Building near-complete plant genomes

Year: 2020

Type: review

Abstract: Plant genomes span several orders of magnitude in size, vary in levels of ploidy and heterozygosity, and contain old and recent bursts of transposable elements, which render them challenging but interesting to assemble. Recent advances in single molecule sequencing and physical mapping technologies have enabled high-quality, chromosome scale assemblies of plant species with increasing complexity and size. Single molecule reads can now exceed megabases in length, providing unprecedented opportunities to untangle genomic regions missed by short read technologies. However, polyploid and heterozygous plant genomes are still difficult to assemble but provide opportunities for new tools and approaches. Haplotype phasing, structural variant analysis and de novo pan-genomics are the emerging frontiers in plant genome assembly.
