Crop Improvement
The rice on your plate took a precisely choreographed path from seed to seed, and this map of that journey could help breeders grow varieties that resist drought or pack more nutrition into every grain.
Researchers tracked gene activity in over 850,000 individual rice cells across the plant's entire life, from a single fertilized seed all the way to a new seed. They found that different sides of the same organ, like the top and bottom of a rice grain, run completely different genetic programs, controlling where starch and protein end up. This kind of detailed map helps scientists understand the hidden rulebook plants use to build themselves, which could guide future efforts to breed hardier, more nutritious rice.
Key Findings
Atlas profiled 851,725 individual cell nuclei and 347,640 spatial tissue locations across 10 rice organs and 61 developmental stages
Identified 119 distinct cell types and 133 subtypes spanning the full rice lifecycle from embryo to mature plant
Discovered dorsoventral (top-bottom) transcriptional asymmetry in the endosperm that separately controls starch and protein accumulation, and identified OsARF1 as a regulator acting differently across developmental contexts
chevron_right Technical Summary
Scientists built a massive 3D map tracking gene activity across every stage of rice growth, from seed to seed, covering 10 organs and over 850,000 individual cells. This atlas reveals how plants coordinate development in space and time, offering a blueprint that could help breed better crops.

Original paper
A spatiotemporal lifecycle atlas decodes spatial coordination in rice.
How gene expression programs are coordinated across space and time to build a complete plant remains poorly understood. Here, we combine high-resolution spatial transcriptomics, single-nucleus RNA ...

Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
