摘要
Dear Editor,Genome assembly is typically a two-stage process： paired sequencing reads are joined into contigs, and contigs are assem- bled into scaffolds. Over the past 10 years, next-generation sequencing （NGS） technologies have become inexpensive, routine, and widespread. As a result, most plant genomes that are sequenced by NGS produce “drafts” that are always contig or scaffold maps remaining in a more or less advanced stage of completion （Claros et al., 2012）. Slow advances in the technology for the de novo assembly of scaffolds into chromosome-scale scaffolds have become the main restriction to the completion of and high-quality genome sequence acquisition.
