The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.

雌核灭活是雄核发育的第一个关键步骤，为研究紫外线对斑马鱼卵的雌核灭活效果，将斑马鱼的卵采用干法或置于纯水、Ringer氏溶液和Cortland鱼用生理盐水进行紫外线照射，结果表明，各种方法中均得到畸形鱼苗，并经染色体检查大多为单倍体；四种方法中在Cortland鱼用生理盐水中灭活效果最好，120 mJ/cm2紫外线可以使雌核完全灭活；干法处理不能达到雌核完全灭活的目的，在纯水中灭活后的卵子受精率较低。

Using semi-quantitative RT-PCR, the differential expression profiles of eleven selected genes were confirmed in the ovaries of triploid and diploid. These genes fell in gene categories with a wide range of functions. The results indicated that triploidy affects the dynamic gene regulatory network in triploid ovary. This study established a firm basis for future investigation on characterization of crucial molecular events for normal ovarian development in shrimp.To further dissect exact gene functions for gonad development of shrimp, three differentially expressed genes between diploid and triploid ovary, PCNA (proliferating cell nuclear antigen), CAS/CSE1 (cellular apoptosis susceptibility protein/chromosome segregation 1) and SSRF (spermatogonial stem-cell renewal factor) were characterized on certain aspects.

利用抑制性消减杂交技术，建立了对虾二倍体和三倍体卵巢间的2个消减文库；在正向消减文库(以三倍体卵巢作为实验组，二倍体卵巢作为驱动组)中，鉴定到54个基因；在反向消减文库(以二倍体卵巢为实验组，三倍体卵巢为驱动组)中，鉴定到16个基因；选取11个差异表达的基因，利用半定量RT-PCR的方法对其在二倍体和三倍体卵巢间的表达进行了检测，均能很好地与消减结果相吻合；这些差异基因编码多种功能的蛋白，分析表明染色体的三倍化使三倍体卵巢中的基因调控网络受到了影响；为深入揭示维持卵巢正常发育的关键分子调控事件奠定了基础。

The research reveals that the scope of edaphic corrosion, which is the basic driving force for the heightening of stone pillars, is limited within about 10 m below ground surface, and the depth best for the development of stone forest is observed to be usually less than 1.5 m under the current natural conditions in the area.

研究表明，作为石林增长拔高源动力的土下溶蚀强度的影响范围是有限的，其下限约在土下10m处，而真正能促使石林快速发育的深度是在土下2m以内。

Arabidopsis response regulators,ARR4 and ARR5, were induced by the increased cytokinin contents at different time after seed germination. ARR4 responded to cytokinins at early time of seed germination, especially on the 6 d when seedlings were around true leaf initiation, while cytokinins induced ARR5 activation after 6 d of seed cultivation in light conditions, an obvious increase was on the 20 d when seedlings were around inflorescent shoot initiation.
