GRAFT: Biological Graph and Hypergraph Benchmarks for Linked Gene Expression and Phenotypic Trait Prediction in Arabidopsis thaliana
TL;DR
A gap exists in predicting phenotypic traits from gene expression data in plants, particularly in Arabidopsis thaliana. GRAFT, a benchmark framework utilizing biological graphs and hypergraphs, was developed to facilitate this prediction.
✦ Why It Matters
Researchers can leverage GRAFT to enhance the accuracy of trait predictions in plant genomics.
Key Takeaways
- Utilize the GRAFT dataset for advanced phenotype prediction tasks.
- Leverage multimodal data to explore gene-trait associations.
- Benchmark your models against GRAFT's hypergraph baseline.
- Investigate higher-order gene pairings for deeper insights.
Full Summary
Understanding the relationship between genes and traits is a major challenge in biology, particularly in plant breeding. Current datasets often lack connections between gene expression and trait data, limiting research potential.
GRAFT, or Gene-Graph Regression for Arabidopsis Functional Traits, is a curated multi-modal dataset that links gene expression profiles with phenotypic trait measurements specifically for Arabidopsis thaliana, a key model organism. This dataset supports tasks like phenotype prediction and interpretable graph learning, and includes benchmarks for conventional regression and a biologically-informed hypergraph baseline to validate gene-trait associations.
GRAFT is the first dataset to provide such comprehensive multimodal gene and trait data for the same specimens, aiming to enhance understanding of genotype-phenotype relationships through higher-order gene pairings and diverse trait data sources.
