查询词典 zygomorphy

This is the first report that not only the differences of flower symmetry genes expression but also expression timings may result to zygomorphy/actinomorphy transition.

本研究首次报导不仅对称基因表现位置，甚至时间也是关键性因素，因而促成残存两侧对称的变异型辐射对称花的形成。

However, among zygomorphic Gesneriaceae species, some species have evolved from zygomorphy back to actinomorphy.

相较於辐射对称花，两侧对称花常具专一传粉者并有较高的授粉效率，故其种化速度亦常较前者来得快。

Based on the study in Lotus japonicus, a model legume plant in Papilionoideae, scientific groups led by Luo Da demonstrated that TCP proteins have been independently recruited as determinants of petal identities along the dorsoventral axis in two distant lineages of flowering plants Antirrhinum majus and Lotus japonicus, suggesting a synapomorphic origin for the mechanisms in the control of floral zygomorphy.

以蝶型花亚科的百脉根为研究对象，罗达等研究组阐明了在豆科与其他物种基因组中调控花对称性发育的分子机制具有共源性，揭示了在高等植物花形进化过程中，不同进化关系的开花植物独立地招募TCP基因，调控了两侧对称花发育过程中背腹轴的发育。

The water chamber takes the shape of tilting cube, in favor of uniform distribution of cooling water on tube plate surface. The tube bundle is divided into two groups of zygomorphy according to the bisection system and it has eight support clapboards. The siphonopore center of each clapboard increases a certain distance corresponding to that of two tube plates and the cooling tube takes the shape of arch. The two-way cooling water of bisection flows through the condenser in opposite direction so as to improve the distribution of heat load for tube bundle. Around the throat of condenser, the final stage low-pressure heater, air extraction tube, intake device of bypass exhaust and the like are deployed.

它的特点是：水室呈倾斜立方体形状，有利于冷却水流在管板面上均匀分布；由于采用对分制，管束相应地分为左、右对称的两组，并且管束设有八块支撑隔板，每块隔板的管孔中心相对于两端管板的管孔中心依次抬高一定的距离，以使冷却管呈拱形状；对分制的两路冷却水以相反方向流过凝汽器，从而改善管束的热负荷分布；在凝汽器喉部布置了末级低压加热器，抽汽管道及旁路排汽接受装置等。

In addition, the weak-ened expression of ObCYC1 near flowering is correlated with the flower morphology of Oreocharis which is characteristic of weak zygomorphy.

另外， 由于大叶石上莲的背部花瓣较两侧和腹部花瓣小，因此，在功能上ObCYC1可能起抑制背部花瓣生长作用而CYC基因则促进背部花瓣生长。

On the other hand, DIVARICATA expresses in ventral petals and antagonize with RAD to generate zygomorphy.

在非洲堇中找到同源基因SiCYC、SiRAD、SiDIV，藉由RT-PCR比较检测野生型及变异型各组织间的基因表现差异，探讨非洲堇花对称性状改变的机转。

The knock-down of the three LjCYC genes gives rise to the ventralized identity to all petals, which are keeled shape, resulting in a floral transformation from a zygomorphy to an asymmetry, indicating that the asymmetry floral pattern could be a ground stage before LjCYC1, LjCYC2 and LjCYC3 being recruited in the control of floral asymmetrical development in Lotus japonicus.

本实验得到了LjCYC1、LjCYC2和LjCYC3表达均下调的转基因株系L1+2Ri/kew1，该植株所有花瓣呈现腹部属性，出现了花瓣形态全是龙骨瓣状的非对称花瓣，花型也从两侧对称转化为无对称面；这种花型表明，在LjCYC1、LjCYC2和LjCYC3等三个基因全失活的情况下，龙骨瓣状花瓣应该是一个基准状态。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
