F〓 of transgenic allotetraploid fish containing"all-fish"transgene——pCAgcGHc was obtained respectively by inbreeding and gynogenesis. Positive rate of pCAgcGHc detected by PCR was 90% in F〓 of transgenic allotetraploid fish produced by inbreeding, while most F〓 of transgenic allotetraploid fish produced by gynogenesis showed diploidy measured by flow cytometer. The results above imply that developing the pure line of transgenic allotetraploid fish through inbreeding is feasible, but the operation should be modified if gynogenesis is introduced.
采用近交和雌核发育方法培育出转pCAgcGHc基因异源四倍体鲫鲤F〓代,通过PCR检测,外源基因pCAgcGHc在近交转pCAgcGHc基因异源四倍体鲫鲤F〓中的整合率为90%,而流式细胞技术检测雌核发育转pCAgcGHc基因异源四倍体鲫鲤F〓的倍性多为二倍体,说明通过近交筛选转基因异源四倍体鲫鲤纯系的方法是可行的,但是通过雌核发育来筛选转基因异源四倍体鲫鲤纯系还要就方法上进一步的改进。

Climatic gradients were based on data sets from 841 meteorological stations throughout China. Definitions for floristic distributional patterns were based upon the work of Prof. Z. Y. Wu. Most of these floristic distributional patterns were strongly correlated with the geographic gradients in climate, except for cosmopolitan, cultivated and invasive genera. Tropical genera form a large fraction of the total genera (ranging from 0.84% to 94.38% in the regional floras) with the highest proportion in southern Yunnan and Hainan Island. Tropical genera occur predominantly in southern China of 0° N latitude and decreased with increasing latitude, as would be expected. Interestingly, the disjunct Tropical Asia and Tropical America distribution were not restricted to southern latitudes. Temperate genera account for 5.1% to 98.83% of the total genera in regional floras with the highest proportion in the province of Xinjiang. Most of these genera followed geographic gradients in climate as expected (temperate genera conspicuously dominate the landscape at higher latitudes), except the East Asian and North American disjunct distribution, Eastern Asian distribution and Chinese endemic distribution. Generally, most plant genera demonstrated some correlation with climatic and geographic gradients. The most important gradients were those of annual air temperature and precipitation. A small fraction did not demonstrate significantly particular pattern:"Cosmopolitan","East Asian and North American disjunct","Eastern Asian" and "Chinese endemic" distributions. The North Temperate distribution had the highest correlation with mean annual air temperature and precipitation.
结果如下:(1)除世界分布、栽培和入侵成分外,大部分中国种子植物属的地理成分的分布与地理相关密切;(2)热带分布属(泛热带分布、热带亚洲至热带美洲间断分布、旧世界热带分布、热带亚洲至热带大洋洲分布、热带亚洲至热带非洲分布及热带亚洲分布合计)占各地方植物区系的0.84%到94.38%,其最低值出现在中国西北部的新疆和青海地区,最高值出现在中国云南南部和海南;(3)热带分布属在<北纬30°的地区占优势,除热带亚洲至热带美洲间断分布外,其它热带成分随纬度增加迅速减少;(4)温带分布属(北温带分布、东亚和北美间断分布、旧世界温带分布、温带亚洲分布、地中海区、西亚到中亚分布、中亚分布和东亚分布合计)占各地方植物区系的5.1%至98.83%,其最高值出现在中国西北部的新疆地区,最低值出现在中国云南南部和海南;(5)除东亚和北美间断分布、东亚分布和中国特有分布外,其它温带成分随纬度增加迅速增加;(6)在温带成分中,东亚和北美间断分布及东亚分布属主要出现在中国亚热带到暖温带地区,北温带分布、旧世界温带分布和温带亚洲分布属在中国北部占优势,而地中海区、西亚到中亚分布和中亚分布属则在中国西北部占优势;(7)除世界分布、东亚和北美间断分布、东亚分布和中国特有分布外,所有其他成分都显示了与气候因素密切相关,其中,北温带分布属与年均温和年降雨量最为密切相关。
