Corchorus capsularis Assembly and Gene Annotation
About Corcorus capsularis
Corcorus capsularis (white jute) is one of the most important sources of natural fibre used for items like rugs, bags, string and baskets, along with Corcorus olitorius, covering ∼80% of global bast fibre production. The genome size is approximately 400 Mb (n = 7).
Whole-genome shotgun sequencing was performed using Roche/454 GS FLX and was assembled using CABOG (version 7) by the Bangladesh Jute Research Institute. A total of 13.69 Gb of sequence data was generated (~30x), consisting of 7.87 Gb of shotgun sequences (~20x), 2.04 Gb of 3-kb paired-end sequences (14x physical coverage), 2.26 Gb of 8-kb paired-end sequences (15x physical coverage), and 1.51 Gb of 20-kb paired-end sequences (11x physical coverage). The resulting assembly was 338 Mb in 6,125 scaffolds with a scaffold N50 of 4.1 Mb. 80% of the assembly was covered with 231 scaffolds (minimum length 120 kb).
A total of 30,096 protein-coding genes were predicted by a combination of de novo, homology and transcriptome-based approaches by the Bangladesh Jute Research Institute.
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.
