不育

The near isogenic lines, Ps and Pf, were developed by anther, which serves as materials for isolating and cloning Rf3 gene by using of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) we had improved in this study.

该特异蛋白质点的出现与消失可能与玉米CMS-S的育性恢复有一定关系，对其纯化分离将为Rf3基因的克隆奠定基础和进一步了解玉米质核互作不育表达模式的分子机制。

The research results indicated that in the genetic background of weak photo-sensitivity of flowering, photoperiodic sensitive genic male sterility and fertility restoration were controlled by two sep...

结果表明，在弱感光型遗传背景下光敏不育性及其育性恢复受两对独立的细胞核隐性主基因控制和修饰基因的作用。

Correlation analyses on the contents and ratios of endogenous hormones with selfing fertilities showed that selfing fertility was not determined only by one single hormone level, but partially affected by the joint action or balance of several hormones in Nongken58S original and untransformed regenerant controls under long-day. Our results did not support different already proposed hypotheses on one single hormone action in fertility expression of PSGMS rice.

1通过对因受环境低温影响而在长日条件下不育性部分逆转的原始材料和组培再生后代材料的自交结实率与内源激素水平及比值相关性分析表明，农垦58S育性转换并非取决于某种单一激素水平的改变，而可能与多种激素的共同作用和平衡关系有关，从而说明&众说纷纭&的单一激素作用的假说难以成立。

The segregational proportions differ from the Mendelian mode in which selfed progenies of recessive individuals do not segregate.

湖北光敏感雄性不育水稻从1973年发现l'}至今已有15年f，最高世代已进入20代以上，育性仍在分离之中。

In the anthers of China CMS lines,there is normaldifferentiation of anther walls,male sterility is characterizedby the abortion of sporogenous cells and microsporemother cells.

我国棉花细胞质雄性不育的败育时期主要集中在造孢细胞增殖时期和花粉母细胞减数分裂时期。

The results showed that the labastrums and the anther of staminate flower of the material were no difference comparing with these of other materials in early stage.

结果表明，西瓜S29雄性不育材料的花蕾及花药在初期的发育与雄花可育的其他材料相比基本一样。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。

Experimental results show that there are existing some indifferent mechanisms to the pollen sterilization of the Ms types: during the period of single nucleic to three nucleic pollen cell,we observed that the cell of xylem and phloem in anther septum abnormally developed,also the cell in the sheath of vascular bundle,smaller and arranged irregularly; the metabolic block developed too,es...

结果表明，不育类型的花粉败育有着一些共同的机理：在花粉单核期至三核期可见到花药隔维管束的木质部及韧皮部细胞发育较差，维管束鞘细胞发育不良，体积较小，排列紊乱；在单核花粉期至三核花粉期均发生物质代谢障碍，特别在花药部位尤为明显；由于维管束发育不良和花药物质代谢障碍，导致了花粉缺乏营养而败育。

In different nuclear background materials, except for the 1st editing site of 48-2, editing frequency of sterile cytoplasms was all lower than that of fertile cytoplasms.

在不同核背景材料中，除48-2材料的第1位点外，不育胞质的编辑频率均低于可育胞质的编辑频率。

All of the sterile pollens possessed malfunctioned exine.

不育花药中的Ca2+在花药发育的各时期均比可育花药要多。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.
