Abstract

The Arabidopsis MEDEA gene is required in maternal tissues to restrict cell proliferation in embryos. Molecular characterisation indicates that MEDEA encodes a Polycomb-group protein, particularly intriguing as MEDEA's maternal effects may be a consequence of genomic imprinting.

摘要

拟南芥MEDEA基因在母体组织中发挥作用，以限制胚胎中的细胞增殖。分子特征表明，MEDEA编码一种多梳蛋白家族蛋白，特别有趣的是，MEDEA的母体效应可能是基因组印记的结果。
