The cluster file for B. napus was generated at AAFC through analysis of 437 genotypes and at TraitGenetics through the analysis of 432 genotypes. The cluster files for B. oleracea and B. rapa were generated with 129 and 121 samples, respectively. In both laboratories, DNA was extracted from young leaf tissue of greenhouse grown plants using a cetyltrimethylammonium bromide (CTAB)-based method (Murray and Thompson 1980 (link)). DNA was quantified and 200 ng were hybridised to the Brassica 60 K Infinium array as described in the manufacturer’s protocol (Illumina Inc., San Diego, CA). The arrays were scanned using an Illumina HiScan or BeadArray Reader, and SNP data were analysed using the Genotyping module of the GenomeStudio software package with the setting for the No Call threshold set to 0.05.

We named the newly annotated gene models following the standards of gene model nomenclature for Brassica reference genomes (http://www.brassica.info/info/genome_annotation.php): Bra (for Brassica rapa) followed by the chromosome number and letter “g” (for gene). Genes from the top to the bottom of chromosomes were assigned numbers (in steps of 10) with five digits with leading zero integers. To distinguish the genes in v3.0 from the other lines of B. rapa, the number “3” (for the third version of B. rapa reference genome) and a single capital letter “C” (for variety Chiifu-401-42) were assigned after a “.” following the gene numbers; for example, BraA05g036760.3C.
After gene prediction, gene functions were assigned according to the best match of the alignments against various protein databases using BLAST v2.2.31 (E-value = 1e-5), including the KEGG33 (link), Swiss-Prot, and TrEMBL databases34 (link). GO terms for each gene were obtained from the corresponding InterPro entries35 (link). Overall, we inferred 44,539 (96.86%) genes that were annotated based on the results from searching the protein databases (Supplementary Table S18).
Intact LTR-RTs were identified using LTR_finder36 (link) and classified the intact LTR-RTs by predicting the RT domains using the Pfam database (version 26.0) and HMMER software37 . Muscle38 (link) was then employed to perform multiple RT sequence alignments, and RAxML39 was adopted to construct maximum likelihood (ML) trees based on the sequence alignments with 500 bootstrap replications. Finally, the interactive tree of life (iTOL)40 (link) was used to plot the ML trees. The analysis of LTR insertion time was performed as previously reported4 (link).
We also performed noncoding RNA annotation for our assembly. tRNA annotation was conducted using tRNAscan-SE (v1.3.1)41 (link) according to its structural characteristics. Homology-based rRNAs were localized by mapping known full-length plant rRNAs to the B. rapa genome v3.0. snRNAs were predicted by Infenal (v1.1)42 (link) using the Rfam database43 . miRNA annotation was performed as previously described44 (link).

We performed comparative analysis of trait-related gene families. Genes from
grape, papaya and Arabidopsis were downloaded from the GenoScope database
( http://www.genoscope.cns.fr/externe/GenomeBrowser/Vitis/), the
Hawaii Papaya Genome Project ( http://asgpb.mhpcc.hawaii.edu/papaya/), and the Arabidopsis
Information Resource ( http://www.arabidopsis.org/). Previously reported
Arabidopsis and Brassica gene sequences were downloaded from
TAIR ( http://www.arabidopsis.org/) and BRAD ( http://brassicadb.org/brad/).
The protein sequences of the genes were used to determine homologues in grape,
papaya, Arabidopsis, B. oleracea and B. rapa by performing
blast comparisons with an E-value 1e–10. The Clustal61 (link) programs were used for multiple sequence alignment. Alignment of
the small family of GI genes was performed using MEGA562 (link) to
conduct neighbour-joining analysis with default parameters and subjected to
careful manual checks to remove highly divergent sequences from further
analysis. While for other genes, often found in families of tens of genes, the
phylogenetic analysis were performed by PhyML63 (link), which can
accommodate quite divergent sequences by implementing a maximal likelihood
approach with initial analysis based on neighbour-joining method. During these
analyses, we constructed trees using both CDS and protein sequence, and the
protein-derived tree was used to show the phylogeny if not much incongruity was
found. Bootstrapping was performed using 100 repetitive samplings for each gene
family. All the inferred trees were displayed using MEGA5 (ref. 62 (link)). The multiple sequence alignment of these families
was provided as Supplementary Data

We took a series of checking and filtering measures on reads following the
Illumina-Pipeline, and low-quality reads, adaptor sequences and duplicates were
removed (Supplementary Methods).
The reads after the above filtering and correction steps were used to perform
assembly including contig construction, scaffold construction and gap filling
using SOAPdenovo1.04 ( http://soap.genomics.org.cn/) (Supplementary Methods). Finally, we used
20-kb-span paired-end data generated from the 454 platform and 105-kb-span
BAC-end data downloaded from NCBI ( http://www.ncbi.nlm.nih.gov/nucgss?term=BOT01) to extend scaffold
length (Supplementary Methods). The
B. oleracea genome size was estimated using the distribution curve of
17-mer frequency (Supplementary
Methods
).
To anchor the assembled scaffolds onto pseudo-chromosomes, we developed a genetic
map using a double haploid population with 165 lines derived from a F1 cross
between two homozygous lines 02–12 (sequenced) and 0188
(re-sequenced). The genetic map contains 1,227 simple sequence repeat markers
and single nucleotide polymorphism markers in nine linkage groups, which span a
total of 1,180.2 cM with an average of 0.96 cM between the
adjacent loci16 (link). To position these markers to the scaffolds,
marker primers were compared with the scaffold sequences using e-PCR (parameters
-n2 -g1 –d 400–800), with the best-scoring match chosen in
case of multiple matches.
We validated the B. oleracea genome assembly by comparing it with the
published physical map constructed using 73,728 BAC clones ( http://lulu.pgml.uga.edu/fpc/WebAGCoL/brassica/WebFPC/)17 (link) and a genetic map from B. napus18 (link) (Supplementary Methods). Eleven
Sanger-sequenced B. oleracea BAC sequences were used to assess the
assembled genome using MUMmer-3.22 ( http://mummer.sourceforge.net/) (Supplementary Methods).

In this study, the genome and protein sequences of the B. rapa (Chiifu-401–42 v3.0), B. oleracea (HDEM), B. nigra (Ni100-LR), B. napus (Darmor-bzh v10) were downloaded from the BRAD database [7 ]; http://brassicadb.cn), B. juncea (SCYZ) genome sequence from NCBI PRJNA615316 [22 ] (https://www.ncbi.nlm.nih.gov/), B. carinata (zd-1) genome sequence from GenBank JAAMPC000000000 [66 ] (https://www.ncbi.nlm.nih.gov/), and the anthocyanin-related genes genome and protein sequences were downloaded from the Arabidopsis database (TAIR; http://www.arabidopsis.org/index.jsp). In order to accurately identify anthocyanin-related genes, we mainly divide it into the following steps: Firstly, local BLASTP has been used to search anthocyanin-related genes with E-value < 1e-20, 55 anthocyanin-related genes protein sequences were derived from Arabidopsis. Secondly, the candidate anthocyanin-related genes in the six Brassica species were identified by a local BLASTN search with 55 anthocyanin-related genes coding sequence from Arabidopsis to identify candidates with E-value < 1e-20, identity > 70%, coverage > 60%. Thirdly, SynOrths software [8 (link)] has been used to determining the collinear orthologous of two genes based on their own sequence similarity and the homology of their flanking genes, and then extracting the colinear genes of anthocyanin-related genes. Finally, the BLASTP, BLASTN and SynOrths software identified results were pooled and deduplicated, and determined in conjunction with PFAM protein family database (https://pfam.xfam.org/).
