异基因的

The allometry of a plant individual can be seen as a fixed trait determined by the inheritance of species, and plants evolve towards optimal allometric trajectory.

植物特定基因型在不同环境下，诸如生物量分配和种群几何学上的一些表型差异，既可由异速生长造成，也可由表型可塑性造成。

Methylation of histone H3 at lysine 9 has a well-established role in heterochromatin formation and gene transcription regulation.

研究表明，组蛋白H3K9甲基化在异染色质形成及基因转录调控中具有重要的作用。

ResultsNo significant differences were found in the cell morphology, growth rate or heterocyst development between the deletion mutant and the wild type strain. But the mutant was more sensitive to Na+-salt under salt-stress.

敲除该基因后，发现缺失突变体的形态、生长速度及异形胞发育与野生型无明显差异，但在盐胁迫条件下，突变体比野生型对钠盐更敏感。

Hyphae with nuclei of different genotypes can fuse to form a heterokaryon.

当含有两种不同基因型的菌丝融合在一起时，可以形成异核体。

During the esophageal canceration course, DNA content and heteroploid rate increased significantly. Cell cycle distribution changed obviously. Expressions of relevant cell cycle regulatory elements were abnormal.

食管上皮癌变过程中，DNA含量及异倍体率增加，细胞周期分布发生了明显的改变，细胞周期相关基因蛋白表达异常。

In this study 2mG2-epsps gene was used to be a selection marker gene, and a series of experiments were designed for determining the time of their screening and selection pressure. The results showed that 1 mM glyphosate isopropylamine and 15 days screening can be effectively inhibited non-transgenic maize callus tissue differentiation. So this research work has provided a safe and effective screening system for corn and other monocotyledons crops.

实验中以2mG2-epsps基因作为筛选标记基因，为确定其筛选时间及筛选压力，进行了玉米愈伤组织对不同浓度草甘膦的抗性实验，确定向培养基中添加浓度为1mM的草甘膦异丙胺盐筛选15天能有效的抑制非转基因玉米愈伤组织的分化，本研究的再生植株的阳性率为45%，为玉米及其它单子叶作物转化提供了一种有效、安全的筛选体系。

The result showed that the polarization of populations and gene fluxes are different in different species. The polarization and gene fluxes of populations of 3 Nitavias are lower except N. sphaerocarpa. The heredity coherence of each population is change from 0.8561 to 0.9694. The polarization in the populations is low, and they have the together ancestor. This is similar to morphology and cytology result, so RAPD is a useful supple mentary method in assessing genetic relationship among Nitraria species.

结果表明：白刺属植物的遗传分化程度和基因流因种而异，除球果白刺以外，其余3种白刺的种群间有很大的基因流，其遗传一致度在0.8561~0.9694之间，而种间遗传分化程度较低，故4种白刺有着相近的祖先，这与形态学和细胞学的分析结果一致，说明RAPD分析方法可从分子生物学角度为白刺属植物的系统学分类提供更为有利和可靠的证据。
