Abstract:
BACKGROUND: Synechocystis sp. PCC6803 is a cyanobacterium
considered as a candidate photo-biological production
platform--an attractive cell factory capable of using CO2 and
light as carbon and energy source, respectively. In order to
enable efficient use of metabolic potential of Synechocystis
sp. PCC6803, it is of importance to develop tools for
uncovering stoichiometric and regulatory principles in the
Synechocystis metabolic network. RESULTS: We report the most
comprehensive metabolic model of Synechocystis sp. PCC6803
available, iSyn669, which includes 882 reactions, associated
with 669 genes, and 790 metabolites. The model includes a
detailed biomass equation which encompasses elementary building
blocks that are needed for cell growth, as well as a detailed
stoichiometric representation of photosynthesis. We demonstrate
applicability of iSyn669 for stoichiometric analysis by
simulating three physiologically relevant growth conditions of
Synechocystis sp. PCC6803, and through in silico metabolic
engineering simulations that allowed identification of a set of
gene knock-out candidates towards enhanced succinate
production. Gene essentiality and hydrogen production potential
have also been assessed. Furthermore, iSyn669 was used as a
transcriptomic data integration scaffold and thereby we found
metabolic hot-spots around which gene regulation is dominant
during light-shifting growth regimes. CONCLUSIONS: iSyn669
provides a platform for facilitating the development of
cyanobacteria as microbial cell factories.

Project description:We compared transcriptomic changes, 5'-triphosphorylated (TSS) and 5'-monophosphorylated (PSS) RNA ends of different strains of the cyanobacterium Synechocystis sp. PCC6803. Comparison encompassed wild-type Synechocystis (WT), a strain overexpressing RNase E and RNase HII (rne(WT)) and a strain overexpressing 5’-sensing-deficient RNase E and RNase HII (rne(5p)). Analysis of changing 5'-monophosphorylated ends revealed 5’ sensing depedent processing sites on a transcriptome-wide level.

Project description:Hernandia nymphaeifolia is an endangered mangrove associate with high ecological, ornamental, and medicinal values. Its special combination of glycophytic and halophytic characteristics provides an ideal system for investigating salt-responsive mechanisms that may be easily extended to genetic improvement of crops with high salt tolerance. However, little is known regarding salt-responsive mechanisms in H. nymphaeifolia. In this study, we posed gradient salt treatments on H. nymphaeifolia seedlings and investigated their physiological and transcriptional reprogramming in response to salinity stress. The results revealed that hyper-salinity stress posed more adverse impacts on leaf growth, cell integrity and photosynthetic performance of H. nymphaeifolia seedlings compared to those in growing in fresh water or low salt condition, mirroring its nature as a mangrove associate. Genes associated with osmolarity sensor and regulator, ROS scavenging and ion homeostasis were differentially expressed accordingly to alleviate the destructive effects. Furthermore, our results unraveled some pivotal kinases and proteins that regulate the synergistic expression of salt-responsive genes, which may act a key role in regulating the transcriptional remodeling upon salinity stress. These findings enrich our knowledge on the molecular mechanisms underlying the phenotypic plasticity of mangrove associates, and also provide valuable genetic resources for mangrove’s conservation and potential bioengineering application in agricultural field.

Project description:Like many other organisms, cyanobacteria exhibit rhythmic gene expression with a period length of 24 hours to adapt to daily environmental changes. In the model organism Synechococcus elongatus PCC 7942 the central oscillator consists of three proteins: KaiA, KaiB and KaiC and utilizes the histidine kinase SasA and its response regulator RpaA as output-signaling pathway. Synechocystis sp. PCC 6803 contains two additional homologs of the kaiB and kaiC genes. Here we demonstrate that RpaA interacts with the core oscillator KaiAB1C1 of Synechocystis sp. PCC 6803 via SasA, similar to Synechococcus elongatus PCC 7942. However, interaction with the additional Kai homologs was not detected, suggesting different signal transduction components for the clock homologs. Inactivation of rpaA in Synechocystis sp. PCC 6803, lead to reduced viability of the mutant in light-dark cycles that aggravated under mixotrophic growth conditions. Chemoheterotrophic growth in the dark was abolished completely. In accordance, transcriptomic data revealed that RpaA is involved in the regulation of genes related to CO2‑acclimation and carbon metabolism under diurnal light conditions. Further, our results indicate that RpaA functions in the posttranslational regulation of glycogen metabolism as well, and a potential link between the circadian clock and motility was identified.
