配子体

Pear belongs to the kind of gametophytic self-incompatibility, so it is necessary to arrange varieties for pollination or perform artificial pollination for stable yield.

梨是配子体自交不亲和果树，生产中必须配置适宜授粉品种或通过人工授粉才能保证产量。

Based on these observations, we predict that the transmission of GA-signaling genes occurs in a sporophytic manner, since the protein products and/or mRNA transcripts of these genes may be introduced into pollen-carrying mutant alleles, whereas GA synthesis genes are transmitted in a gametophytic manner, since these genes are preferentially expressed after meiosis.

基于这些观察，我们预测该遗传算法，基因信号传输时，在孢子的方式，因为蛋白质的产品和/或基因这些基因的转录可以引入花粉携带突变基因，而合成的基因遗传传递以配子体的态度，因为这些基因是优先减数分裂后表示。

In breeding practice, male gametophytic selection as a plant genetic improvement tool with many advantages such as can be shorten the breeding time limit and raise the selection efficiency.

在育种实践中，利用雄配子体选择对植物进行遗传改良，具有提高选择机率和缩短育种年限等优点。

S-RNase-mediated gametophytic self-incompatibility is controlled by a multiallelic S-locus at which two separate genes, the female and male specificity determinants, are tightly linked.

配子体自交不亲和由具有多基因的单一位点S位点控制，该位点包括紧密连锁的雌性和雄性S决定因子。

Liverworts with bilaterally symmetrical gametophytes; sometimes placed in the order Jungermanniales.

具两侧对称的配子体的苔类的一科；有时包括在顶蒴苔纲的叶苔目中。

The pollen tube enters the female gametophyte from micropylar end and the free nuclei near pollen tube have the average chance to acting as the functional egg.

花粉管从雌配子体的珠孔端进入，珠孔端的游离核行使卵细胞功能的机会是均等的。

It is also suggested that the correlations between pollen-ovule ratio and pollen size , and ovule size should be accounted for in terms of sex allocation theory. During this project, no other effective pollinators except bumblebees and no species-specific pollinator have been observed for all kinds of Pedicularis species.

花粉胚珠比与配子体投资的相关性是植物自身为获得生殖成功，对资源在两性性功能的配置重新调整的结果，性配置理论可以很好的解释这些关系。
