Gossypium thurberi (D1-5) genome CRI_v1
About the assembly
The Gossypium thurberi 'D1-5' was obtained from the National Wild Cotton Nursery China and its DNA was extracted from 180 young leave collected from greenhouse in Sanya, China.
We assembled the genomes of G. thurberi and G. davidsonii using data from both the nanopore long-read and the Hi-C short-read technologies. We produced 114.3 Gb and 108.3 Gb clean reads, respectively, for G. thurberi (~ 146×) and G. davidsonii (~ 135×) using the Nanopore platform (publication: Additional file 1: Table S1-S2). After correction using the Illumina short reads, we generated a G. thurberi genome of 779.6 Mb with a contig N50 of 24.7 Mb; the corresponding values for G. davidsonii were 801.2 Mb and 26.8 Mb (publication: Table 1 and Additional file 1: Table S3); the sequence continuities are significantly improved for both species as compared with other recently reported genome assemblies.

The predicted gene model, their alignments and proteins for Gossypium thurberi '(D1-5)' genome. These files belong to the CRI Assembly v1.0
Homology of the Gossypium thurberi CRI Genome v1.0 proteins was determined by pairwise sequence comparison using the blastp algorithm against various protein databases. An expectation value cutoff less than 1e-9 was used for the NCBI nr (Release 2018-05) and 1e-6 for the Arabidoposis proteins (Araport11), UniProtKB/SwissProt (Release 2019-01), and UniProtKB/TrEMBL (Release 2019-01) databases. The best hit reports are available for download in Excel format.
Marker alignments were performed by the CottonGen Team of Main Bioinformatics Lab at WSU. The alignment tool 'BLAT' was used to map marker sequences from CottonGen to the Gossypium thurberi CRI me assembly. Markers required 90% identity over 97% of their length. For SSRs & RFLPs, gap size was restricted to 1000bp or less with less than 2 gaps. For dbSNPs and Indels gap size was restricted to 2bp with less than 2 gaps. The available files are in GFF3 format. Markers available in CottonGen are linked to JBrowse.
Transcript alignments were performed by the CottonGen Team of Main Bioinformatics Lab at WSU. The alignment tool 'BLAT' was used to map transcripts to the G. thurberi genome assembly. Alignments with an alignment length of 97% and 90% identify were preserved. The available files are in GFF3 format.
