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.

PHERES1控制胚乳基因印迹和种子发育。

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，印迹基因的印迹驱动因素和功能仍然知之甚少。Batista等。确定I型MADS盒转录因子（TF）PHERES1（PHE1）是胚乳发育所需的某些印迹和非印迹基因的关键调节因子。
