Polystyrene microplastics increase microbial release of marine Chromophoric Dissolved Organic Matter in microcosm experiments.

Project description:About 5 trillion plastic particles are present in our oceans, from the macro to the micro size. Like any other aquatic particulate, plastics and microplastics can create a micro-environment, within which microbial and chemical conditions differ significantly from the surrounding water. Despite the high and increasing abundance of microplastics in the ocean, their influence on the transformation and composition of marine organic matter is largely unknown. Chromophoric dissolved organic matter (CDOM) is the photo-reactive fraction of the marine dissolved organic matter (DOM) pool. Changes in CDOM quality and quantity have impacts on marine microbial dynamics and the underwater light environment. One major source of CDOM is produced by marine bacteria through their alteration of pre-existing DOM substrates. In a series of microcosm experiments in controlled marine conditions, we explored the impact of microplastics on the quality and quantity of microbial CDOM. In the presence of microplastics we observed an increased production of CDOM with changes in its molecular weight, which resulted from either an increased microbial CDOM production or an enhanced transformation of DOM from lower to higher molecular weight CDOM. Our results point to the possibility that marine microplastics act as localized hot spots for microbial activity, with the potential to influence marine carbon dynamics.

Crustacean zooplankton release copious amounts of dissolved organic matter as taurine in the ocean.

Project description:Taurine (Tau), an amino acid-like compound, is present in almost all marine metazoans including crustacean zooplankton. It plays an important physiological role in these organisms and is released into the ambient water throughout their life cycle. However, limited information is available on the release rates by marine organisms, the concentrations and turnover of Tau in the ocean. We determined dissolved free Tau concentrations throughout the water column and its release by abundant crustacean mesozooplankton at two open ocean sites (Gulf of Alaska and North Atlantic). At both locations, the concentrations of dissolved free Tau were in the low nM range (up to 15.7 nM) in epipelagic waters, declining sharply in the mesopelagic to about 0.2 nM and remaining fairly stable throughout the bathypelagic waters. Pacific amphipod-copepod assemblages exhibited lower dissolved free Tau release rates per unit biomass (0.8 ± 0.4 μmol g-1 C-biomass h-1) than Atlantic copepods (ranging between 1.3 ± 0.4 μmol g-1 C-biomass h-1 and 9.5 ± 2.1 μmol g-1 C-biomass h-1), in agreement with the well-documented inverse relationship between biomass-normalized excretion rates and body size. Our results indicate that crustacean zooplankton might contribute significantly to the dissolved organic matter flux in marine ecosystems via dissolved free Tau release. Based on the release rates and assuming steady state dissolved free Tau concentrations, turnover times of dissolved free Tau range from 0.05 d to 2.3 d in the upper water column and are therefore similar to those of dissolved free amino acids. This rapid turnover indicates that dissolved free Tau is efficiently consumed in oceanic waters, most likely by heterotrophic bacteria.

Medicago truncatula drought stress recovery

Project description:Molecular Elasticity and Adjustment of Drought Recovery Dynamics of 14N- and 15N-fertilized Legume Medicago truncatula. Climate change in conjunction with population growth necessitates a systems biology approach to characterize plant drought response and a more thorough understanding of the underlying molecular mechanisms. During drought stress and recovery, the metabolome and proteome regulate and are regulated through diverse mechanisms including synthesis and degradation. In order to study this complex regulation network, a front-end multilevel analysis is presented for the first time, investigating protein turnover, regulatory classes of proteins and metabolites as well as post translational ubiquitination of a target set of proteins during a severe stress and recovery scenario in the model legume Medicago truncatula. Evidence for enhanced translational proteome regulation was observed during drought recovery and functional clusters of differentially dynamic phases during the course of recovery were defined. The data give novel insights into molecular elasticity that enable recovery of drought stressed plants. Additionally, these results offer putative targets and metabolic pathways for future plant-bioengineering towards enhanced drought stress tolerance.
