Chinese team builds first 3D cell atlas of rice life cycle, published in Cell
En breve
A Chinese multi-institution team said it has constructed the world’s first three-dimensional spatiotemporal cell atlas covering rice from seed germination to flowering and fruiting, with the paper published online in Cell on the evening of Oct. 6. The atlas integrates genome, single-cell and spatial transcriptome sequencing, and Xinhua reported it covers 10 rice organ or tissue types and 61 developmental stages of the japonica variety Zhonghua 11. Researchers also built a database and a rice single-cell foundation model for global use, which they say can support precise design breeding.

A Chinese research team said it has constructed the world’s first three-dimensional spatiotemporal cell atlas covering the full life cycle of rice, from seed germination to flowering and fruiting, according to Yazhou Bay National Laboratory and reports by Chinese outlets. The paper was published online in the international journal Cell on the evening of Oct. 6, the documents said. The atlas integrates genome sequencing, single-cell sequencing and spatial transcriptome sequencing and is described as a new research resource for understanding rice growth and development and exploring grain quality improvement. [ 1 , 2 , 3 , 4 , 5 ]
Xinhua reported that the work was jointly completed by 12 research institutions, including Yazhou Bay National Laboratory, BGI Life Science Research Institute, Huazhong Agricultural University, Southern University of Science and Technology, Wuhan University and the Institute of Genetics and Developmental Biology under the Chinese Academy of Sciences. Using the japonica rice variety Zhonghua 11 as material, the researchers integrated BGI’s independently developed spatiotemporal omics technology, single-cell omics technology and high-throughput gene sequencers to build an atlas covering 10 types of organs or tissues and 61 developmental stages, according to the report. Xinhua said the team obtained more than 850,000 high-quality cell nucleus data points and more than 340,000 spatial data units, and annotated 119 cell types and 133 cell subtypes. [ 5 ]
According to the documents, the data correspond rice cells’ molecular features with their spatial positions and show changes across developmental stages. Researchers also built a database and a rice single-cell foundation model for global researchers, supporting gene query, spatial expression display and comparative analysis; researchers can examine how genes of interest are expressed in different tissues and developmental stages and decide directions for experimental validation. [ 2 , 4 , 5 ]
Seed-industry researchers cited in the coverage said the results could open a new path for precise design breeding to quickly achieve high and stable yields. Previously, improving a rice trait by directly changing a specific gene could affect multiple traits, according to the reports. With the atlas and model, experts hope to conduct targeted optimization, greatly reduce adverse chain reactions described as “顾此失彼” and explore more targeted regulation strategies. [ 2 , 4 ]
The official report linked the work to the dining table. Rice is mainly the endosperm, which determines the taste and nutrition of cooked rice, and the study found that endosperm cells have fine spatial division: cells near the “back” are enriched with genes related to carbohydrate metabolism and starch synthesis, while those near the “belly” tend toward storage protein synthesis genes, Xinhua reported. The report also said the same key regulatory factor can perform different functions in different cellular spatial environments. Future scientists seeking better-tasting or more nutritious rice could use the atlas to make more targeted spatial partition regulation strategies, it said. [ 5 ]
Por qué importa
The documents present the atlas as a new research resource for understanding rice growth and improving grain quality. Seed-industry researchers cited in the coverage said it could open a faster path to precise design breeding for high and stable yields and help reduce unintended trade-offs when changing traits. An official report also says the findings could guide targeted regulation of rice endosperm to breed better-tasting or more nutritious rice.
