Research focus
From phloem unloading to storage accumulation
Spatial transcriptomics resolves how developing kernel tissues coordinate carbon allocation and the formation of starch, protein and oil reserves.
Molecular markers
Marker genes support tissue annotation and the study of compartment-specific programs.
Filling stages
Early, middle and late grain-filling snapshots capture developmental dynamics.
Use the atlas
Inspect a gene in its developmental context.
Search B73v4 GeneIDs to review expression summaries and request a spatial plot from the linked analysis service. Use the reference images to compare tissue patterns across the atlas.
