Predicting and validating tomato firmness genes.
Fruit firmness significantly influences tomato quality, impacting shelf-life, consumer acceptance, and transportability at full ripeness. The firmness of tomatoes results from intricate physiological changes, including alterations in cell wall structure, internal turgor pressure, and cuticle integrity. As firmness is governed by a network of genes regulating fruit ripening, identifying new genetic determinants remains a complex challenge. KnetMiner, a knowledge graph-based bioinformatics platform, has traditionally validated known gene-trait relationships. This case study examines whether KnetMiner can proactively assist scientists in identifying novel gene associations, moving beyond validation into predictive hypothesis generation.
- How can KnetMiner integrate multiple biological datasets to highlight candidate genes?
- Can KnetMiner effectively visualise gene associations to facilitate understanding?
- Does KnetMiner provide robust tools for discovering direct literature-supported gene-trait connections?
- Can KnetMiner support hypothesis generation even in the absence of direct prior evidence?

However, to test KnetMiner's predictive potential further, the recently published link to firmness was deliberately removed from the GUN5 network. By using KnetMiner’s AI Summary feature, researchers analysed literature on GUN5, its orthologs, and interacting genes in other species. This approach produced a targeted summary highlighting gene functions related to fruit quality processes. Such summaries significantly enhance scientists' ability to generate hypotheses, suggesting that even in the absence of direct prior evidence, KnetMiner can effectively facilitate new insights and "Eureka" moments.

Accelerating Tomato Breeding with KnetMiner
Our collaboration with a leading plant breeding company has been instrumental in demonstrating KnetMiner’s capability to advance tomato breeding research. It highlights how our platform proactively identifies and validates key genetic targets. - Keywan Hassani-Pak, Founder and CEO

We’ve worked on these updates alongside the experts who use them most and believe they make KnetMiner a more powerful, user-friendly tool, tailored for those who need results fast.
