Interactive Multi-Omics: JBrowse 2 and BLAST on BGDB

The VEDA Automated Pipeline: Integrating high-throughput eukaryotic structural annotation, AI-driven homology modeling, and FAIR digital repositories for biodiversity conservation.

High-throughput sequencing continues to generate vast amounts of genomic data, but raw chromosome assemblies and gene coordinates are only as valuable as a researcher’s ability to query and visualize them interactively. Complex non-model plant systems, non-canonical splice forms, and specialized gene clusters require fluid, responsive analytical interfaces that bridge raw sequences with functional context.

To eliminate the friction between raw assembly downloads and exploratory analysis, the Bharat Genome Database (BGDB.org) integrates two browser-native tools: JBrowse 2 and a customized BLAST suite.

Linear and Synteny Visualization via JBrowse 2

Unlike legacy genome viewers that struggle with large contigs or require extensive desktop software installations, JBrowse 2 operates directly in modern web browsers using a plugin-extensible architecture. On BGDB, JBrowse 2 delivers high-resolution views of eukaryotic reference genomes:

• Multiscale Structural Navigation: Seamlessly zoom from entire chromosome scaffolds down to single-nucleotide resolutions, complete with automated gene model tracks generated by the VEDA annotation pipeline.
• Complex Multi-Track Integration: Layer diverse data modalities onto a single coordinate system—including transcript evidence (RNA-Seq/Iso-Seq), GC content landscapes, transposable element distributions, and variant call formats (VCF).
• Comparative Synteny Blocks: Inspect structural rearrangements, large-scale inversions, and gene duplications across related native species through interactive linear synteny views, making evolutionary shifts visible at a glance.

Targeted Sequence Homology with Embedded BLAST

Locating functional homologs or mapping novel primers across diverse subcontinental species requires fast, targeted sequence alignment. BGDB provides a web-native BLAST interface configured against curated reference datasets:

• Lineage-Specific Databases: Run nucleotide (BLASTn) and protein (BLASTp, BLASTx) searches specifically scoped to native flora—including Nelumbo nucifera (Sacred Lotus), Azadirachta indica (Neem), and Santalum album (Sandalwood)—without filtering through unrelated global accessions.
• Direct Hand-off to the Browser: Alignment hits link directly back to their exact genomic coordinates within JBrowse 2, allowing you to instantly inspect the surrounding exon-intron structure, flanking promoter elements, and upstream regulatory regions.
• Custom Parameter Tuning: Fine-tune e-value thresholds, gap penalties, and scoring matrices to capture distant evolutionary homologs in divergent, non-model plant families.

Advancing FAIR, Accessible Biodiversity Research

Under the BioHeritage Program and the Adopt-a-Genome Initiative powered by the Sivasakthi Science Foundation, democratizing access to genomic blueprints is an operational priority. By embedding high-performance exploration tools directly into the browser, BGDB ensures that researchers, conservationists, and students worldwide can query, inspect, and extract biological insights from native eukaryotic genomes without needing high-performance local computing clusters.
