- Key message
- Both the OsFIE2 and OsEZ11 genes are strongly expressed in leaf and stem compared to other tissues, including root, anther, ovary, and ovule
- Involvement of rice Polycomb protein OsFIE2 in plant growth and seed size
- Our results suggest that OsFIE2-polycomb complex positively regulates rice endosperm development and grain filling via a mechanism highly different from that in Arabidopsis
- Genetic studies showed that a reduction of OsFIE2 expression led to smaller seeds, partially filled seeds, and partial loss of seed dormancy
- Polycomb group gene OsFIE2 regulates rice (Oryza sativa) seed development and grain filling via a mechanism distinct from Arabidopsis
- The H3K27me3 modification and gene expression in a key helix-loop-helix transcription factor is shown to be regulated by OsFIE2
- Importantly, they produced bigger seed than the wild type, indicating that OsFIE2 may play an important role in seed size
- Gene expression and proteomics analyses found that the starch synthesis rate limiting step enzyme and multiple storage proteins are down-regulated in OsFIE2 reduction lines
- We further examined whether OsFIE2 interacted with OsEZ1 using a yeast two-hybrid system
- In this study, the function of the rice fertilization-independent endosperm gene OsFIE2, which expresses a protein homologous to the Arabidopsis Polycomb protein FIE, was characterized
- Polycomb Protein OsFIE2 Affects Plant Height and Grain Yield in Rice.
- Taken together, these results indicate that OsFIE2 plays an important role in the regulation of plant height and grain yield in rice
- OsFIE2 is expressed in most tissues and the coded protein localizes in both nucleus and cytoplasm
- The CRISPR/Cas9-derived mutant osfie2 exhibited impaired cellularization of the endosperm, which suggested that OsFIE2 is indispensable for early seed development as a positive regulator of cellularization

- OsCLF~SDG711, OsFIE2, Regulation of plant height in rice by the Polycomb group genes OsEMF2b, OsFIE2 and OsCLF., To determine how PcG genes regulate plant height, we investigated the phenotypes of the emf2b mutant and OsEMF2b, OsFIE2 and OsCLF RNAi transgenic plants; they all exhibited dwarf phenotype
- OsCLF~SDG711, OsFIE2, Regulation of plant height in rice by the Polycomb group genes OsEMF2b, OsFIE2 and OsCLF., Reduced cell expansion and cell division of stem caused significant reduction of stem length during mature period of OsEMF2b, OsFIE2 and OsCLF RNAi transgenic plants
- OsCLF~SDG711, OsFIE2, Regulation of plant height in rice by the Polycomb group genes OsEMF2b, OsFIE2 and OsCLF., H3K27me3-modified sites were observed in 95 of the 109 up-regulated genes, and some of them were up-regulated in OsFIE2, OsCLF and OsEMF2b RNAi transgenic plants, and their H3K27me3 levels were reduced in emf2b
