We have already discussed in a previous post two possible models of cellular metabolism that can account for oil accumulation and that are in agreement with the profile of transcript and protein abundance in Nannochloropsis‘ cultures that accumulate lipids. New experimental data became recently available for the scientific community concerning this issue. Jing Li and coworkers performed a time course experiment, tracking simultaneously transcript abundance and lipid content of Nannochloropsis cultures grown in N sufficient (+N) and N depleted (-N) media. The data and their analysis were published on Plant Cell (doi: http://dx.doi.org/10.1105/tpc.113.121418). Full reference is reported at the end of this post (reference n 1).
After manual review by the NCBI experts, the genomic data of Nannochloropsis gaditana B-31 are now indexed in the NCBI databases and are accessible through the NCBI web interface and through the NCBI search tools (e.g. blast).
The genomes of the nucleus and of the organelles and the complete annotation of the genomic sequences are registered as bioproject PRJNA170989 ID: 170989, and can be accessed through the following links:
The sequencing data used to assembly of the genomes were also submitted to the NCBI SRA database and are available for consulting and download. You can find the data of: a fragment library of Nannochloropsis gaditana B-31 whole genomic DNA (i.e. includes DNA from the nucleus and from the organelles) sequenced using 454FLX Titanium XL sequencing kit, 2 half plates (http://www.ncbi.nlm.nih.gov/sra/SRX390591); a mate pair library of Nannochloropsis gaditana B-31 whole genomic DNA with an insert size of 1.5-3Kb sequenced using the SOLiD 3 Plus sequencing kit, half plate (http://www.ncbi.nlm.nih.gov/sra/SRX390674); a mate pair library of Nannochloropsis gaditana B-31 whole genomic DNA with an insert size of 3-5Kb sequenced using the SOLiD 3 Plus sequencing kit, half plate (http://www.ncbi.nlm.nih.gov/sra/SRX390681).
