In the course of studies of the somatic chromosome configurations of the brain cells of Drosophila triauraria and D.auraria from 8 areas in China and some from Japan,it was found that in all of the species,the homologous chromosomes were in various degree of syna-psis,while the nonhomologes were distributed at random in the nucleus.There were detectably close synapses between homologous chromosomes during thellate prophase and early metaphase in mitosis of somatic cells.The frequence of synapses was-about 34%.However,no...

In the course of studies of the somatic chromosome configurations of the brain cells of Drosophila triauraria and D.auraria from 8 areas in China and some from Japan,it was found that in all of the species,the homologous chromosomes were in various degree of syna-psis,while the nonhomologes were distributed at random in the nucleus.There were detectably close synapses between homologous chromosomes during thellate prophase and early metaphase in mitosis of somatic cells.The frequence of synapses was-about 34%.However,no synapic pairing was found between X and Y chromosomes in the males.Herein,the so called "Rd values" were suggested (i.e.the relative distances between 2 centromeres of the homologous chromosomes of every pair) as a measure of chromosomal synapses in mitosis,and the visual observations fit well with the mathematical calculations.The occurrence of homologous chromosome synapsis in mitosis found among dipteral inserts as an exceptional phenomenon,and in other eukaryotes and even in higher plants and animals,as a general phenomenon,their evolutional significance was discussed.

对采自北京、上海等7个地区及来自日本的金色果蝇Ⅰ(Drosophila auraria)和金色果蝇Ⅲ(Orosophila triauraria)的三龄幼虫的脑神经节进行核型分析。发现在其有丝分裂的晚前期、中期阶段,4对同源染色体都在进行联会。联会发生的频率约为34%。XY染色体往往无联会的表现。常染色体联会时,各对染色体的常染色质区紧密靠拢,而着丝粒区则彼此稍有分开。 本文并提出了以每对同源染色体着丝粒距离的“R_d”值作为判断同源染色体联会的数量指标,通过随机取得的119个细胞的476个R_d值的分析,发现同源染色体联会频率与在显微镜下所观察的结果相吻合。 体细胞同源染色体联会,在双翅目昆虫的特殊现象和在真核生物及其他高等动、植物中作为一般现象的遗传进化意义,本文亦作了初步探讨。

The morphological differentiation of Discogobio is expressed in macro-structures and micro-structures. In the macro-structures, the differentiation showes the changes of sucking disc size that can be divided into two types. One type is the large sucking disc, whose posterior edge extend to or beyond anterior margin of eye vertically and width of central pad is equal to or larger than the diameter of eye; another is the small sucking disc, whose posterior edge does not extend to anterior margin of eye vertically...

The morphological differentiation of Discogobio is expressed in macro-structures and micro-structures. In the macro-structures, the differentiation showes the changes of sucking disc size that can be divided into two types. One type is the large sucking disc, whose posterior edge extend to or beyond anterior margin of eye vertically and width of central pad is equal to or larger than the diameter of eye; another is the small sucking disc, whose posterior edge does not extend to anterior margin of eye vertically and width of central pad is smaller than the diameter of eye. Although the macro-morphology differentiation of sucking disc of Discogobio seems related to environment where every species lives, actually it is only a superficial phenomenon. Because D. yunnanensis with large sucking disc and D. macrophysallidos with small sucking disc can be found simultaneously in rivers as well as lakes or pools. So the authors consider that types of sucking disc may be a clue of recording the differentiating history of Discogobio rather than a clue of recording their adaptation for varied niches. The two groups with different types of sucking disc are two natural groups who were derived from an ancestor. In the micro-structures, the differentiation is expressed in changes of papillae distribution and tentacle numbers at the top of papillae. Based on the results observed by scanning electron microscopy and ecological information of Discogobio, it is inferred that the distribution of papillae on disc and the tentacles at top of papillae are more connected with habitats of the fishes. When they evolved continually for adapting various environment, the two groups shown different ways in their micro-morphology. The development of large sucking disc group evolved mainly towards expanding distributive area of papillae on the central pad and increasing tentacle numbers at the top of papillae; in this group D. elongatus developed perfectly and more adapted swift current niches. The development of small sucking disc group evolved in two aspects respectively. One was of expanding distributive area of papillae on the central pad and increasing tentacle numbers at the top of papillae, so the adhensive ability of the sucking disc can be strengthened, such as rivers populations of D. macrophysallidos; another was not of strengthening the adhensive ability of the sucking disc, so the papillae on the sucking disc was scattered and with less tentacles and the ability of the fishes movement were developed by enlarging the diameter of eye and expanding the length of barbel, and D. longibarbatus is a representative. Therefore, the sucking disc morphological differentiation of Discogobio is a complex phenomena, which records the evolutionary history of Discogobio and adaptation of every species in the genus.
