From the perspective of the characteristics of genetically modified crops, there are mainly herbicide-resistant, insect-resistant and disease-resistant varieties. In the past five years, the planting area of ​​herbicide-tolerant (Roundup) genetically modified crops has been dominant, and insect-resistant transgenic crops have been second. In 2000, soybeans, corn, cotton, etc., which were used for herbicides (Roundup) accounted for 74% of the total 44.2 million hectares, and 8.3 million hectares were planted with Bt corn, which was equivalent to 19%; both were resistant to herbicides. Roundup), a pest-resistant genetically modified crop, accounts for 7%. It is worth noting that the number of herbicide-tolerant (Roundup) transgenic crops increased from 2 810 in 1999 to 32.7 million hectares in 2000, while crops carrying both herbicide-resistant genes and insect-resistant genes increased from 290 in 1999. By 3.2 million hectares in 2000, however, insect-resistant GM crops fell from 890 in 1999 to 8.2 million hectares in 2000. Crops with several transgenic traits can gain more market share, which is the trend of future development of GM crops.
PMU is used to produce estrogen and hormone-replacement drugs such as Premarin, PremPro and PremPhase and DUAVEE, a "PremPro-Lite" which contains Premarin. PMU drugs are made by keeping mares constantly pregnant and collecting their estrogen-rich urine. The horses should be in good healthy, age from 4-15 years old, the color should be dark. the horses should be check-up and disinfected during the transportation. The blood taking should be called off immediately when infectious disease is found, any medicine of Penicillin and streptomycin is forbidden to use.
