  unisexual
Genetic Instability of (GATA)n Microsatellite DNA Repeats and Somatic Mosaicism in the Unisexual Lizards Darevskia unisexualis
      
A Unique Diploid-Tetraploid Unisexual-Bisexual Fish Complex (Pisces, Cobitidae)
      
Two parthenogenic families of unisexual species of Caucasian rock lizards of genusLacerta, L.
      
The genetic relatedness of several bisexual and of four unisexual "Lacerta saxicola complex" lizards was studied, using monomer sequences of the complex-specific CLsat tandem repeats and anonymous RAPD markers.
      
This idea is supported by the results obtained with RAPD markers; i.e., unisexual species genomes include only the loci characteristic of certain bisexual species.

The present study aims to observe (1) sex influence of the host on the development of male and female worms and (2) the effect of the normally developed and copulated males and females on the development of the unpaired worms. For this purpose, mice of different sexes were infected with either male or female cercariae and were killed at definite intervals after infection. The size of worms collected was measured and the condition of the development of sex organs was also observed. Another group of mice was infected...

The present study aims to observe (1) sex influence of the host on the development of male and female worms and (2) the effect of the normally developed and copulated males and females on the development of the unpaired worms. For this purpose, mice of different sexes were infected with either male or female cercariae and were killed at definite intervals after infection. The size of worms collected was measured and the condition of the development of sex organs was also observed. Another group of mice was infected with more female cercariae and less male cercariae while a third group, vice versa. Similar observations were made at definite intervals as in the first group.It was found that the sex difference in the host bore definite influence on males in the portal circulation, but this was not so evident on females. The development of the unisexual males in the male host was more rapid than in the female host. Female worms in the female host were only slightly bigger than in the male host.Mature males and females in copula did not hasten the normal development of the unpaired males which were only slightly larger than those in unisexual infection, but definitely smaller than those in copula. On the contrary, worms in copula seemed to exert an inhibitory action on the unpaired females which were definitely smaller than the females in unisexual infection.The copulation of male and female worms was permanent in character. It did not seem that male schisrosomes would change their partners. One male could only hasten the development and matura:ion of only one female.

1.单性感染之雌性日本血吸虫平均不超过5.35±0.07毫米,只为复性感染中成熟雌虫长度之1/3左右,且其生殖器官始终呈童雏状态。单性感染之雄虫能发育成熟,贮精囊内也有活动精子,但其大小与成熟合抱之雄虫平均相差3.05毫米左右。 2.宿主性别之不同对于血液中的雄性血吸虫有比较显著的影晌。在雄性宿主体内单性雄虫比雌性宿主体内之单性雄虫发育快。宿主性别之不同对于单性雌虫之影响则不甚明显,雌性宿主体内发育之雌虫仅略大于在雄性宿主体内之单性雌虫。 3.血液中合抱成熟之雌虫及雄虫的分泌物质不能促使未合抱之雄虫发育正常。未合抱之雄虫似略大于单性感染之雄虫,但是显著小于合抱雄虫。 4.合抱成熟之雌虫及雄虫的分泌物质对于未合抱之雌虫完全没有促使发育的作用。相反地,有一定的抑制作用而使未合抱之雌虫显著地小于单性感染之雌虫,二者之生殖器官皆停留于雏形状态。 5.复性感染中每对雌雄成虫之抱合是永久性的。每一条雄虫只能促使一条雌虫发育成熟而不再转换抱合其余未成熟之雌虫。 6.鉴于雌雄合抱对于日本血吸虫正常发育的必要性,故就生物进化之观点讨论了日本血吸虫雌雄异体的原始性。

In present work. morphological characters of flowerg in Ramie was observed in detail. It was discovered that under natural condition is a wide range of variation of flowers.The diversified variation is seldom seen among other plants within the same species.As for the rule of evolution of flowers, it is considered in present article that the most primitive flowers of Ramie were digenous consisting of a large number of components. Originally the initial forms of flowers had no se ual difference and showed common characters genetically.It was not until later that a variety of flowrs occurred because of the influence of exterior factors. The present flowers with many components show the atavism of their initial character, while the decrease in number of component of flower and the occurrence of unisexual flowers are the manifestation of evolution.

通过对苧麻花的形态学特征进行详细观察,发现在自然条件下,花的变异丰富多样,在同种植物中是少见的。对于花的演化规律,作者认为苧麻最原始的花为两性花,原始型的花具有大量数目的成员。花的原始体,最初尚无雌雄性别之分,在遗传上具有共同的特性,以后由于外界因素的影响,才出现各种类型的花,其中具6—8个花被,6—8个雄芯和2个雌芯的花是属原始性一种返祖现象,而花的各部数目的减少,以及单性花则是进化的表现。

The atavistic spikelets of Carex dabteensts not only have the bisexual structure, but also manifest a successive series in the reduction of spikelets. The discovery of the atavistic spikelets may prove that a unit of utricle is a turespikelet of Carex, and exhibites further the interrelationship between Schoeno Xiphtum, Kobresia and Carex. It is possible to believe that the Carex can hardly be derived from the Schoenoxphium, and to regard that they are the branches springing from a common ancestor, "the so-called...

The atavistic spikelets of Carex dabteensts not only have the bisexual structure, but also manifest a successive series in the reduction of spikelets. The discovery of the atavistic spikelets may prove that a unit of utricle is a turespikelet of Carex, and exhibites further the interrelationship between Schoeno Xiphtum, Kobresia and Carex. It is possible to believe that the Carex can hardly be derived from the Schoenoxphium, and to regard that they are the branches springing from a common ancestor, "the so-called Proio-Carex". The branches show the process of the reduction of spikelets, one from the bisexual spikelets of Schoenoxfphum and Kobresia to the unisexual spikelet of Uncna; and the other from the bisexual spikelets of old Indocarex to Eucarex, and then to Prmocarex. The evolutionary tree given in Fig. II shows the phylogenetic interrelationship between Schoenoxphum, Kobresa and Carex of the Carcodeae.

大别苔(Carex dabieensis)的返祖小穗不■两性结构,而且还表现出一个小穗减退的连续系列。大别苔的发现证明了苔草的果胞是一■,同时进一步揭示了Schoenoxiphium属、嵩草属(Kobresia)和苔草属(Carex)■缘关系,可以认为苔草属是很难起源于SchoenoxiPhium属,而它们可能是由一个称谓“■(Proto—Carex)”的共同祖先发出的分枝。这些分枝显示出小穗退化的过程,一个是从■noxiPhium属、嵩草属的两性小穗到钩轴莎属(uncinia)的单性小穗,另一个是从古■苔的两性小穗到苔亚属(Eucarex),再进一步发展到单穗苔亚属(primcocarex)。图Ⅲ■草亚科(Caricoideae)中Schoenoxiphium属、嵩草属和苔草属的系统发育的亲缘关系。
