ジャーナル フリーChymochromic pigments in twenty-five color forms of common portulaca dividing into eleven color groups and their F1 hybrids were studied by paper-chromatographic and spectrophotometric experiments.
Ten pigments of betacyanins (Bc1 to Bc5) and betaxanthins (Bx1 to Bx5) were chromatographically separated in various color forms of garden portulaca. Most of the flower colors were estimated by qualitative and quantitative differences of chymochromic pigments.
In general, the purple components, Bc3 and Bc4, predominantly appeared in most of F1 hybrids, while the yellow components, Bx1 and Bx2, did not appear in F1 hybrids. Therefore, betacyanin were, in general, dominant over betaxanthin.
On the other hand, the higher content of betacyanin in purple color form is dominant to the lower content of betacyanin in pink form, and the higher content of betaxanthin in yellow orange form is recessive to the lower content of betaxanthin in pink form in F1 hybrids. In some F1 hybrids, however, the pigment content is nearly intermediate between the contents of both parents. White color form containing neither betacyanin nor betaxanthin is recessive to all the colored forms examined.抄録全体を表示PDF形式でダウンロード (2989K) -

ジャーナル フリーThe genetic differences in the competence of the donor to affect splenomegaly in GVH reactions were studied. The degree of splenomegaly induced by N strain donors was higher than that induced by C strain donors in White Rock embryo hosts which have quite different alleles at the B blood group system from both donor strains. F1 and F2 donors induced splenomegaly of a similar degree to that induced by C strain donors. NBc donors induced larger spleens than did CBc donors. Similar tendencies were observed when New Hampshire embryos were used as hosts. These results indicate that there are genetic differences in the competence of donors of these two strains.
Association of the B locus alleles of the donors with the degree of splenomegaly was found. The effect of the BA allele was generally stronger than the BG allele and the BI allele was of intermediate effect. Similar effects were also observed when blood-grouped White Leghorn embryos were used as hosts. It is suggested that a considerable part of the strain differences found would be brought about by the differences between alleles at the B locus in the donors.抄録全体を表示PDF形式でダウンロード (717K) -

ジャーナル フリーThe chromosomes of Phyllobius longicornis Roelofs collected from three localities in Hokkaido were studied in male germ line. The present species showed two forms which differ in their chromosome number: 10+Xyp and 11+Xyp. In Mt. Moiwa population, the occurrence of the former form is 84.4 per cent, while that of the latter is 15.6 per cent.抄録全体を表示PDF形式でダウンロード (451K) -

ジャーナル フリーSegregation Distorter (SD) was found to assort more frequently with the Y-chromosome in SDcn/SD+; XYY males of Drosophila melanogaster. Because gametic and zygotic selection can be eliminated as possible explanations of this non-random assortment, it is suggested that the pairing pattern in the sex chromosomes is changed when segregation distortion occurs. The hypothesis of homology between the SD region and part of the X-chromosome suggested by Hiraizumi and Nakazima (1967) could be one possible explanation.抄録全体を表示PDF形式でダウンロード (646K) -
