CS-IAAS_v1.1

A complete bread wheat telomere-to-telomere genome provides insights into the evolution, transcriptome, and proteome of a hexaploid genome Peking University Institute of Advanced Agricultural Sciences, Complete assemblies of huge and complex plant genomes remain a challenge, and the hexaploid wheat genome stands as the most difficult one among staple food crop genomes. Here, we present CS-IAAS, a comprehensive telomere-to-telomere (T2T) gap-free Triticum aestivumL. reference genome, encompassing 14.51 billion base pairs and featuring all 21 centromeres and 42 telomeres. ## The genome sequence of Triticum aestivum cv. Chinese Spring CS-IAAS_v1.1.zip ## Annotation of CS-IAAS_v1.1 All gene structure are in GFF format for both High Confidence and Low Confidence genes. CS-IAAS_v1.1_annotation.zip ## TE Annotation of CS-IAAS_v1.1 TE_v1.1.gff3 Code/Software Packages involved in data analysis pipelines are listed in the Methods.
