主 题:Cattle Cis-regulatory elements Muscle Selection sweep 3D genome
摘 要:Background Sharply increased beef consumption is propelling the genetic improvement projects of beef cattle in ***-dimensional genome structure is confirmed to be an important layer of transcription *** genome-wide interaction data of several livestock species have already been produced,the genome structure states and its regulatory rules in cattle muscle are still *** Here we present the first 3D genome data in Longissimus dorsi muscle of fetal and adult cattle(Bos taurus).We showed that compartments,topologically associating domains(TADs),and loop undergo re-organization and the structure dynamics were consistent with transcriptomic divergence during muscle ***,we annotated cis-regulatory elements in cattle genome during myogenesis and demonstrated the enrichments of promoter and enhancer in selection *** further validated the regulatory function of one HMGA2 intronic enhancer near a strong sweep region on primary bovine myoblast *** Our data provide key insights of the regulatory function of high order chromatin structure and cattle myogenic biology,which will benefit the progress of genetic improvement of beef cattle.
