Panonychus citri Genome Sequencing Data for Amitraz Resistance Analysis

An 83.97 Mb genome assembly for the citrus red mite, Panonychus citri, with 11,577 predicted genes. Researchers from Southwest University used whole genome sequencing and bulked segregant analysis to identify a T752C mutation in the β-2R octopamine receptor gene linked to amitraz resistance. The mutation correlates with a 94.40% resistance ratio in field populations.

Use Cases

• Identify genetic markers for pesticide resistance based on whole genome sequencing data.
• Study gene expression changes in resistant strains based on the described down-regulation of the β-2R octopamine receptor gene.
• Validate resistance mechanisms in field populations based on the reported 94.40% correlation between mutation and resistance ratio.
• Compare resistance mechanisms across species based on the described difference from the I61F mutation found in ticks.

Strengths

• High-quality genome assembly with a contig N50 of approximately 1.81 Mb.
• 10,940 annotated genes out of 11,577 predicted genes provide a detailed genetic foundation.
• Strong correlation (94.40%) between the identified T752C mutation and resistance ratio in field populations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
