The role of the LysR-type transcription factor PacR in regulating nitrogen metabolism in Anabaena sp. PCC7120

Project description:Deletion of the global transcription factor PacR in Anabaena triggers heterocyst formation even in NO3- containing medium, likely due to impaired NO3- uptake and disrupted NH4+ assimilation in the GOGAT cycle. This phenotype may be exacerbated by reduced PSI-yield and reduced expression of ferredoxin, which may lead to less reducing equivalents for nitrogen uptake and fixation. These results highlight PacR’s role as a global regulator of carbon metabolism and photosynthesis while also establishing its involvement in regulating nitrogen metabolism.

Unbalancing FurB (Zur)-mediated homeostasis in Anabaena sp. PCC7120: Consequences on heterocyst development and biofilm formation

Project description:Here, we report the comparison of transcriptomes of Anabaena sp. PCC7120 and the FurB(Zur) deletion derivative strain (MN38). Anabaena sp PCC7120 is a cyanobacterium that differentiates specialized nitrogen-fixing cells called heterocysts and that is capable of forming biofilms. Our data showed that the deletion of FurB negativily affected the heterocyst development and the biofilm formation. In addition, the RNA-seq data together with gel retardation assays unveiled that FurB is directly involved in the regulation of several genes related to heterocyst development and biofilm formation and other novel functions different from the ones related to the canonical Zur regulon.

Anabaena PCC7120 infection with Cyanophage A1

Project description:In order to examine the response of Anabaena sp. PCC 7120 to an infection of the Cyanophage A1, we have used customized microarrays to identify genes potentially up- or downregulated by the infection. For this we compared cell culture before and after infection.

RNA-seq of Nostoc sp. PCC 7120 (Anabaena sp. PCC 7120) wild-type strain compared to a FurC-overexpressing derivative strain grown in BG11 and after 48 hours of nitrogen-step down.

Project description:Here, we report the comparison of transcriptomes of Anabaena sp. PCC7120 and a FurC-overexpressing derivative strain grown under standard conditions (BG11) and after 48 hours of nitrogen step-down (BG110). Anabaena sp PCC7120 is a cyanobacterium that differentiates specialized nitrogen-fixing cells called heterocysts. Our data suggests that FurC directly controls the regulation of heterocyst differentiation and nitrogen fixation in this cyanobacterium. In addition, we found that FurC is also clearly involved in the regulation of several genes belonging to different functional categories, such as iron metabolism, photosynthesis and regulatory functions.

Deletion and Complementation of Alr3614 in Anabaena PCC7120

Project description:To examine Alr3614 influence on the expression of Anabaena sp. PCC 7120, we have used customized microarrays to identify genes potentially regulated by this short DNA-binding protein. We compared the expression of an Alr3614-deletion strain with an Alr3614-complementation strain.

Transcriptional Regulation of Anabaena 7120 response to Nitrogen Deprivation

Project description:Here, we report the transcriptome of Anabaena sp. strain 7120, a cyanobacterium that forms specialized nitrogen-fixing cells called heterocysts. Our data suggests that cyanobacteria frequently have more complex transcripts than thought, with large 5' UTRs, numerous antisense transcripts, and multiple transcriptional start sites or processing sites.

Improved eco-friendly recombinant Anabaena sp. strain PCC7120 with enhanced nitrogen biofertilizer potential.

Project description:Photosynthetic, nitrogen-fixing Anabaena strains are native to tropical paddy fields and contribute to the carbon and nitrogen economy of such soils. Genetic engineering was employed to improve the nitrogen biofertilizer potential of Anabaena sp. strain PCC7120. Constitutive enhanced expression of an additional integrated copy of the hetR gene from a light-inducible promoter elevated HetR protein expression and enhanced functional heterocyst frequency in the recombinant strain. The recombinant strain displayed consistently higher nitrogenase activity than the wild-type strain and appeared to be in homeostasis with compatible modulation of photosynthesis and respiration. The enhanced combined nitrogen availability from the recombinant strain positively catered to the nitrogen demand of rice seedlings in short-term hydroponic experiments and supported better growth. The engineered strain is stable, eco-friendly, and useful for environmental application as nitrogen biofertilizer in paddy fields.
