gcaPDA: A Haplotype-resolved Diploid Assembler
Abstract Generating chromosome-scale haplotype resolved assembly is important for functional studies. However, current de novo assemblers are either haploid assemblers that discard allelic information, or diploid assemblers that can only tackle genomes of low complexity. Here, we report a diploid assembler, gcaPDA (gamete cells assisted Phased Diploid Assembler), which exploits haploid gamete cells to assist in resolving haplotypes. We generate chromosome-scale phased diploid assemblies for the highly heterozygous and repetitive genome of a maize F1 hybrid using gcaPDA and evaluate the assembly result thoroughly. With applicability of coping with complex genomes and fewer restrictions on application than other diploid assemblers, gcaPDA is likely to find broad applications in studies of eukaryotic genomes..
