Magnetic property of loess strata recorded by Kansu profile in Tianshan Mountains

Kansu (KS) profile is located in the east of Yili basin, western Xinjiang, where typical loess sediments are distributed. The magnetic parameters (such as IRM, SIRM SOFT, and M) and grain size in the KS profile were analyzed in the study. The results showed that the magnetic property of KS loess is dominated by ferrimagnetic minerals, such as magnetite and maghemite. Antiferromagnetic and superparamagnetic minerals also exist in the profile, but had less impact on magnetic susceptibility. Compared with the typical loess sediments of the central Loess Plateau in China, the strata of Kansu profile contained more magnetic minerals and hard magnetic minerals. The analysis of grain size for magnetic minerals indicated that the properties of loess and paleosol were respectively dominated by PSD/MD and coarse SSD magnetite. The research found that the contents of magnetic minerals in loess and paleosol sequences in Kansu profile were similar, but the proportion of fine grained magnetite and soft magnetic minerals were varying, which implies a positive relationship between the value of magnetic susceptibility and intensity of pedogenesis.

Cloning and Analysis of 5' Flanking Region of Sporamin A Gene from Sweet Potato

[Objective] The aim of the study is to clone the 5’ flanking region of Sporamin A gene from sweet potato. [Method] The sweet potato "Xushu 18" was used to amplify the 5’ flanking region of Sporamin A gene using specifically designed primers and then target fragment was analyzed by PLACE and PlantCare online. [Result] Besides the conserved elements including TATA-box and CAAT-box,the cis-acting elements including sucrose responsive element CMSRE1,SP8 acting site and some other regulatory sequence such as MYB binding site were also found in Spo A promoter sequence. The results suggest that the promoter has sucrose responsive function.[Conclusion] The study provided reference to reveal the regulation law of Spo A,and to develop high-level expression vectors promoted by Spo A promoter.     

Extraction of Triterpenoids with Antioxidant and Anti-tumor Activity from Agrocybe aegerita Mycelium and Spent Culture Medium

Different organic solvents (petroleum ether, ethyl acetate and ethanol) were used to extract A. aegerita mycelium and spent culture medium following growth of the fungus in submerged culture. All the extracts exhibited antioxidant and anti-tumor activity that may be linked to triterpenoids present in the extracts.
