Gossypium longicalyx (F1) genome NSF_v1
About the assembly
We report a de novo genome assembly for G. longicalyx germplasm name 'F1-1'. This genome was first assembled from ~144x coverage (raw) of PacBio reads, which alone produced an assembly consisting of 229 contigs with an N50 of 28.8 MB (Table1). The contigs were scaffolded using a combination of Chicago Highrise, Hi-C, and BioNano to produce a chromosome level assembly consisting of 17 contigs with an average length of 70.4 Mb (containing only 8.4 kb of gap sequence). Thirteen of the chromosomes were assembled into single contigs. Exact placement sequences were included in NCBI with the assembled chromosomes. The final genome assembly size was 1190.7 MB, representing over 90% of the estimated genome size (Hendrix and Stewart 2005)
** Genome size for G. longicalyx is 1311 (Hendrix and Stewart, 2005)

Additional information about this analysis:
All annotation files are available for download by selecting the desired data type in the left-hand "Resources" side bar. Each data type page will provide a description of the available files and links do download. Alternatively, you can use the CottonGen data repository for bulk download.
Functional annotation files for the Gossypium longicalyx NSF Genome v1.0 are available for download below. The Gossypium longicalyx HGS Genome proteins were analyzed using InterProScan in order to assign InterPro domains and Gene Ontology (GO) terms. Pathways analysis was performed using the KEGG Automatic Annotation Server (KAAS).

Homology of the Gossypium longicalyx NSF 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 longicalyx genome 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. longicalyx genome assembly. Alignments with an alignment length of 97% and 90% identify were preserved. The available files are in GFF3 format.
