花粉管

To further address how OSCK1 affect the pollen germination process, plasmids which can overproduce GFP-fused OSCK1 proteins were bombarded into the germinating lily pollen.

为了进一步了解OSCK1如何影响花粉管萌发，利用基因枪将融合GFP之OSCK1质体送入正在萌发的百合花粉管中，进行暂时性基因表现分析。

The process of pollen tube growth involves many aspects, especially the dynamics of the cytoskeleton and cytoplasmic movement.

花粉管的生长过程包括许多方面，其中最为重要的是花粉管细胞骨架动态和胞质运动。

The process of pollen tube growth involves many aspects, especially the synthesis of cell wall and the cytoplasmic movements.

花粉管的生长过程包括许多方面，其中最为重要的是花粉管细胞壁的合成和胞质运动。

The locomotion of sperm cells from pollen grain into the tube was examined by using the above technique.

用同样的方法，也观察了精细胞在花粉管中的运动。成对的精细胞可以从花粉管中释放出来。

The regulation of pollen germination and tube growth has also been a good model system for studying signal transduction mechanisms in higher plant cells.

花粉的体外萌发和花粉管的定向生长是受复杂的信号传递机制调控的，论文的最后一部分证实了cAMP在花粉管的萌发及生长过程中的作用。

CaM mRNA was substantially expressed in thetapetum, stigma, pollen tube track, degenerated synergid and transfusion parenchymacells. Lesser but yet significant amounts of CaM mRNA were also localized in themicrospore mother cells, microspores, pollen, antipodal cells, egg cell and central cell.

钙调素mRNA在绒毡层、柱头、花粉管生长途径、退化助细胞以及维管薄壁细胞中大量表达，也可在小孢子母细胞、小孢子、花粉、反足细胞、卵细胞以及中央细胞中检测到。

Results show that sucrose medium was the best and can see pollen tubes sprout directly;A significant difference in pollen vitality was found among various varieties,Among the 68 varieties the pollens of Longiflorum Hybrids lily was highest;The pollens of tiger lily almost lose vitality.

结果表明：以蔗糖培养基培养法效果最好，并能直接观察到花粉管发育状况；百合不同品种间花粉生活力存在极显著差异，在所测定的68个品种中以麝香系百合的花粉活力为最高；卷丹花粉活力最低，几乎为零。

Cv. Shanyou 21 in this report, method of transforming the CpTI and bar gene to peanut with pollen tube pathway technique was studied, the mechanism of the technique in the peanut was discussed; biochemic ingredient changing among the peanut cultivars was analyzed, and genetic distance was studied with RAPD analysis, we hope that these study will be useful to crop breeding.In the two analyses different 19 peanut cultivars were analyzed by RAPD technique respectively.

本论文研究了用花粉管通道法将CpTI和bar基因转入花生品种&汕油523&和&汕油21&的实验方法，初步探讨了花粉管通道法转化花生的机理，并分析了花生品种间生化成分的变化及和RAPD聚类的遗传距离的关系，以期为花生分子育种提供依据。

Pollen-tube growth down the style is both positively and negatively chemotropic; the tube grows toward chemicals secreted by the pistil, and away from atmospheric oxygen.

花粉管沿着花柱的生长是既有正向性也有负向性的：花粉管向着由雌蕊分泌的化学物质生长，同时远离空气中的氧气生长。

The pollen tube may grow down the stylar canal , or it may secrete enzymes that digest the tissue of style , creating a path for the tube .

花粉管可能沿着花柱道向下生长，也可能分泌消化酶分解花柱组织，为花粉管创造一个通道。

He and Nina moved to California and lived at 2005 Ivar Street, Apt.

他和Nina搬到加州，并在2005年伊瓦尔街，公寓生活。

Droperidol （ potently inhibits transfected HERGchannels and this is the probable mechanism for QT prolongation.

氟哌利多有效地抑制了转染的 HERG 钾通道，可能是 QT 间期延长的机制。
