“…Although many imprinted genes have been identified in plants (Bauer & Fischer, ), few have been functionally investigated (Jiang & Kohler, ). A significant finding of our study is that 58 MEGs and 45 PEGs are associated with genomic regions of grain yield‐related traits, including 1000‐seed weight QTLs (Yu et al ., ; Luo et al ., ; Hua et al ., , ; Xing et al ., ; Hittalmani et al ., ; Septiningsih et al ., ; Thomson et al ., ) (http://www.ricedata.cn/maps.aspx), many of which have been shown to mediate seed morphology and development through biological pathways of energy and metabolism (Asano et al ., ; Li et al ., ; Zhang X et al ., ; Zhu et al ., ). The imprinted genes encoding transcription factors could mediate cell proliferation and endosperm cellularization, and hence affect the seed size (Bauer & Fischer, ).…”
