The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

In the prediction of protein structural classes, the residue order along the sequences takes an important role; while as in the prediction of protein subcellular locations, the amino acid composition is the most important factor.

在蛋白质的亚细胞定位预测中，氨基酸组成仍然是最重要的特征，蛋白质的亚细胞位置与序列同源性的关系没有结构与序列同源性的关系强。

Methods Mimicry and speculation on possible displaced amino acids in proper positions of peptide increased the biological effects of TNFR blocking peptide by compote modeling. The original peptide and its mutant were synthesized. The competitively inhibitory effects on green fluorescence protein-tumor necrosis factor fusion protein with TNFR were compared between original peptide and its mutant (receptor competitively inhibitory binding assays). The inhibitory effects on cytotoxicity were compared between original peptide and its mutant.

Soybean meal appears to be the preferred protein meal to fill the EU's needs as consumption of other protein meals has steadily declined since 2000-01 with the largest declines noted for sunflowerseed and copra meal.

豆粕似乎更能满足欧盟对蛋白粕的需要，因为其它蛋白粕的消费量自2000－2001年度以来持续下降，其中降幅最大的是葵花籽粕和椰子仁粕。

The leaf Bt protein in whole growth period showed in shape of "V", and the boll shell had higher Bt protein, it was benefit to resistant to boll worm in cotton.

在碳氮代谢生理方面表现为盛铃后碳氮代谢增强；Bt蛋白变化呈V型，但铃壳中含量高，有利于增强对棉铃虫的抵抗。

Cottonseed meal is a floristic protein resource, which nutrient value is even better than other cereal protein.
