Specific recognition and degradation of stylar S-RNase for self-pollen tube RNA, resulted in the stop of self-tube growth in Prunus mume. The recognition specificity of stylar S-RNase for the RNA weakened with the rise of temperature, consequently regulating the self-incompatibility reaction in Prunus mume.

果梅花柱S-RNase特异性识别并降解自花花粉管RNA，导致自花花粉管停止生长；随着温度的升高花柱S-RNase对花粉管RNA的识别特异性减弱，从而调节果梅的自交不亲和性反应。

In this study, nonionic surfactant sorbitan trioleate (Span 85) was modified with Cibacron Blue F-3GA to become an affinity surfactant (CB-Span 85) and to form affinity-based reversed micelles while dissolved in hexane. Since the CB molecule possesses a specific conformation that mimics nicotinamide adenine dinucleotide, it can bind strongly and specifically to a wide range of nucleotide-dependent enzymes such as dehydrogenases and kinases. Moreover, high protein transfer efficiency in the reverse micelles can be easily achieved by controlling the ionic strength of the aqueous phase.

本实验使用非离子型界面活性剂Span 85与蓝色染料分子Cibacron Blue F-3GA结合，形成具有亲和性的界面活性剂 CB-Span 85，由於CB染料分子具有与NAD+相似的结构，可与含核苷酸部位的蛋白质具有亲和力，将CB-Span 85溶於有机溶剂形成反微胞相，可有效的提高反微胞的选择率，可以只控制离子强度来调节蛋白质进出反微胞的效率。

And 0.949〓 respectively. From the model, the substitution of Pro (119)αto Ala in bar-headed goose Hbα〓β〓 interface, which is unique among bird and mammal Hbs and thought to be critical for the enhanced oxygen affinity in bar-headed goose Hb, causes no significant change in protein structure.

大量的研究工作认为，鸟类和哺乳动物Hb分子中a〓β〓亚基交界面唯一的氨基酸突变：Pro（119）α→Ala对于斑头雁Hb分子O〓亲和性的提高是关键的。

Crystal structures of bar-headed goose aquomet hemoglobin and greylag goose oxy Hb were determined and compared, which confirms the previous postulation that α119 mutation leads to the higher oxygen affinity of bar-headed goose Hb, but indicates that β125 mutation might also make part contribution.

通过对斑头雁水合高铁血红蛋白和灰雁氧合血红蛋白的晶体结构研究，证实了前人关于α119突变导致斑头雁血红蛋白的氧亲和性提高的假说，同时推测β125突变可能也有部分贡献。
