Seeds of three varieties of groundnut were irradiated with gamma rays giving three mutants of white-vein with smaller leaflets (WVSL) than the parents. Populations derived from WVSL segregated into three kinds of phenotypes: (a) those like the initial parent, (b)the same as WVSL, and (c) the same as WVSL in vein color but smallest in stature with smallest leaflets of the three and no pod. The population segregated into a 1∶2∶1 ratio for normal: smaller: smallest in size of leaflets, a 3∶1 ratio for high: low...

Seeds of three varieties of groundnut were irradiated with gamma rays giving three mutants of white-vein with smaller leaflets (WVSL) than the parents. Populations derived from WVSL segregated into three kinds of phenotypes: (a) those like the initial parent, (b)the same as WVSL, and (c) the same as WVSL in vein color but smallest in stature with smallest leaflets of the three and no pod. The population segregated into a 1∶2∶1 ratio for normal: smaller: smallest in size of leaflets, a 3∶1 ratio for high: low stature, and a 1∶3 ratio for yellow: white veins, indicating a simple dominance or incomplete dominance inhereditary manner. The 3 characters were thought to be controlled by the same locus. It seems that chlorophyll content of the leaflets has no relation to the color of the veins, but has relation to the stature of plants.

研究了用Gamma射线辐照花生产生的叶片白叶脉、叶较小突变体后代的遗传。结果表明,叶片白叶脉、叶片较小突变体后代分离出3种表现型:①所有性状与辐照前原品种相同;②所有性状与叶片白叶脉、叶较小突变体相同;③叶片白叶脉、叶极小、植株极矮、不结果。相应3种表现型的分离比例为1∶2∶1。认为白叶脉、叶片大小和植株高度是由同一基因位点控制的。高株对极矮株为显性,分离比例为3∶1;白叶脉对黄叶脉是显性,分离比例为3∶1;叶片大小是不完全显性效应,分离比例为1∶2∶1。叶片叶绿素含量与白叶脉无关,但与株高有关。

Aim:To determine whether gamma irradiation influences phenotype of dendritic cells (DCs) in vitro.Methods:DCs were induced from the peripheral blood mononuclear cells (PBMC) with RPMI 1640 medium containing recombinant human GM CSF (rhGM CSF, 800 U/ml) and recombinant human IL 4 (rhIL 4, 500 U/ml). Phenotypic changes were monitored by light microscopy. Lipopolysaccharide (LPS) at a concentration of 5 mg/L was added into the cultures after 6 days of growth and the cells were cultured for another 24 hours...

Aim:To determine whether gamma irradiation influences phenotype of dendritic cells (DCs) in vitro.Methods:DCs were induced from the peripheral blood mononuclear cells (PBMC) with RPMI 1640 medium containing recombinant human GM CSF (rhGM CSF, 800 U/ml) and recombinant human IL 4 (rhIL 4, 500 U/ml). Phenotypic changes were monitored by light microscopy. Lipopolysaccharide (LPS) at a concentration of 5 mg/L was added into the cultures after 6 days of growth and the cells were cultured for another 24 hours for DC complete maturation. The harvested DC on the 7th day were equally divided into 2 parts.One part was used as non irradiated DC (naive DC),and the other part was transferred to a gamma irradiator and irradiated at a dose of 30 Gy (irradiated DC). Cell surface molecules were analyzed by flow cytometry.Results:Gamma irradiation reduced the expression of CD86, CD80,and HLA DR molecules on dendritic cells, especially CD86 molecules ( P =0.007 2).Conclusion:Gamma irradiation of dendritic cells influences phenotype of DC.
