Corchorus capsularis Assembly and Gene Annotation
About Corcorus capsularis
Corcorus capsularis (white jute) is one of the most important sources of natural fibre, along with Corcorus olitorius, covering ∼80% of global bast fibre production. The genome size is approximately 400 Mbp (n = 7). The assembly presented here is at the scaffold level, comprising 6,125 scaffolds with a scaffold N50 of 4.1 Mbp.
Whole-genome shotgun sequencing was performed using Roche/454 GS FLX and was assembled using CABOG (version 7). A total of 13.69 Gbp of sequence data was generated (~30x), consisting of 7.87 Gbp of shotgun sequences (~20x), 2.04 Gbp of 3-kbp paired-end sequences (14x physical coverage), 2.26 Gbp of 8-kbp paired-end sequences (15x physical coverage), and 1.51 Gbp of 20-kbp paired-end sequences (11x physical coverage). The resulting assembly was 338 Mbp in 6,125 scaffolds with a scaffold N50 of 4.1 Mbp. Eighty per cent of the assembly was covered with 231 scaffolds (minimum length 120 kbp) and is estimated to cover about 82% of the genome .
More than 97% of the isotigs generated from transcriptome sequencing of seedlings aligned to the genome indicating comprehensive coverage of the gene-rich regions. In addition, more than 97% of the conserved core eukaryotic genes  were present in the genome.
A total of 30,096 protein-coding genes were predicted by a combination of de novo, homology and transcriptome-based approaches .
