In contrast to mammals, genomic imprinting primarily occurs in the endosperm in flowering plants. Nevertheless, the imprinting drivers and functions of imprinted genes remain poorly understood. Batista et al. identified the type I MADS-box transcription factor (TF) PHERES1 (PHE1) as a key regulator of some imprinted and nonimprinted genes required for endosperm development.
与哺乳动物相反，基因组印迹主要发生在开花植物的胚乳中。然而，印迹驱动因子和印迹基因的功能仍知之甚少。Batista 等人鉴定出 I 型 MADS 框转录因子（TF） PHERES1（PHE1）是一些印迹和非印迹基因的关键调控因子，这些基因对于胚乳发育是必需的。
