ジャーナル フリー1. 筆者の創案による蛋白分解酵素•ナイルブリューサルフェート法と各種の有機溶媒への浸漬とを併用してハツカネズミの肝臟細胞, 膵臟細胞及び脊推神經節細胞内のゴルヂー物質の溶解性を檢べた。その結果によると大體に於いてゴルヂー物質にはトリプシンに消化される蛋白質とアセトン可溶のリポイドが基礎物質として含有され,而も或種の結合状態にあることが推定された。
2. ゴルヂー物質に含まれるリポイドがアセトンに可溶である事實はゴルヂー物質にはレシチンが存在せぬことを示してゐる。
3. 肝臟細胞及び脊推神經節細胞内のゴルヂー物質のリポイドは全くレシチンを含有せぬが膵臟細胞のゴルヂー物質には少量のレシチンが存在するらしい。此の事實は各組織細胞によつてゴルヂー物質を構成する成分に多少の變異があることを示唆してゐる。抄録全体を表示PDF形式でダウンロード (1948K) -

ジャーナル フリーIn this report two rare pattern types: distincta (new name proposed by Prof. T. Komai) (Fig. 1-a, b) and rostrata (new name proposed by Prof. T. Komai) (Fig. 1-c, d) are dealt with. Both of these are due to the factors (PD=factor for distincta, PR=factor for rostrata) belonging to the same allelomorphic series as succinea, axyridia, spectabilis, conspicua, forficula, transversifascia, aulica and gutta and behave as dominants to succinea, but the heterozygote of distincta and succinea and the heterozygote of rostrata and succinea often can be distinguished from the respective homozygotes in that the spot has a concavity on the posterior side (Fig. 1-b, d). The concavity, however, is missing in some cases, and the heterozygote may show the same appearance as the homozygote (Fig. 1-a, c).
Distincta is completely dominant to forficula and rostrata. The heterozygote of distincta and axyridis (PDPA) resembles the heterozygote of conspicua and axyridis (see Report II, Fig. 1-l, m), but can be distinguished from the latter by the presence of the antero-median spot of axyridia (Fig. 2-c). All of the heterozygotes of conspicua and distincta (PCPD), gutta and distincta (PGPD), distincta and spectabilis (PDPS), distincta and transversifascia (PDPT) and distincta and aulica (PDPAu) have phenotypes similar to distincta, except that the antero-median spot is entirely missing (Fig. 2-d).
Rostrata is completely dominant to forficula. The heterozygote of rostrata and axyridis (PRPA) resembles the heterozygote of spectabilis and axyridis (see Report II, Fig. 1-h, i), but can be distinguished from it in the presence of the antero-median spot of axyradia (Fig. 2-g). The heterozygotes of spectabilis and rostrata (PSPR) and rostrata and aulica (PRPAu) cannot be distinguished from the heterozygote of spectabilis and forficula (Fig. 2-h). The heterozygotes of conspicua and rostrata (PCPR), gutta and rostrata (PGPR) and transversifascia and rostrata (PTPR) cannot be distinguished from the heterozygote of conspicua and forficula (Fig. 2-i).抄録全体を表示PDF形式でダウンロード (804K) -

ジャーナル フリー1. 常型 (AABB) 矮型 (aaBB) に屬する玄米の鞘葉の生長を其先端に於ける生長素形成及びヘテロアウキシン稀薄溶液に依る生長促進の二つの立場から檢討した。
2. 30°C, 飽和濕度, 暗所で育成した鞘葉に就て其先端 2mm に於ける生長素形成をAvena test に依り測定した結果に依ると, 稻の鞘葉先端の生長素形成能は鞘葉の年齡の増加と共に急激に下降し, 發芽7日目では實際的に認められぬ程度になる。
3. 發芽の經過に伴ふ鞘葉の生長素形成能の低下は常型よりも矮型に於ける方が明かに急激である。且つ後者では或時期に有效生長素量の減退が起る樣である。
4. 發芽前に種々の濃度のヘテロアウキシン溶液に30時間浸漬した結果に依ると,稻の鞘葉の生長は液の濃度が適度の場合には促進され (約0.0025%), この濃度を遠ざかるに從ひ抑制される。
5. 最適濃度に於ける生長増加の割合は常型よりも矮型に於ける方が明かに顯著である。この事實は既述の鞘葉先端に於ける有效生長素形成量の兩型間に於ける相違と何らかの關係があるものと考へられる。抄録全体を表示PDF形式でダウンロード (1515K) -

ジャーナル フリーThe present paper deals with the chromosomes in the male germ cells of the following six species belonging to the Locustidae (Orthoptera). The numerical relation of the chromosomes existing in these species is given in the following table. The morphological features of chromosomes may be clear by reference to the accompanying figures (Figs. 1-32).抄録全体を表示PDF形式でダウンロード (572K) -

ジャーナル フリーOn the grouping of gene mutations in Drosophila melanogaster, two cases are conceivable, namely, (1) grouping in one male, and (2) grouping in one chromosome. Although the present writers have met with examples for both of these cases, which were induced by neutron radiations from a cyclotron, the question whether or not the grouping is the characteristics of the neutron irradiation was not decided. The object of this experiment was to see whether X-rays also give rise to simultaneous occurrence of gene mutations in one male as well as in one chromosome. Unfortunately, an accident during the experiment prevented us from obtaining result from our study on (1), grouping in one male, so that only the case (2), grouping in one chromosome, can be dealt with here.
As to the procedure of the experiment, the ordinary “ClB” method for sex-linked lethals was used and the F2 maleless culture, which is regarded as the result of the presence of a lethal or lethals located in the treated X-chromosome, was carried to the next F3 generation. By inspecting the sex-ratio in the F3 offspring, it is possible to determine approximately whether the lethal mutation is either one in one chromosome or many in one chromosome, although by this method the detection is possible only when two or more lethals are situated so far apart from one another that a fairly large number of crossing over can take place between them.
In this way, out of 17 F2 maleless cultures induced by X-rays (rejecting the remaining 10 cultures with unreliable data) there was no case with two or more lethals per chromosome, whereas in our previous work in which neutrous were used, out of 18 F2 maleless culture tested there were 8 samples with two or more gene mutations in thee same X-chromosome.
Added in the proof. According to our second experiment recently repeated with X-rays 3000r in intensity, we found that “grouping in one male” could be also raised with X-rays. On the other hand however, “grouping in one chromosome” was also observed with extremely high rate (ca. 85 per cent). In view of the results described in this paper, it is difficult to understand such results and we are now going to repeat the experiment once again.抄録全体を表示PDF形式でダウンロード (428K) -
