Variation of chromosomes of pollen calli derived from anther culture and those of somatic cells of 54 plants was exmined. It was found that most of them were mixoploids, but according to the different basic number (x) of chromosomes, a great number of pollen wheat were haploid a homozygous diploid plants. Meanwhile, 5x plants and typical mixoploid plants with anther culture were obtained for the first time, and chromosome dicentrilization was observed in the pollen calli.Endomitosis, karyomixis, multipolar mitosis...

Variation of chromosomes of pollen calli derived from anther culture and those of somatic cells of 54 plants was exmined. It was found that most of them were mixoploids, but according to the different basic number (x) of chromosomes, a great number of pollen wheat were haploid a homozygous diploid plants. Meanwhile, 5x plants and typical mixoploid plants with anther culture were obtained for the first time, and chromosome dicentrilization was observed in the pollen calli.Endomitosis, karyomixis, multipolar mitosis and chromosome break of the somatic cells were easily induced by culturing in vitro and by pollen haploidy. These abnormal mitotic processes have caused chromosome doubling, the production of mixoploids and new forms of chromosomal variation.Studying the effect of the stage of pollen development on anther culture in vitro, and on the improvement of culturing conditions and methods may be possible to increase the frequency of pollen plants and spontaneous doubling, and obtain new forms of chromosomal and genome variation. It may be a new approach with potentiality to chromosome and genome engineering.

研究了用花药培养方法诱导出来的小麦花粉愈伤组织和54个当代植株体细胞染色体的变异情况。发现它们大多是混倍体,但根据其染色体基数的不同,大量的花粉小麦是单倍体和纯合二倍体植株。同时,我们还首次获得了用花粉培养诱导的小麦5x植株和典型的混倍体植株在花粉愈伤组织中观察到染色体双着丝化现象。 离体培养和花粉的单倍性容易引起植物体细胞的核内有丝分裂,核融合,多极有丝分裂以及染色体断裂等现象。这些有丝分裂的异常过程,是产生染色体加倍、混倍体以及染色体变异的各种新类型的重要原因。 研究花粉发育时期在花药培养中的作用,改进培养条件和方法,不仅可以提高诱导花粉植株和提高花粉植株自然加倍的频率,同时还可能获得染色体和染色体组发生变异的新类型,为研究染色体工程和染色体组工程开辟新途径。

Protoplast, isolated from mesophyll cells of tobacco (Nicotiana tabacum var. Copus yeusuheku No. 4) through a "one-step procedure" with the enzyme made in China, was cultured by means of liquid-thin-layer culture. About fourteen days later, the medium was supplemented with fresh liquid in the absence of mannitol, so as to dec-rease the osmotic pressure to half of the original level. Then, protoplast was transferred to a solid medium without mannitol. The small callus, 1-2mm in diameter, was transferred to the...

Protoplast, isolated from mesophyll cells of tobacco (Nicotiana tabacum var. Copus yeusuheku No. 4) through a "one-step procedure" with the enzyme made in China, was cultured by means of liquid-thin-layer culture. About fourteen days later, the medium was supplemented with fresh liquid in the absence of mannitol, so as to dec-rease the osmotic pressure to half of the original level. Then, protoplast was transferred to a solid medium without mannitol. The small callus, 1-2mm in diameter, was transferred to the differentiation medium for regeneration of the intact plant. The plantlet was transferred to a pot to grew.Comparisons of various components of media were carried out. It was shown that a little change of the content of two macroelements and the increase of lac-talbumin hydrolysate and certain organic substances, would accelerate the cell di-vision and increase the frequency from about 50% in NT medium as control, up to more than 80%. Budding and the effect of the condition on culture were discussed.

以普通烟草的一种香料烟品种为材料,用国产酶一步法游离叶肉原生质体。以液体浅层静置培养的方法培养原生质体,14天左右添加一次新鲜的不含甘露醇的培养液,使渗透压减半。以后转入完全没有甘露醇的固体培养基里。将形成的直径为1—2毫米的小愈伤组织转至分化培养基,再生了完整植株。而后将苗转至花盆里能正常生长。 比较了原生质体培养基的不同成分,发现将大量元素中两个成分的量略作改变,并增加水解乳蛋白及一些有机成分能加速分裂速度,分裂频率由对照NT培养基的50%左右提高到80%以上。讨论了出芽现象及培养条件对培养的影响。

1. The spontaneous firings of nucleus locus coeruleus (LC) were recorded. The presence of opiate receptors in these neurons was identified. They were facilitated by the natural pain stimulation, and inhibited by administration of analgesics such as morphine.2. The frequency of spontaneous firing of LC was increased by electrical stimulation of habenular nucleus (HN), and decreased after destruction of this nucleus.3. The frequency of firing of LC responded increasingly to microiontophoretically applied acetylcholine (ACh). But application of atropine, the blocker of ACh, decreased the frequency, and prevented the increasing effect of stimulation of HN, which increased the frequency of firing of LC. Microiontophoretical application of physostigmine in most cases increased it. We suggested that ACh might act as transmitter from HN to LC, so that the effect of increased firing of LC with the stimulation of HN was attributed to the increase of ACh release.4. The stimulation of habenular nucleus, perhaps through the intermediate neurons, facilitated the spontaneous firings of LC. Because the habenular nucleus was an important relay from the forebrain to brainstem, the forebrain could modulate the activity of LC through this pathway.

1.本文记录了蓝斑核等部位的单位自发放电,实验表明这些细胞可能含有阿片受体.它们可为自然痛刺激所兴奋,可被吗啡等镇痛剂所抑制。 2.电刺激缰核可以使蓝斑细胞的自发放电频率增高。损毁一侧缰核可使蓝斑细胞自发放电暂时性减少。 3.电泳乙酰胆碱使蓝斑核细胞放电增多.电泳阿托品使之减少,并可对抗刺激缰核所引起的蓝斑细胞放电增多反应。电泳毒扁豆碱一般能增加蓝斑细胞放电频率。电泳γ-氨基丁酸抑制蓝斑放电。可见刺激缰核引起蓝斑细胞放电增多是通过释放乙酰胆碱递质实现的。 4.刺激缰核(可能通过中间神经元)加强蓝斑细胞的自发放电。由于缰核是许多前脑边缘结构至脑干的重要驿站,故前脑可能通过缰核对蓝斑的活动进行某种调节。
