The Almond Expression Atlas: A comprehensive multi-tissue transcriptomic resource for almond gene expression

The Almond Expression Atlas v1.0 integrates RNA-seq from 142 untreated and control samples across 17 projects to standardize expression for 25,225 annotated genes in Prunus dulcis.

• Why it matters: Crop adaptation and trait improvement depend on understanding gene regulation, but existing almond transcriptomic data are fragmented, limiting comparability and reuse.
• What they did: The team curated 142 samples via metadata standardization and processed them with a unified pipeline, generating median TPM profiles and Bgee rank-based expression calls for cross-dataset comparability.
• The result: The atlas supports tissue-specific candidate gene discovery and, in two use cases, identifies gene sets linked to bud dormancy transitions and prioritizes RT-qPCR reference genes in almond.
