A Bacillus subtilis strain W2-24 has been approved officially for bio-fungicide agent controlling wheat diseases.A new and suitable formulation are in development.The fermentation broth of the W2-24 was extracted with three organic solvents (Hexane, Ethyl acetate, n-Butyl ethanol) to find an efficient method enriching the active components antagonistic to wheat take-all pathogen Gaeumannomyces graminis var.tritici..The result revealed that the ethyl acetate extract possessed the strongest activities.The ethyl acetate extract was identified as the main components of the observed antagonistic activity.These extracts were further purified with TLC and HPLC.The result showed that these active components have high similarity in polarity.Further purification and analysis are in progress with other techniques.

光强是影响植物光合作用的重要环境因子之一。前人已经对植物光合作用适应强光的机制进行了大量研究,但以往研究主要关注了植物对不同强光的适应,而忽视了强光照光时间的可能影响。实际上,光胁迫至少包括光强和光照时间两个方面,我们推测强光胁迫下照光时间很可能也会明显影响光合作用的适应策略和机制。因此,我们针对这种情况以玉米为材料进行了研究,试图阐述强光不同照光时间对玉米光合作用适应的规律和机制的影响。本实验以
