Explanation
|
Gene Expression Omnibus database: accession number GSE39298. Polycomb group protein, Extra Sex Combs (ESC)-like genes. an OsWD40 superfamily member protein. df (Epi-df) might be an epigenetic mutant that is heritable but unstable with a low frequency of spontaneous reversion back to a normal. This allele causes a dwarf stature and various floral defects. FIS-PRC2 (FERTILIZATION-INDEPENDENT SEED-POLYCOMB REPRESSOR COMPLEX2) component. GO:2000014 regulation of endosperm development. GO:1902040: positive regulation of seed dormancy process. TO:0000942: aleurone layer morphology trait. GO:0071514: genomic imprinting. TO:0020076: phenolic compound content. TO:0006044: magnesium content.
