“In Chinese art, each month is represented by a flower, and Moutan is specifically the flower for March” — Mark Haworth-Booth. At the beginning of March, we are sharing the genomic research of China’s national favorite, the king of the flowers, Moutan (tree peony, Paeonia ostii), one case from BMKGENE.
On November 28, 2022, Shanghai Chenshan Botanical Garden published the latest research results of peony genomics entitled “Genomic basis of the giga-chromosomes and giga-genome of tree peony Paeonia ostii” in the international journal Nature Communications.
This study successfully deciphered the genomic genetic code of the high-quality chromosome level of Fengdan peony and the molecular mechanism of the formation and maintenance of super-large chromosomes. This is the largest chromosome (1.78-2.56Gb) in land plants that has been sequenced in the world so far, and it is also one of the largest genomes (12.28Gb) in sequenced dicotyledonous plants. Further, they conducted genome-wide association studies (GWAS) on 448 accessions using SLAF-seq, and identified several genes in the key nodes of fatty acid biosynthetic pathway, which may function in high level of ALAs synthesis in tree peony seeds.

BMKGENE has supplied the genome assembly and SLAF-seq services for this study and accumulated essential experience of complex genome assembly. We expect to hear more about your next project.
