About the assembly

DNA was extracted from leaves D1-35. Trimmed data were independently assembled for each species via ABySS v2.0.1 (Simpson et al. 2009), using every 5th kmer value from 40 through 100. A single assembly with the highest E-size (Salzberg et al. 2012) was selected for each species and subsequently annotated with MAKER v2.31.6 (Holt and Yandell 2011) using evidence from: 1) the NCBI G. raimondii EST database (Udall et al. 2006), 2) G. raimondii reference genome predicted proteins, as hosted by CottonGen.org (Paterson et al. 2012), and 3) three ab initio gene prediction programs, that is Genemark v4.30 (Borodovsky et al. 2003), SNAP v2013-11-29 (Korf 2004), and Augustus v3.0.3 (Stanke et al. 2006). Both the SNAP and Augustus models were trained using BUSCO v2.0 (Simão et al. 2015). Chromosomer version 0.1.3 (Tamazian et al. 2016), a reference-assisted scaffolder, was used to scaffold the selected assemblies against the gold standard G. raimondii genome. MAKER v2.31.6 (Holt and Yandell 2011) was used to transfer the previous annotations to the Chromosomer-based scaffolds by rerunning MAKER and using the transcripts from the original annotation as evidence. Assemblies are also available under PRJNA488266.

Functional Analysis

Functional annotation files for the Gossypium thurberi ISU Genome v1.0 are available for download below. The Gossypium thurberi ISU 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

Homology of the Gossypium thurberi ISU 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.

Markers
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 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.
