Complete mitochondrial genomes(mitogenomes)of plants are valuable resources for nucleocytoplasmic interactions,plant evolution,and plant cytoplasmic male sterile line breeding.However,the complete assembly of plant mitogenomes is challenging due to frequent recombination events and horizontal gene transfers.Previous studies have adopted Illumina,PacBio,and Nanopore sequencing data to assemble plant mitogenomes,but the poor assembly completeness,low sequencing accuracy,and high cost limit the sampling capacity.Here,we present an efficient assembly toolkit(PMAT)for de novo assembly of plant mitogenomes using low-coverage HiFi sequencing data.PMAT has been applied to the de novo assembly of 13 broadly representative plant mitogenomes,outperforming existing organelle genome assemblers in terms of assembly accuracy and completeness.By evaluating the assembly of plant mitogenomes from different sequencing data,it was confirmed that PMAT only requires 1× HiFi sequencing data to obtain a complete plant mitogenome.The source code for PMAT is available at https://github.com/bichangwei/PMAT.The developed PMAT toolkit will indeed accelerate the understanding of evolutionary variation and breeding application of plant mitogenomes.
