"Hauv Suav kos duab, txhua lub hlis yog sawv cev los ntawm paj, thiab Moutan tshwj xeeb yog lub paj rau lub Peb Hlis" - Mark Haworth-Booth.Thaum pib lub Peb Hlis, peb tab tom sib koom cov kev tshawb fawb genomic ntawm Tuam Tshoj lub teb chaws nyiam, huab tais ntawm paj, Moutan (ntoo peony, Paeonia ostii), ib rooj plaub los ntawm BMKGENE.
Thaum Lub Kaum Ib Hlis 28, 2022, Shanghai Chenshan Botanical Garden tau tshaj tawm cov kev tshawb fawb tshiab ntawm peony genomics hu ua "Genomic hauv paus ntawm giga-chromosomes thiab giga-genome ntawm tsob ntoo peony Paeonia ostii" hauv phau ntawv xov xwm thoob ntiaj teb Nature Communications.
Txoj kev tshawb no tau ntse deciphered lub genomic genetic code ntawm high-zoo chromosome theem ntawm Fengdan peony thiab molecular mechanism ntawm tsim thiab txij nkawm ntawm super-loj chromosomes.Qhov no yog qhov loj tshaj plaws chromosome (1.78-2.56Gb) nyob rau hauv cov nroj tsuag av uas tau sequenced nyob rau hauv lub ntiaj teb no kom deb li deb, thiab nws kuj yog ib tug ntawm cov loj tshaj plaws genomes (12.28Gb) nyob rau hauv sequenced dicotyledonous nroj tsuag.Tsis tas li ntawd, lawv tau ua cov kev tshawb fawb genome-wide Association (GWAS) ntawm 448 accessions siv SLAF-seq, thiab txheeb xyuas ntau cov noob nyob rau hauv cov nodes tseem ceeb ntawm fatty acid biosynthetic txoj kev, uas yuav ua hauj lwm nyob rau hauv siab ntawm ALAs synthesis nyob rau hauv ntoo peony noob.
Xav paub ntau ntxiv txog daim ntawv no ntawm https://www.nature.com/articles/s41467-022-35063-1
BMKGENE tau muab cov genome los ua ke thiab SLAF-seq cov kev pabcuam rau txoj kev tshawb no thiab tau txais kev paub tseem ceeb ntawm kev sib dhos genome.Peb cia siab tias yuav hnov ntau ntxiv txog koj qhov project tom ntej.
