- Genbank accession number
- Key message
- Here, we identify a gain-of-function epi-allele (Epi-df) of rice (Oryza sativa) FIE1; this allele causes a dwarf stature and various floral defects that are inherited in a dominant fashion
- OsFIE1 is expressed only in endosperm; the maternal copy is expressed while the paternal copy is not active
- Imprinted Gene OsFIE1 Modulates Rice Seed Development by Influencing the Nutrient Metabolism and Modifying Genome H3K27me3.
- The RNAi of OsFIE1 and homozygous T-DNA insertion mutant osfie1 led to smaller seed, delayed embryo development, smaller aleurone layer cell, and decreased seed set rate
- OsFIE1 specifically expressed in endosperm, and mRNA of OsFIE1 also enriched in inner seed coat with the corresponding PcG members of OsiEZ1 and OsCLF
- Meanwhile, the contents of seed storage proteins and Ile, Leu, and Val were decreased, accompanied with the down-regulation of multiple transcription factors, storage protein synthesis and amino acid metabolism related genes in OsFIE1-RNAi lines and osfie1
- The newly evolved N-terminal tail of OsFIE1 was probably not the cause of the adverse effects on vegetative growth
- The mutant osfie1 produced smaller seeds and displayed reduced dormancy, indicating that OsFIE1 predominantly functions in late seed development

- OsFIE1~Epi-df, OsFIE2, Functional divergence of two duplicated Fertilization Independent Endosperm genes in rice with respect to seed development, OsFIE1 and OsFIE2 are two FIE homologs in the rice genome
- OsFIE1~Epi-df, OsFIE2, Functional divergence of two duplicated Fertilization Independent Endosperm genes in rice with respect to seed development, Here, we showed that OsFIE1 probably duplicated from OsFIE2 after the origin of the tribe Oryzeae, but has a specific expression pattern and methylation landscape
