体外,ES细胞能自发聚集形成胚胎体(EB),分化成许多种细胞类型;
低温预处理对小孢子胚产量有显著影响,不同基因型所需预处理时间不同。
但随着花序处理时间的延长,小孢子产胚率有下降的趋势。
结果表明:高温预处理穗子不仅简便易行,可操作性强,而且得到的胚状体最多。
较易抽薹型材料的产胚能力大于易抽薹型和不易抽薹型。
目的探讨类胚体中残留未分化胚胎干细胞(ESC)的特性。
利用巢式聚合酶链反应检测单个胚胎小体细胞中时钟基因的表达
1·Kinetin was later shown to be inhibitory for embryoid formation.
激动素原来被表明抑制胚状体的形成。
2·Changing temperature treatment could enhance the induction frequency of pollen embryoid.
变温处理可以提高花粉胚状体诱导频率。
3·The bud was differentiated from the embryoid and the callus.
由胚状体和愈伤组织分化芽。
4·The results showed that genotype plays a decisive role on informing embryoid in microspore culture, the induction frequency of embryoids significantly difference among different genotypes As no.
结果表明:供体植株基因型是影响小孢子发生胚状体的关键因素,不同材料之间的诱导频率差异显著;
5·Great success in embryoid induction in a number of plants has been obtained.
在许多植物中诱导胚状体已得到很大的成功。
