There are about 8 species of sturgeons in China. In the Yangtze, theChientang, the Zhujiang, the Amur, the Irtish and the lli River, all occursturgeons. The Yangtze Rivet falls into the Yellow Sea and the East ChinaSea. The gross area of both seas is 1.15 million km~2, which are a very broadwater-zone for migration-sturgeons graze. So the Yangtze River has the grea-test potence of developing sturgeon fishery. In the Northwest Area, thearea of saltwater lakes takes up 55% of the gross area (80000km~2) of...

So the Yangtze River has the grea-test potence of developing sturgeon fishery. In the Northwest Area, thearea of saltwater lakes takes up 55% of the gross area (80000km~2) of thelakes in China, and there are many large reservoirs above ten-thousand mu.All these are suitable for the transplantation and acclimatization for sturge-ons. If we actively take the measure of artificial propagation of sturgeonsto develop their fishery, the sturgeons output of our country will probablygo ahead of the world.

A human promyelocytic leukemia cell mutant (HL-60-AR) with characteristics of resistance to 8-azagunine and deficient in hy-poxanthine and guanine phosphoribosyltrans-ferase had been established from HL-60 cell line in our laboratory.The previous study showed that HL-60-AR mutant cells main-tained the basic biological characteristics and potence of differentiation induced by various compounds of their parental HL-60 cells.In order to investigate the dependence of inducer presence for HL-60-AR cell differentiation,the present experiment was designed that HL-60-AR cells were washed for 3 times to re-move inducer after treatment for various pe-riod,and suspended in medium without indu-cer,then assayed expression of cell differen-tiated characters.Meanwhile,the cultures in which inducer was removed were passaged se-veral generations and assayed to determine the passage hereditary stablization of cell dif-ferentiated characters. Experimental results showed that when HL-60-AR cells incubated in medium without inducer after they had a previous treatment with 10~(-6)M RA for 24 hours,the cell dif-ferentiated characters could be continuous ex-pression and the number of differentiated cells was progressively increased.The increase of NBT reduction positive cells and cell mem-brane C_3 complement receptor positive cells de-tected by YC rosette formation was indepen-dent on the duration of incubation between cells and RA,but it does depend on the ad-ditive duration of cell exposure to RA-contai-ning medium and RA-free medium.The cells which exposed to RA for 24 hours and rein-cubated in RA-free medium for another 120 hours showed kinetics of numbers of differen-tiated cells similar to cells exposed RA for 144 hours (Fig.3,4).This result indicated that cellular commitment to differentiation re-quired an approximately 24 hour exposure to RA.Following this,committed cells continued to differentiate.However,cell differentiated characters induced by DMSO was unstable and reversible. A notable result happened when RA-induced cells were suspended in conventional culture medium and passaged for 3 times,the number of differentiated cells could be de-tected as high as 50 percent.Taken togather the results indicate that after exposure to RA for 24 hours,a significant cell differentiation could be required and cell in populations re-moved from RA thereafter continued to diffe-rentiate.The expression of differentiated cha-racters was irreversible and heritable,exten-ding from parent to daughter cells. It was showed that a cell proliferative arrest could be assayed as HL-60-AR cell dif-ferentiation.The differentiated cells decreasedcell DNA synthesis and number of colony-forming in soft agar medium,and lost the ability of tumor-producing in nude mice.A rapid decrease of c-myc oncogene expression detected by molecular hybridization at the ear-ly stage of RA-treatment indicated that the inhibition of c-myc gene expression might provide some clues for explaining the primary-process and molecular mechanism of HL-60-AR cell differentiation.

HGPRT~-人早幼粒白血病细胞突变株(HL-60-AR)与RA保温一定时间后,洗去药物继续培养,细胞分化性状(NBT还原能力、细胞膜C_3补体受体及形态变化)不但继续存在,而且能持续表达。撤去RA后连续传代培养,至少在传三代后细胞分化性状仍高度表达。然而,DMSO对HL-60-AR细胞的作用特点明显不同于RA。HL-60-AR细胞分化伴随增殖能力的降低。核酸分子杂交结果表明,细胞c-myc癌基因表达受抑先于细胞分化性状的获得和增殖能力的下降。

The F1 plants from 13 reciprocal crosses showed significant differences in chalkiness of rice Kermis when the parental difference reached a certain extent, and kernels pro luced by an F1 plant were less chalky when the female parent was less chalky. In the segregating populations, chalkincss of kernels was frequently correlated positively to 100 grain weight and grain width, and nagetivcly to grain length, the ratio of grain length to width and percentage of brown rice.

The F1 plants from 13 reciprocal crosses showed significant differences in chalkiness of rice Kermis when the parental difference reached a certain extent, and kernels pro luced by an F1 plant were less chalky when the female parent was less chalky. In the segregating populations, chalkincss of kernels was frequently correlated positively to 100 grain weight and grain width, and nagetivcly to grain length, the ratio of grain length to width and percentage of brown rice. A number of variants exceeding higher parent in chalkincss were found in 3 F2 populations. Backcrossing might have low efficiency in improving chalkiness when higher chalky parent was used as female.Estimates of broad sense heritability of clialkiness were moderate in 3 crosses. Chalky differences between female and male in 3 crosses were controlled, respectively, by 1 to 3 groups of incompletely dominant genes with different overall dominant directions showed by their potence ratios. It is possible to improve chalkiness of rice kernels by using less chalky varieties as the female parent, enlarging F2 population and increasing the intensity of selection.

13个籼稻杂交组合的研究表明,垩白差异较大的亲本间,其正反交F_1的垩白度存在显著差异,以垩白度较低的品种作母本,其垩白度较低,3个杂交组合分离世代群体中,垩白与百粒重及谷粒宽呈极显著正相关,与谷粒长、谷粒长宽比以及出糙率呈显著或极显著负相关,F_2群体中出现大量正向超亲(高于高垩白亲本)的变异.以垩白度较高的材料作母本回交改良垩白度的效率较低,垩白度具有中等大小的广义遗传率.不同组合中亲本垩白度的差异分别由显性方向不同的1~3组部分显性的基因所控制,要改良稻米垩白,应选择垩白度较低的材料作母本,同时扩大分离世代的种植群体,提高选择强度.
