A survey of China's plant biotechnologists shows that China is developing the largest plant biotechnology capacity outside of North America. The list of genetically modified plant technologies in trials, including rice, wheat, potatoes, and peanuts, is impressive and differs from those being worked on in other countries. Poor farmers in China are cultivating more area of genetically modified plants than are small farmers in any other developing country. A survey of agricultural producers in China demonstrates that Bacillus thuringiensis cotton adoption increases production efficiency and improves farmer health.

Five are too many: It is known experimentally that [(Cp′)2Zr(N2)Zr(Cp′)2] (Cp′=C5H5−nMen) with n=4 activates N2 for hydrogenation, but the complex with n=5 does not. This difference in reactivity arises from the N2 coordination mode (see scheme): For n=0–4, N2 is side‐on coordinated—the most suitable mode for hydrogenation—whereas for n=5, N2 is end‐on coordinated owing to steric repulsion between five Me groups.
