PPNID

PPNID identifies plant-parasitic nematode species using authenticated barcoding sequences and phylogenetic and distance-based analyses to support taxonomic, ecological, and agricultural research.

Key Features:

• Manually Curated Database: Provides a collection of authenticated barcoding sequences for plant-parasitic nematodes.
• Automatic Pipeline: Executes an automated pipeline for rapid species identification from query sequences.
• Alignment Functionality: Performs sequence alignments to examine mutation distribution and detect nucleotide autapomorphies for species delimitation.
• Genetic Distance Analysis: Computes genetic distances to assess relationships among sequences.
• Plot and Maximum Likelihood Phylogeny Analysis: Produces plots and infers maximum likelihood phylogenies to support phylogenetic species delimitation beyond simple similarity searching.

Scientific Applications:

• Ecological Studies: Enables accurate identification of plant-parasitic nematodes for ecological surveys and biodiversity assessments.
• Agricultural Management: Supports diagnosis and monitoring of PPNs to mitigate the economic impact of these pests on agriculture.
• Taxonomic Classification: Assists taxonomic classification and species delimitation through autapomorphy detection and phylogenetic analyses.
• Phylogenetic Research: Facilitates reconstruction of nematode evolutionary relationships using maximum likelihood phylogenies and genetic distance analyses.

Methodology:

Uses an automated species-identification pipeline, sequence alignment to examine mutation distribution and identify nucleotide autapomorphies, genetic distance analysis, plotting, and maximum likelihood phylogeny inference, alongside similarity searching.
