查询词典 embryogenic

Pale yellow, brown and white translucent calli were produced from zygotic embryos which were stored at 4 to 6℃ for 1 to 3 months and then cultured on medium LP+2mg/L 2, 4-D+1mg/L 6-BA in the dark for one month. Only white trenslucent calli were embryogenic.

合子胚在4～6℃低温条件下保存1～3个月后，接种于LP+2mg/L 2，4-D+1mg/L 6-BA的培养基上，黑暗条件下培养1个月后，产生浅黄色、褐色和白色半透明三种愈伤组织，其中白色半透明愈伤组织是胚性愈伤组织。

Segments produced clusters of somatic embryos from embryogenic calli or directly from root apical meristems , and that also can convert into bud directly in the different tissue culture conditions. Modified media B5 with 1.0 mg.L-1 2,4 - D and 3.0mg.L~1 6-BA is suit to induce calli, and 0.5 mg.L-1 NAA is fit for somatic embryos inducement from calli. 6-BA encreased direct somatic embryogenesis on root tip distinctly,but NAA is retard it. NAA also prolong the time of root-tip convert into bud directly.

在改良B_5(微量元素为原来的1／3)中加入1.0mg.L~(-1)2，4—D和3.0mg.L~(-1)6-BA对离体根尖的愈伤组织诱导较为合适，0.5mg.L~(-1)NAA有利于从愈伤组织上产生体细胞胚；6-BA明显促进离体根尖直接产生类原球茎，而NAA则有阻碍作用；同时NAA的存在也使离体根尖直接成芽的时间延长。

The development of the calli and single few-celled aggregates was observed through paraffin sections.The results revealed 5 pathways of embryogenic calli origination including origination from both ends of hypocotyls,origination in inner,differentiation from non-embryonic cells,origination from outer cells of calli,and origination in the surrounding of gland.

以陆地棉品种Coker 201下胚轴为外植体诱导愈伤组织，并以介于30-50目筛之间的胚性愈伤细胞团为材料进行单个细胞团培养，采用石蜡切片法观察棉花愈伤组织诱导和分化过程及体细胞胚发生和发育过程。

The results showed that the carrot of different genotypes responded differently with the plant growth regulators. There was no significant difference on the three kinds of callus inducing medium for cultivar Linfeng. In contrast, the rate of embryogenic callus and the number of resistant plants in cultivar Japanese black filed five inch was raised with increasing plant growth regulator concentration.

结果显示：不同基因型胡萝卜的分化对激素浓度的反应不同，林丰改良五寸参在3种培养基上的胚性愈伤率差异不显著；日本新黑田五寸参胚性愈伤率和每个外植体分化的抗性株数随激素浓度的提高而呈上升趋势，2，4-D和6-BA浓度为1.0mg/L时胚性愈伤率和每个外植体分化的抗性株数最高，分别为87.50%和59株；日本新黑田五寸参以bar基因为标记基因、PPT作筛选剂时，分化较好。

The embryogenic calli were induced from immature embryos of 9 combinations of maizes.

用9个组合的玉米幼胚为外植体，诱导出胚性愈伤组织。

Somatic embryogenesis usually suffers an dedifferentiation process in which some somatic cells are transitted to embryogenic cells from vegetative cells.

体细胞胚发生一般经历一个脱分化过程，即由营养生长的体细胞转变成生殖生长的胚性细胞。

NAA mixed with 2,4-D was more beneficial to the formation of embryogenic callus. NAA has large promoting effect on callus germination culture of Xanthoceras sorbifolia at some concentration.

结论］NAA和2，4-D混合使用有利于胚性愈伤组织的形成；一定浓度的NAA对文冠果愈伤组织萌芽培养有较大的促进作用。

Among 33 genes in this study,25 were selected from a cotton somatic embryogenesis SSH array, considered differential expressed at different development stages such as the formation of embryogenic callus and somatic embryogenesis,the others including 5 SERK genes and 3 CKⅡgenes were acquired from the Genebank.

在所研究的33个基因中，有25个来自一个棉花的体细胞胚胎发生的SSH文库，这些基因在棉花胚性愈伤和各时期胚状体中有差异表达，另外5个SERK基因和3个CKⅡ基因来源于相关Genebank库。

Longan1 expressed from the embryogenic callus stage to the globular embryoid stages. Longan2 expressed in the whole process of longan somatic embryogenesis, which was probably a housekeeping gene. Longan3 expressed from the globular embryoid stage to the torpedo-shaped embryoid stage. Longan4、longan4'expressed only at the cotyledonary embryoid stage.

碱基序列分析表明，longan1在3'端存在一个开放阅读框，longan2、longan3分别在5'端存在一个开放阅读框，longan1在3'方向，longan2、longan3在5'方向均没有终止密码子，所以可能往相应的方向延伸仍为各自的ORF，因此可以通过RACE或者筛选cDNA文库的办法来获得它们的全长cDNA。
