Gossypium thurberi (D1-35) genome ISU_v1

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.
