Abstract
Cultivated strawberry (Fragaria × ananassa, 2n = 8x = 56) is an important horticultural crop with substantial economic and nutritional value. The improvement of cultivated strawberry is more challenging not only in its octoploid genome but also in the frequent homoeologous exchanges and polyploidization, which replaces substantial portions of some subgenomes with sequences derived from ancestrally related chromosomes (Edger et al., 2019). Therefore, a high-quality genome for the cultivated strawberry will provide important information for identifying agriculturally important genes for breeding. Several cultivated strawberry genomes have been assembled. However, some published reference genomes of cultivated strawberries remained incomplete, and some published genomes of cultivated strawberries were not truly haplotype-resolved (Edger et al., 2019; Lee et al., 2021; Mao et al., 2023; Song et al., 2024). Here, we de novo assembled a telomere-to-telomere haplotype-resolved reference genome with 56 chromosomes (Figure 1a) of the white-fruited strawberry cultivar ‘Chulian’ (Figure S1) by incorporating PacBio HiFi, ONT ultra-long and Hi-C sequencing, and Illumina sequencing data. The centromere candidate sequences and regions of each chromosome were identified (Figure S2 and Table S1). We divided 56 chromosomes into two haplotypes, Hap1 (chr × − × −1) and Hap2 (chr × − × −2), and each haplotype includes 28 chromosomes. The final genome assembly sizes were 787.52 Mb with 33 contigs for Hap1 and 778.03 Mb with 34 contigs for Hap2, respectively. The contigs N50 of Hap1 and Hap2 were 27.92 Mb and 26.45 Mb, respectively. We identified 52 telomeres in Hap1 and 50 in Hap2 by investigating telomeric repeats (TTTAGGG)n (Figures S2; Table S2). The integrity and accuracy of the genome assembly of ‘Chulian’ were evaluated by Benchmarking Universal Single-Copy Orthologs (BUSCO) assessments (Tables S3 and S4) and showed that the genome assembly of ‘Chulian’ had high coverage and quality. A total of 110 001 and 108 859 protein-coding genes were annotated in the Hap1 and Hap2, respectively. In addition, 5864 and 5830 transcription factors were predicted in the Hap1 and Hap2, respectively. The information on repetitive sequences is in Tables S5 and S6. We conducted collinearity analysis of Hap1 (Reference) and Hap2 (Query) to investigate variations of two haplotype genomes of ‘Chulian’ strawberry. We discovered 16 315 syntenic blocks totaling ~631 Mb, covering 92.82% and 93.96% of the Hap1 and Hap2 genomes (Figure S3; Table S7). Moreover, we compared ‘Chulian’ with the high-quality cultivated strawberry ‘Yanli’ (Mao et al., 2023) due to their diverse phenotype differences, such as fruit colour, hardness and powdery mildew resistance. The comparison results showed that the haplotype genome of ‘Chulian’ and ‘Yanli’ had high similarity and collinearity (Figure S4). We compared Hap1 and Hap2 of ‘Chulian’ to Hap1 and Hap2 of ‘Yanli’ to analyse the number of structural variations (SVs), the length range of SVs and the position of the maximum SVs per chromosome (Figure S5). The SVs with lengths over 100 bp and located in the genomic gene regions (exons and introns), promoter region (2 kb from start codon) and downstream regions (2 kb from stop codon) between ‘Chulian’ and ‘Yanli’ had also been completely identified (Appendix S1). Interestingly, many genes of ‘Chulian’ with large SVs in their exon and promoter regions were related to disease resistance, including receptor protein kinase containing LRR repeats, TIR-NBS-LRR class protein, chitinase and putative powdery mildew resistance protein compared with ‘Yanli’ (Appendix S2). Moreover, we also found numerous transcription factors (WRKY, MYB, MADS-box, bHLH, ERF, bZIP, etc.) of ‘Chulian’ with large SVs in these exon and promoter regions compared with ‘Yanli’ (Appendix S2), and the functions of these transcription factors need to be investigated in further. The fruit flesh of ‘Chulian’ was white due to the loss