查询词典 embryogenesis

The rule of growth and decline about main biochemical material (solubility protein, solubility sugar, SOD and gossypol IAA) contacting with stomatic embryogenesis showed that content of solubility protein and SOD activity was differed in the different period, being lower in earlier callus and reaching maximum in 120 day.

对陆地棉愈伤组织诱导及体细胞胚发生过程中的主要生化物质（可溶性蛋白含量、可溶性糖含量、SOD活性和IAA氧化酶活性）的测定表明，各个时期的可溶性蛋白含量、SOD活性是不同的，在愈伤组织形成初期较低，随着愈伤组织的生长及胚状体的形成，可溶性蛋白含量、SOD活性逐渐上升，在120d时达最大值；而可溶性糖含量在60d时有一个高峰值，在120d时达到最低值；IAA氧化酶活性在60d、120d时酶活较高，90d的酶活较低。

The observation of morphostructure and ultrastructure proved, somatic embryogenesis and plant regeneration system of Symplocarpus nipponicus Makino have been successfully established.

对不同阶段培养材料的形态结构及超微结构的观察证明，成功建立了日本臭菘体细胞发生及植株再生体系。

Plant somatic embryogenesis is a good experimental system for cell differentiation, development, totipotency expression and crop cultivar improvement, which have very important theoretical and practical significance.

植物体细胞胚胎发生是现代生物技术研究中的一个重要领域，它为研究植物细胞的分化、发育、全能性表达和作物品种改良等提供了良好的体系，在理论上和应用中都具有重大意义。

Somatic embryogenesis is a remarkable illustration of plant totipotency,and under appropriate culture medium can develop to an adult plant with high frequency, so it is a excellent system for genetic improvement.

植物体细胞胚发生是植物细胞全能性的重要体现，在适宜的培养条件下能够以较高的频率再生出完整的植株，是植物遗传改良受体系统。

We systematically studied somatic and zygotic embryogenesis and its cytological process. This is the first report on these subjects till now.

本文首次对水曲柳的体细胞胚胎诱导和合子胚与体细胞胚发育的细胞学过程作了系统研究。

The club hair remains within the foreshortened follicle until a new anagen follicle develops in a fashion recapitulating its formation during embryogenesis, and the newly formed hair shaft dislodges the club hair.

新的毛囊的发育遵循生物重演律。新形成的毛干取代杵状毛。

At the earlier period of pregnancy, before the formation of blood vessels, embryogenesis precesses in the hypoxia environment.

低氧作为一种生理性的刺激因素，影响着胚胎的发生、发育及正常功能的维持。

Throughout development, the FAA accounted for only a small proportion (0.16% in fertilised eggs) of the total amino acid pool. Because the egg protein and the total amino acid contents declined with development, it was concluded that the rate of breakdown of yolk protein was higher than the anabolic and catabolic processes during embryogenesis.

由于总蛋白和总氨基酸的含量在发育过程中均呈下降趋势，由此可知，在整个胚胎发生过程中，其卵黄蛋白的水解速度大于胚体同化和异化作用对氨基酸的消耗速度。

In this study, 105 TDFs were in silico mapped in the rice high-density linkage map. Nineteen TDFs were mapped to the quantitative trait loci regions for root growth under water-limited conditions in, at least, two of three rice populations derived from three crosses with the same parent of Azucena (Bala×Azucena, IR64×Azucena and IR1552×Azucena). Four of 19 genes (T37, L16, T17 and T7) were mapped based a RIL population of IR1552×Azucena by southern blot analysis. Five genes encode putative or hypothetical protein. Other 14 genes were similar with known genes in databases including expansin (OsEXP2), late embryogenesis-abundant gene , an SR-related protein essential for spliceosome assembly (SART1), autophagocytosis protein , bHLH protein, fruit-ripening protein similar to ASR, nickel-binding protein 2A, DNA-binding protein, pyruvate dehydrogenase kinase , stomatin-like protein, SR1 induced by sucrose starvation, vacuolar protein sorting protein (VSP33a), gibberellin action negative regulator and retroelement.

根据核苷酸序列将105个基因电子定位到水稻的高密度连锁图谱上，其中19个差异表达基因定位在Bala×Azucena、IR64×Azucena和IR1552×Azucena中至少两个群体共同的与根生长相关的QTLs区间，并用Southern杂交将其中的4个定位到IR1552×Azucena群体遗传连锁图谱相应的位点上。19个基因中的5个编码推断的未知功能蛋白质，其余14个编码已知功能蛋白，分别为膨胀素（Os-EXP2）、胚胎后期丰富蛋白、剪接体安装必需的SR相关蛋白（SART1）、自吞噬蛋白、碱性螺旋-环-螺旋转录因子、与ASR相似的果实成熟蛋白、镍结合蛋白、DNA结合蛋白、丙酮酸脱氢酶激酶、stomatins类蛋白、蔗糖调节蛋白SR1、液泡蛋白分类蛋白（VSP33a）、GA负调节因子、逆转座元件。

Anatomise configuration study showed that the adventitious shoot and somatic embryogenesis originated from surface layer cells of the calli fomed in hypocotyl organogenesis.

细胞学观察结果表明：不定芽和体细胞胚起源于胚轴形成的愈伤组织表层；不定根起源于愈伤组织内部。
