查询词典 gametophytic

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。

On the basis of results of our test,we suggest that low temperature pretreatment changes content of endogenous IAA and iPA of anther,thus interrupts previous developmental direction of pollen and induces microspores develop from a gametophytic way to a sporophytic way.

根据实验结果，推测低温预处理改变了花药内源IAA和iPA含量，阻断了花粉原来的发育方向，使其由配子体的发育途径转向孢子体的发育途径。

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。

Recent data have provided clear insights into some aspects of self-recognition and rejection in the SI response of three types,the single-locus sporophytic and two distinct forms of single-locus gametophytic SI.

高等植物在长期的进化过程中，通过雌蕊识别并拒绝遗传上相近的花粉，防止近亲繁殖、保持遗传多样性，该机制被称为植物自交不亲和性。

Samples of conchocelis and gametophytic baldes of both SF-1 and Y-6 (isolated from SF-1 line) lines had a unique allele on PC40 locus, indicating that it can be used as a marker to distinguish these two lines from the others.

在引物PC-40界定的遗传座位上，2个优良品系申福1号和优质6号（以申福1号为母本选育出来的品系）的丝状体和叶状体均出现了区别于其他品系的等位基因，显示对这2个优良品系进行SSR特异性标记是可能的。

Epiphytic bacteria were isolated from sporophytic thallus collected from Qingdao and Dalian or gametophytic filaments stored in our lab of Laminaria japonica. Identification was done using both traditional physiological and biochemical way and molecular method. Phylogeny tree was established based on 16S rRNA gene sequence analyses, and some sequences of epiphytic strains from both sporophyte and gametophyte were different from all the sequences already exit and could be the new species.

采用生理生化和16S rRNA基因序列比对的方法对从两个海区采集的海带孢子体以及实验室中保存的海带配子体样品的外生菌分别进行组成分析，16S rRNA基因序列揭示了在海带孢子体和配子体的外生菌中都存在一些与现有数据库中序列的遗传关系较远的菌株。

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。

After one month farming of conchosporelings of "Shenfu No.1" in the sea, the average length of gametophytic blade was over twice as much as the traditiona...

申福1号苗种下海养殖1个月，其藻体平均长度是传统品种的2倍多，表现出生长快，生长期长，不易成熟，色泽好等优点，增产增值效果很显著。

The inheritance of poly-eggs in the crosses between APⅣ,IR36,MinghuiNo.77 and Longtepu B was examined.It was concluded that the production of poly-egg is probably controlled by gametophytic genes,rather than by sporophytic genes.

通过APⅣ与IR36、明恢77和龙特浦B杂交研究APⅣ的多卵遗传行为，表明APⅣ的多卵性状可能不是由孢子体基因决定的，而是由配子体基因决定的，属配子体遗传的范畴。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
