PMAT

PMAT assembles complete plant mitochondrial genomes from low-coverage PacBio HiFi sequencing data to support studies of nucleocytoplasmic interactions, plant evolution, and breeding applications such as cytoplasmic male sterility.

Key Features:

• Low-Coverage Requirement: Achieves complete assembly with 1× HiFi sequencing data.
• High Assembly Accuracy and Completeness: Produces assemblies with higher accuracy and completeness than existing organelle genome assemblers, validated on 13 representative plant mitogenomes across diverse species.
• Efficiency with HiFi Data: Leverages HiFi sequencing data to overcome assembly completeness and accuracy issues associated with Illumina, PacBio, and Nanopore technologies.
• Handling Complex Genome Features: Manages recombination events and horizontal gene transfers that complicate mitogenome assembly.

Scientific Applications:

• Plant Evolution Studies: Provides complete mitogenomes for phylogenetic and comparative analyses of plant evolution.
• Breeding Programs: Facilitates analysis of cytoplasmic male sterility relevant to hybrid seed production and breeding.
• Nucleocytoplasmic Interaction Research: Enables investigation of nuclear-mitochondrial genome interactions influencing plant phenotypes and adaptation.

Methodology:

PMAT employs advanced algorithms optimized for HiFi sequencing data to assemble plant mitogenomes.
