查询词典 progenies

Auricularia auricula is of the single-factor controlled mating system according to mating test among the F1 progenies and their parents, combining the method of dyeing the nuclei of the mycelia and observing the nuclear phase under the fluorescence microscope and the method of observing the clamp connection under the light microscope to determine whether the dikaryotic mycelia were formed.

摘 要：从黑木耳种内杂交子H2J3的子实体上单孢分离培养得到F1代52个单核体菌株，将F1子代及亲本(H2，J3)等所有供试单核体菌株的菌丝体两两配对培养，采用核荧光染色观察核相，和光学显微镜观察锁状联合，鉴别菌丝交配反应是否形成双核体菌丝，同时测定了亲本菌株所有F1子代的交配型。

The novel restorer line Nsa restorer-1 and its progenies were analysed by genomic in situ hybridization combined with double-colour fluorescence in situ hybridization technologies, the results showed that Nsa restorer-1 was Brassica napus-Xinjiang wild Sinapis arvensis disomic alien addition line,consisting of the whole genome of Brassica napus and a homologous chromosome pair of Xinjiang wild Sinapis arvensis.

用基因组原位杂交(genomic in situ hybridization， GISH)结合双色荧光原位杂交(double-colour fluorescence in situ hybridization， dc-FISH)技术，对甘蓝型油菜新型恢复系Nsa恢1及其后代进行了研究，结果表明，Nsa恢1为甘蓝型油菜-新疆野生油菜二体异附加系，包含了甘蓝型油菜全基因组和新疆野生油菜1对染色体，这1对新疆野生油菜染色体为同源染色体。

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。
