雄核发育

Observing the mature embryo sac of the mutant: It was found thatthe embyo sac appeared in typical polygonum type and more than 90% of the embryo sac hadintegral inner structure. They had egg apparatus, two polar nucleus and three antipodal cells , and their position in the embryonic sac was normal .

幼穗分化、成熟胚囊观察发现，90％以上的胚囊具有完整的内部结构，有卵器、两个极核及多个反足细胞，且位置正常，胚囊呈现典型的蓼型结构；同时还观察到雌、雄器官的发育是同步的。

This research could give basic information about the dominant genie male sterility in Brassica napus and male gametogenesis.

本研究为更深入的研究甘蓝型油菜显性核不育的育性相关基因提供了基础，并对雄配子的发育研究也具有一定参考价值。

The isonucleus-allocytoplasmic materials ms-Xinong 1376,-Xinong 1376, and ms-Xinong 1376 were used to investigate the protein expression profile in mononucleated anaphase anthers of wheat (Triticum aestivum L.) after silver staining and analysis by PDQuest software. About 320 to 350 distinct protein spots were detected reproducibly.

为了研究小麦雄性不育蛋白表达机制，以具有异质同核的3个亲本：即遗传型不育系ms-西农1376、对应的保持系-西农1376和生理型(化学杀雄剂SQ-1诱导)雄性不育系ms-西农1376为材料，利用IEF/SDS-PAGE凝胶电泳技术，对发育到单核后期的花药全蛋白特异性进行了比较分析，得到320~350个清晰的蛋白点。

The fertilization was processed by sperm in mature male gametophyte combining with egg cell on the top of archegonia on June 15 or so.

摘要樟子松发育成熟的雄配子体中的精子6月15日左右在颈卵器中上部与卵细胞结合，进行受精作用，其后，受精卵进行游离核分裂，形成8个子核时，开始形成细胞壁。
