英文摘要	To achieve a high yield of tropane alkaloids (TA) and exploit the alpine plant sustainably, an optimized protocol for induction and establishment of hairy roots culture of Prezwalskia tangutica Maxim was developed through selection of appropriate Agrobacterium strain and the explant type. The hypocotyl is more readily facile to induce the HR than the cotyledon is when infected with the three different agrobacterium strains. MUS440 has an efficiency (of up to 20%), whereas the ATCC10060 (A4) can induce HR on both types of explants with the highest frequency (33.33%), root length (21.17 +/- 2.84 cm), and root number (10.83 +/- 1.43) per explant than the other strains. The highest HR production resulted from using hypocotyl as explants. Independent transformed HR was able to grow vigorously and to propagate on a no-hormone 1/2MS liquid medium. The presence of pRi rolB gene in transformation of HR was confirmed by PCR amplification. In the liquid medium, the HR growth curve appeared to be "S" shaped, and ADB had increased to 4.633 g/l. Moreover, HPLC analysis showed that HR lines have an extraordinary ability to produce atropine (229.88 mg/100 g), anisodine (4.09 mg/100 g), anisodamine (12.85 mg/100 g), and scopolamine (10.69 mg/100 g), which were all more significant than the control roots. In conclusion, our study optimized the culture condition and established a feasible genetics reactor for P. tangutica green exploration and biological study in the alpine region.
