查询词典 gametophytic

The arm repeat-containing 1 (ARC1) and the skp1-cul1-F-box proteins, belonging to the family of E3 Ub ligases, function in both the sporophytic and gametophytic self-incompatible responses, respectively.

自交不亲和反应也正是通过此途径实现的，ARC1(arm repeat containing 1)和SCFs (skp1-cul1-F-box-proteins)作为E3s分别在孢子体自交不亲和和配子体自交不亲和反应中起作用。

Nutrient cells were obtained from these pigment mutants by enzymatic method and conchocelis were got by parthenogenesis. When the conchocelis were mature and conchospores were released, they were cultured singly and picked up as F1 gametophytic thallus.

通过酶法分离突变体的营养细胞，单性生殖获得丝状体；分别使丝状体成熟并放散壳孢子，然后单株培养和筛选获得褐黄、翠绿和褐绿色子代叶状体。

The inheritance of poly-eggs was investigated by crossing and reciprocally crossing APIV with monoembryonic rice variety IR36,Minghui No.77 and Longtepu B,respectively.It was suggested that the production of poly-eggs is probably controlled by gametophytic genotypes,rather than sporophytic ones.

通过多胚水稻品系APⅣ与单胚水稻品种IR36、明恢77和龙特浦B正反杂交，研究APⅣ的多卵遗传行为，表明APⅣ的多卵性状可能不是由孢子体基因型决定的，而是由雄配子体基因型决定，属配子体遗传的范畴。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

坛紫菜野生丝状体经一定剂量60Co-γ射线辐照后，子代叶状体发生了变异，经大量培养后筛选出紫色突变体（3号Ⅰ）和经济性状优良的个体（7号Ⅰ和7号Ⅱ），通过体细胞酶解和单克隆技术快速获得诱变选育纯系，并对其主要经济性状进行了研究。

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。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
