After fertilization, the zygote in Arabidopsis elongates and divides asymmetrically into two cells of different size and fate, thereby establishing the apical-basal axis of the embryo.Despite the fundamental importance of this asymmetry for embryo patterning, the underlying mechanisms are poorly understood.During the screen for mutations disrupting zygotic development, two mutants, designated zygotic arrest (zar), impairing the first zygotic cell division, were isolated.

盖茨从小就很喜欢学习,小小年纪就通读《世界大百科全书》。到11岁时,盖茨开始向父母抛出千奇百怪的问题,为难他们。一天,盖茨在餐桌上对母亲大喊大叫,言辞充满讥讽和孩子气
多数人都听过“抗氧化”、“ 解毒”等名词，其关联着“抗自由基”、“抗衰老”、“抗肿瘤”等名词，一般人也熟知许多具抗氧化能力的蔬菜以及食物，但很少人知道抗氧化与解毒其实与人体肝脏自身的功能密切相关。吃某些蔬菜食物可以活化解毒的系统，让身体具有更强的抗肿瘤防衰老的能力。 简单来说，人体中肝脏的解毒机制有两道解毒程序：分别称为第一道解毒程序和第二道解毒程序。此系统主要由细胞色素 P450酶组成，在解毒
