Macauba Palm Chromosome-Scale Phased Genome Assembly and Annotation

A 1.94 Gbp chromosome-scale, haplotype-resolved genome assembly for the oil-producing macaúba palm (Acrocomia aculeata). The dataset includes predicted protein-coding genes, coding sequences, proteins, and genome annotation files, generated by Matheus Scaketti using Oxford Nanopore, PacBio HiFi, and Hi-C sequencing technologies. It was last updated on April 30, 2026.

Use Cases

• Comparative genomics analyses based on the described chromosomal collinearity with related palm species.
• Evolutionary studies of repetitive elements based on the reported ~73-77% repetitive content and ~55% LTR retrotransposons.
• Gene discovery and functional annotation for molecular breeding based on the 28,367 predicted protein-coding genes.
• Assessing genome assembly quality for other species using metrics like the LAI score of 25.11 and BUSCO completeness of 98.9%.

Strengths

• High contiguity with an N50 of 143.43 Mbp and a quality value (QV) of 76.4.
• High completeness with 98.9% complete BUSCOs for predicted proteins and k-mer completeness exceeding 90%.
• Provides two fully phased haplotypes (Hap1: 1.93 Gbp; Hap2: 1.92 Gbp), each resolved at chromosome scale.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some analyses.
