Monoraphidium neglectum (original) (raw)
Monoraphidium neglectum is a single-cell green alga of the family Selenastraceae. There is interest in using M. neglectum for the production of biofuels because it can accumulate large quantities (up to 33 % of cell dry weight) of triacylglycerides (TAGs).

| dbo:abstract | Monoraphidium neglectum is a single-cell green alga of the family Selenastraceae. There is interest in using M. neglectum for the production of biofuels because it can accumulate large quantities (up to 33 % of cell dry weight) of triacylglycerides (TAGs). In 2013, a draft nuclear, mitochondrial, and chloroplast genome was published with an estimated nuclear size of 68 Mb and approximately 16,761 genes. The nuclear genome is likely diploid. The mitochondrial genome of M. neglectum is 96 kb, which is twice as large as and nearly six times larger than the green alga Chlamydomonas reinhardtii, but contains fewer genes. A nuclear transformation technique has been established for M. neglectum using electrotransformation as the method of DNA delivery. The strategy described in this study, including a pretreatment step to weaken the cell wall, might inspire future studies with other microalgae also aiming at stable nuclear genetic transformation using electrotransformation. The transcriptome of M. neglectum has been sequenced using Illumina HiSeq technology. Using a poly-A fishing and genome-guided approach, the transcriptome was assembled into 20,751 genes (i. e., loci). The dataset encompasses a time-course experiment under conditions of both, high TAG accumulation and subsequent TAG degradation. TAG accumulation and degradation were induced by nitrogen removal (-N conditions) and nitrogen resupply (NR conditions). In total, the transcriptome was sequenced at 12 time points (t0, 7x -N, 4x NR), yielding a comprehensive and high-quality dataset. The raw data (100 nt paired-end reads) has been deposited at SRA under the SRA Study accession number SRP112537. The processed data is available at http://tdbmn.cebitec.uni-bielefeld.de, at which direct gene and BLAST search enable for data mining and to investigate the expression patterns of target genes under autotrophic -N and NR conditions. It is furthermore possible to compare the expression patterns of target genes of M. neglectum with those of other microalgae which were also subjected to -N conditions to induce TAG accumulation.