of anthocyanin accumulation. To identify candidate genes responsible for the white fruit phenotype of ‘Chulian’, we examined the master positive regulator FaMYB10 of anthocyanin biosynthesis in ‘Chulian’ and ‘Yanli’ by utilizing the high-quality genomic sequence. Interestingly, the FaMYB10 on chr1-2-1 had 8-bp ‘ACTTATAC’ insertion in the 491 nucleotides of ‘Chulian’ (Figure S6a). The FaMYB10 on chr1-2-1 of ‘Chulian’ germinated a truncated protein with 179 amino acids due to a premature stop codon relative to ‘Yanli’ (producing 233 amino acids; Figure S6b). The FaMYB10 on chr1-2-2 only had a single nucleotide difference compared with ‘Yanli’. The point mutation (C to A) was found at the 94th nucleotide, resulting in an amino acid substitution from histidine (H) in ‘Yanli’ to asparagine (N) in ‘Chulian’ (Figures S1a, b). The transient functional analysis found that overexpression of FaMYB10 on chr1-2-1 of ‘Yanli’ could restore the anthocyanin deficiency phenotype of ‘Chulian’ (Figure S7). Interestingly, the transient functional analysis found that the fruits of importing FaMYB10 on chr1-2-2 of ‘Chulian’ with its promoter [Pro-CL-FaMYB10(1–2-2)] did not restore the anthocyanin deficiency phenotype of ‘Chulian’. In contrast, the fruits of importing FaMYB10 on chr1-2-2 of ‘Yanli’ with its promoter [Pro-YL-FaMYB10(1–2-2)] recovered the anthocyanin deficiency phenotype of ‘Chulian’ (Figure 1b). Furthermore, some anthocyanin biosynthetic genes' expression levels increased in the fruits of importing Pro-YL-FaMYB10(1–2-2) compared with the control fruit (Figure S8). These results suggested that the point mutation of FaMYB10 on chr1-2-2 of ‘Chulian’ affected its function, and the molecular basis awaits further investigation. Together, 8-bp insertion in FaMYB10 on chr1-2-1 and the point mutation in FaMYB10 on chr1-2-2 were the main reasons for the white fruit phenotype of the ‘Chulian’ strawberry. Cultivated strawberry is an allo-octoploid species with four subgenomes (Edger et al., 2019). Genes from different subgenomes display expression differences, and the dominant gene expression pattern is detected in many allopolyploid species. During the development of ‘Chulian’ strawberry fruits, FaMYB10 on chr1-2 was the dominant expression gene (Figure S9). However, the fruit skin of ‘Chulian’ turned red and accumulated anthocyanin under light treatment (Figure 1c). We conducted RNA-seq of fruit skin of ripening fruits under lighting and shading treatments. A total of 5265 genes were differentially expressed. 2215 were upregulated, and 3050 were downregulated (Figure S10a). KEGG analysis revealed these differentially expressed genes mainly involved in plant hormone signal transduction, plant circadian rhythm, protein processing in the endoplasmic reticulum and flavonoid metabolism pathways (Figure S10b). Intriguingly, we found the transcript level of FaMYB10 on chr1-4 of ‘Chulian’ other than FaMYB10 on chr1-2 in the fruit skin under lighting treatment was significantly increased compared with fruit skin under shading treatment (Figure 1d). Moreover, we found the promoter of FaMYB10 on chr1-4 included more light-responsive elements and salicylic acid and methyl jasmonate elements (Figure S11; Table S8) than FaMYB10 on chr1-2 of ‘Chulian’. In conclusion, we obtained a high-quality haplotype-resolved genome of the octoploid white-fruited cultivar ‘Chulian’. We found that an 8-bp insertion in the coding region of FaMYB10 on chr1-2-1 and the single nucleotide mutation in FaMYB10 on chr1-2-2 were related to the loss of anthocyanins in the fruits. Interestingly, we found that the accumulation of anthocyanins was light-regulated by activating the expression of FaMYB10 on chr1-4 instead of the dominant homoeologous FaMYB10 on chr1-2 during fruit development. These results will lay a solid foundation for comparative genomic analysis, understanding the expression pattern of genes in the subgenome of polyploidy species and fruit colour breeding of cultivated strawberry.
