Carrot is a biennial herb in the Apiaceae that originated in Afghanistan, and is considered an outstanding source of vitamin A due to its high content of carotenoids. Carotenoids in carrot can provide substrate for vitamins and contribute to preventing cancers, regulating blood sugar levels, fighting oxidation and slowing aging. Telomer-to-telomere genome refers to the high-quality gapless genome obtained by high depth sequencing and assembly of multiple sequencing platforms. The assembly of the T2T genome enables the acquisition of the complete genome of species, which is conducive to the in-depth study of molecular mechanism of character variation. In recent years, the T2T genomes of many horticultural plants have been released, but the complete genome of carrot is not yet available. |

In this study, we assembled a 430.40 Mb high-quality gapless genome to the telomere-to-telomere (T2T) level of ‘Kurodagosun’ carrot. In total, 36,268 genes were identified and 34,961 of them were functionally annotated. The proportion of repeat sequences in the genome was 55.3 %, mainly long terminal repeats (LTRs). Depending on the coverage of the repeats, 14 telomeres and 9 centromeric regions on the chromosomes were predicted. Sequencing technology Oxford Nanopore PromethION; DNBSEQ-T7; PacBio. This genome is available in the CarrotOmics Blast Search |
