The endosperm is a seed tissue that supports the embryo. In most flowering plant species, the endosperm starts as a coenocyte that cellularizes after a defined number of mitotic divisions. We show that endosperm cellularization is under antagonistic parental control mediated by a family of maternally expressed auxin response factors.

母系表达的生长素反应因子家族触发胚乳细胞化


胚乳是支持胚胎的种子组织。在大多数开花植物物种中，胚乳开始时是在一定数量的有丝分裂后细胞化的双核细胞。我们发现胚乳细胞化处于由母体表达的生长素反应因子家族介导的拮抗性亲本控制之下。
