX) and Fourier transforming infrared spectroscopy (FTIR) demonstrated that Frankia sp. strain EAN1pec undergoes surface modifications and binds high quantities of Pb +2 . Both labelled and unlabelled shotgun proteomics approaches were used to determine changes in Frankia sp. strain EAN1pec protein expression in response to lead and zinc. Pb 2+ specifically induced changes in exopolysaccharides, the stringent response, and the phosphate (pho) regulon. Two metal …
