"Ka litšoantšo tsa Sechaena, khoeli e 'ngoe le e' ngoe e emeloa ke palesa, 'me Moutan ke palesa ka ho khetheha bakeng sa March" - Mark Haworth-Booth.Mathoasong a March, re arolelana lipatlisiso tsa genomic tsa moratuoa oa naha oa Chaena, morena oa lipalesa, Moutan (sefate peony, Paeonia ostii), nyeoe e le 'ngoe e tsoang ho BMKGENE.
Ka la 28 Pulungoana 2022, Serapa sa Botanical sa Shanghai Chenshan se phatlalalitse liphetho tsa morao-rao tsa lipatlisiso tsa peony genomics tse nang le sehlooho se reng "Genomic basis of the giga-chromosomes and giga-genome of tree peony Paeonia ostii" koranteng ea machaba ea Nature Communications.
Phuputso ena e atlehile ho manolla khoutu ea liphatsa tsa lefutso tsa boemo bo holimo ba chromosome ea Fengdan peony le mokhoa oa limolek'hule oa ho theha le ho hlokomela li-chromosome tse kholo haholo.Ena ke chromosome e kholo ka ho fetisisa (1.78-2.56Gb) limela tsa mobu tse seng li hlophisitsoe lefatšeng ka bophara ho fihlela joale, hape ke e 'ngoe ea liphatsa tsa lefutso tse kholo ka ho fetisisa (12.28Gb) limela tsa dicotyledonous tse latellanang.Ho feta moo, ba ile ba etsa lithuto tsa genome-wide association (GWAS) ho li-accessions tse 448 ba sebelisa SLAF-seq, 'me ba tseba mefuta e mengata ea liphatsa tsa lefutso libakeng tsa bohlokoa tsa mafura a acid biosynthetic pathway, a ka sebetsang boemong bo phahameng ba ALAs synthesis peo ea sefate sa peony.
