Copper River Delta - Impact of Nutrient Limitation

ABSTRACT: Our study objectives were to investigate both the nutrient limitation status of these ponds using nutrient diffusing substrate experiments and to examine how pond biofilm communities were affected by nutrient amendments using targeted high-throughput gene amplicon sequencing.

Climate sensitivity of Equatorial Pacific nutrient limitation

Project description:Projected responses of ocean net primary productivity (NPP) to climate change are highly uncertain. The climate sensitivity of phytoplankton nutrient limitation in the low-latitude Pacific plays a crucial role, but field measurements are insufficient to provide suitable constraints. Here we quantify two decades of nutrient limitation in the Equatorial Pacific with satellite observations. Using field nutrient addition experiments, proteomics, and above-water hyperspectral radiometry, we demonstrate that physiological responses of phytoplankton to iron limitation led to ~3-fold increases in chlorophyll-normalized phytoplankton fluorescence. Extension to the >18-year satellite fluorescence record showed that Equatorial Pacific iron limitation was robust to changes in physical forcing through multiple El Niño–Southern Oscillation cycles, despite coherent fluctuations in limitation strength. In contrast, these iron limitation changes were overestimated 2-fold by a state-of-the-art climate model. Such synoptic constraints provide a powerful new approach for benchmarking the realism of model NPP projections to climate changes.

Cellular stress response of Sulfolobus acidocaldarius to nutrient limitation

Project description:This study provides novel insights into archaeal stress response. The effect of nutrient limitation on the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius was monitored over time on transcriptomic, proteomic and metabolic level. To our knowledge, this linkage of transcriptome, proteome, metabolome analysis makes this study a pioneer study to elucidate cellular stress response triggered by nutrient limitation. We further connect previously identified pH and salt stress responsive genes (1) with genes regulated in starvation and suggest that they constitute the core of stress responsive genes active under multiple stress sources.

(p)ppGpp-dependent activation of gene expression during nutrient limitation

Project description:As rapidly growing bacteria begin to exhaust nutrients, their growth rate slows, ultimately leading to stasis or quiescence. Adaptation to nutrient limitation requires widespread metabolic remodeling that leads to lower cellular energy consumption. Examples of such changes include attenuated transcription of genes encoding ribosome components, in part mediated by the phosphorylated nucleotides guanosine tetra- and penta-phosphate, collectively (p)ppGpp. In addition, genes such as those encoding specific proteins that facilitate survival exhibit increased expression during nutrient limitation. An example is the hpf gene, encoding a broadly conserved protein responsible for protecting the ribosome from degradation under conditions limiting for ribosome synthesis. Here we show that (p)ppGpp plays a key role in the transcriptional activation of hpf as B. subtilis cells exit rapid growth. Specifically, we demonstrate that hpf transcription during nutrient limitation requires an RNAP holoenzyme containing the alternative sigma factor σH, encoded by sigH, whose expression is normally inhibited by the AbrB repressor. However, when global protein synthesis decreases, in part dependent on (p)ppGpp, AbrB levels fall, leading to increased sigH transcription and consequently hpf activation. This mechanism couples a key physiological consequence of nutrient limitation – reduced protein synthesis – with specific gene activation, thereby linking transcriptional and translational regulation. Finally, we demonstrate that (p)ppGpp is necessary for the gene expression underlying the elaboration of developmental fates including sporulation and genetic competence. Thus, the active attenuation of protein synthesis by (p)ppGpp is not only necessary for the conservation of energetic resources but also for the proper pattern of gene activation during transition to quiescence.
