In a giving stage after pollination,p53 homologue showed high levels in the antipodal cells,integument,immature endosperm,ovary wall,tracheary elements,and aleurone layer,while c-myc homologue showed low levels in these tissues,only before pollination showed high expression in polar nucleus.

结果发现，在授粉后的一定阶段，在反足细胞、珠被、未成熟的胚乳、子房壁、导管组织和糊粉层中，p53同源基因表达强烈，c-myc同源基因的表达相反，在授粉后的这些组织中基本不表达，而在授粉前的中央细胞的极核中表达水平较高。

Compared to other elements content in different parts of different genotypes of wheat grains, we can find that there was extremely remarkable linear relations between the content of Pb and Cd

植物受重金属的污染往往是多种重金属的复合污染[15]，通过比较不同基因型水稻籽粒同一部位和不同部位Cd含量的差异，发现对Pb、Cd积累的部位差异是一致的，均是糊粉层累积最多，内胚乳最少。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
