Single-nucleus sequencing deciphers developmental trajectories in rice pistils

Angiosperms possess a characteristic life cycle with an alternation of sporophyte and gametophyte generations, which happens in plant organs like pistils. Rice pistils contain ovules and receive pollen for successful fertilization to produce grains. The cellular expression profile in rice pistils is largely unknown. Here we show a cell atlas of rice pistils before fertilization by droplet-based single-nucleus RNA sequencing. The Ab initio marker identification validated by in situ hybridization assists the cell-type annotation, revealing cell heterogeneity between ovule and carpel lineages.
