Although cucumber,tomato and soybean as dicots have been previously classified as the same type of plant(namely mechanismⅠ plant) according to their reaction to iron deficiency,actually their specific reactions to iron deficiency stress were different respectively.

黄瓜、番茄和大豆同是双子叶植物，缺铁诱导的适应性机制都属于机理I，但是它们在适应缺铁胁迫的具体反应上却各有不同。

We hope to share this campus flora book with you soon. This year we will introduceto you some ferns, herbaceous monocots and dicots, and wetland plants in the Ecological Pond.

本年度将以蕨类植物、单子叶和草本双子叶植物及生态池畔的湿地物种为主，继续介绍院区内多样的植物。

By comparing their sequences with homologues from other plants, it was found that GME genes were highly conserved among plant species, though phylogenetic study showed that all known GMEs could be divided into two distinct groups corresponding to monocots and dicots.

通过逆转录PCR技术从水稻成熟叶片中克隆到两个GME基因的cDNA序列，并与其他植物物种中的GMEs进行比对，结果显示，GME基因在所有植物物种中高度保守，尽管进化树分析表明单子叶植物GMEs和双子叶植物GMEs在进化上相互独立。

Further isomerization and substitution of this central intermediate leads to the synthesis of other flavonoids. CHSs has been isolated from different plant species, including both monocots and dicots, some of their genomic DNAs and/or cDNAs have also been isolated.

目前，包括单子叶和双子叶植物的很多物种中，有的物种查尔酮合成酶已经得到纯化且基因组、cDNA克隆得到分离，有的或者得到了纯化酶，或者分离得到了基因组、cDNA克隆。

The apparent selective establishment criteria of the new strips may explain the low similarity in species composition between the original boundary and the new boundary plots: only non-woodland perennial monocots and dicots had high establishment rates in the herbaceous strips in all boundary types.

表观选择性建立标准的新带可以解释低，在相似的物种组成与原选区分界及新的边界情节：只有非林地多年生monocots和双子叶植物有较高的建立利率，在绿草带的所有边界类型。

Firstly, both cDNAs were isolated from the rice mature leaves using RT-PCR technique. By comparing their sequences with homologues from other plants, it was found that GME genes were highly conserved among plant species, though phylogenetic study showed that all known GMEs could be divided into two distinct groups corresponding to monocots and dicots.

通过逆转录PCR技术从水稻成熟叶片中克隆到两个GME基因的cDNA序列，并与其他植物物种中的GMEs进行比对，结果显示，GME基因在所有植物物种中高度保守，尽管进化树分析表明单子叶植物GMEs和双子叶植物GMEs在进化上相互独立。

The main root axis from which smaller root branches arise; a root system with a main root axis and smaller branches, as in most dicots.

具有侧根的主根轴；由主根和侧根组成的根系，见于大多数双子叶植物。

To enhance the aphid-resistant, gene GNA34 was directly mutagenized to revert 9 of XCGs and XTAs of the least favored codons to preferred codons in dicots without changing amino acid composition.

为了提高所克隆的GNA34基因在双子叶植物中的抗蚜活性，我们对GNA34基因进行了改造。

DNA C-value is of practical value in the forecast of the invasiveness of exotic species. However, such predictions must be made with comparisons within families because the DNA C-values vary greatly between woody and herbaceous species, between monocots and dicots, between annuals and perennials, and especially among families.

DNA C-值在预测外来物种的入侵性方面具有一定的应用价值，但是，由于在木本植物和草本植物之间、单子叶与双子叶植物之间、一年生和多年生植物之间，特别是在不同的科之间，植物的DNA C-值较明显的差异，因此，根据DNA C-值预测外来物种的入侵性，应该严格地限于同一科内的相关物种间的比较。

The main root axis from which smaller root branches arise; a root system with a main root axis and smaller branches, as in most dicots.

直根 Taproot 具有侧根的主根轴；由主根和侧根组成的根系，见于大多数双子叶植物。
