Functional divergence of two duplicated Fertilization Independent Endosperm genes in rice with respect to seed development
Fertilization Endosperm genes rice
2023/8/9
Fertilization Independent Endosperm(FIE) is an essential member of Polycomb Repressive Complex 2(PRC2) that plays important roles in the developmental regulation of plants. OsFIE1 and OsFIE2 are two F...
The maternally expressed polycomb group gene OsEMF2a is essential for the endosperm cellularization and imprinting in rice
maternally expressed polycomb group gene OsEMF2 aendosperm cellularization
2023/8/9
Cellularization is a key event in endosperm development. Polycomb group (PcG) genes, such as Fertilization-Independent Seed 2 (FIS2), are vital for the syncytium-to-cellularization transitio...
