At the reproductive stage, RA68 was expressed in the inflorescence meristem, the tip of rachis branch, spikelet primordia, macrospore sac and pollen grains.
原位杂交分析结果表明：在幼苗期RA68主要在幼芽胚芽鞘的内外层细胞和幼叶原基的表层细胞中表达；转入生殖生长期后，在花序分生组织、枝梗原基顶端、花器官原基、大孢子囊和花粉粒中表达。

Microspore Ye as the feather, small sporophyll sac formed by the polymerization, each polymer capsules formed by four small sporangia, small spores with dual airbags, and airbag Pinaceae pollen is similar to large sporophyll from the central axis and arranged in Brachypodium feather composition, Each Yibing has a shell bucket, each bucket containing shell upright ovules 10-12 months.
小孢子叶枝为羽状，小孢子叶由聚合囊组成，每个聚合囊由4个小孢子囊组成，小孢子具双气囊，与松科植物花粉的气囊相似，大孢子叶由中轴及羽状排列的短柄组成，每一柄上有一个壳斗，每个壳斗内有10—12个直立的胚珠。

In the Filicinophyta, Sphenophyta, and Lyophyta the embryo sporophyte produces a footlike structure that remains embedded in the tissues of the parent gametophyte plant, absorbing nutrients like the suspensor of higher plants.
在真蕨门 filicinophyta ，楔叶门 sphenophyta，和石松门 lycophyta 中，胚胎孢子体产生足状结构，仍然包裹于双亲配子体植物内。胚胎吸收营养的方式同高等植物从胚柄那样吸收营养一样。

The invention clones geranyl pyrophosphate synthase GGPPS gene from the ginkgo to construct plant expression vectors which contain ggpps gene, the ggpps gene is inducted into immature embryos of the ginkgo to induct out the callus tissue by the mediating of agrobacterium tumefaciens, PCR and semiquantitative RT-PCR detect the conformation and expression status of exogenous target gene ggpps, high-performance liquid chromatography and an evaporative light-scattering detector are employed to determine the terpene lactones content inside the callus tissue of the ginkgo, and the obtained callus tissue of the ginkgo of which the terpene lactones content is increased is screened.
本发明从银杏中克隆香叶基香叶基焦磷酸合成酶GGPPS基因，构建含ggpps基因的植物表达载体，用根癌农杆菌介导，将ggpps基因导入银杏幼胚并诱导出愈伤组织，PCR和半定量RT-PCR检测外源目的基因ggpps的整合和表达情况，高效液相色谱法及蒸发光散射检测器测定银杏愈伤组织中萜内酯含量，筛选获得银杏萜内酯含量提高的转基因银杏愈伤组织。

endoderm：内胚叶
外胚叶(ectoderm)为临近滋养层的一层柱状细胞,内胚叶(endoderm)是位居胚泡腔侧的一层立米细胞,两层紧贴在一起. 继之,在外胚叶的近滋养层侧呈现一个腔,为羊膜腔,腔壁为羊膜. 羊膜与外胚叶的周缘续连,故外胚叶构成羊膜腔的底.
