“Ezobuciko baseShayina, inyanga ngayinye imelelwa imbali, kanti iMoutan iyimbali ngokukhethekile yangoMashi.”— UMark Haworth-Booth.Ekuqaleni kuka-March, sabelana ngocwaningo lwe-genomic lwentandokazi kazwelonke yase-China, inkosi yezimbali, i-Moutan (i-peony yesihlahla, i-Paeonia ostii), icala elilodwa elivela ku-BMKGENE.
Ngomhla zingama-28 kuNovemba 2022, i-Shanghai Chenshan Botanical Garden yashicilela imiphumela yocwaningo yakamuva ye-peony genomics enesihloko esithi “Genomic basis of the giga-chromosomes and giga-genome of tree peony Paeonia ostii” kujenali yamazwe ngamazwe i-Nature Communications.
Lolu cwaningo luchaze ngempumelelo ikhodi yofuzo yezinga eliphezulu lekhromosome ye-Fengdan peony kanye nendlela yamangqamuzana yokwakheka nokugcinwa kwama-chromosome amakhulu kakhulu.Lena i-chromosome enkulu kunazo zonke (1.78-2.56Gb) ezitshalweni zasemhlabeni esilandelwe ngokulandelana emhlabeni kuze kube manje, futhi ingenye yama-genomes amakhulu (12.28Gb) ezitshalweni ezilandelanayo ze-dicotyledonous.Ngaphezu kwalokho, benze izifundo ze-genome-wide association (GWAS) ekufinyeleleni okungu-448 besebenzisa i-SLAF-seq, futhi bahlonza izakhi zofuzo ezimbalwa ezindaweni ezibalulekile ze-fatty acid biosynthetic pathway, ezingase zisebenze ezingeni eliphezulu le-ALAs synthesis kumbewu ye-peony yesihlahla.

I-BMKGENE ihlinzeke ngokuhlanganiswa kofuzo kanye nezinsizakalo ze-SLAF-seq zalolu cwaningo futhi yaqongelela ulwazi olubalulekile lokuhlanganisa igenome eyinkimbinkimbi.Silindele ukuzwa okwengeziwe ngephrojekthi yakho elandelayo.
