We explored the contribution of the cyanide-resistant respiration to increasing chilling tolerance and decreasing chloroplast damage in rice seedlings,the function of cyanide-resistant respiration during the greening of etiolated rice seedlings and effects of exogenous H_2O_2 on chilling-resistance of rice seedlings.

A Preliminary Discussion on Green Transformation of Resource-based Cities:Enlightenment from the Practice of Taiyuan

This paper introduces the green transformation,analyzes the relationship between the rural and urban construction plan and the green transformation,and advances the importance of taking the lead in promoting the green transformation for the rural and urban construction plan.

The scientific concept of development requires the resource-based cities to explore a new way of sustainable development and to realize green transformation.

Some molecular strategies for controlling transgene escape were summarized, which included chloroplast transformation, male sterility, terminator technology, incompatible genomes, GM "gene deletor" The advantage and problem of these strategies were analysed, and then some constructive countermeasures and proposal to preventing transgene escape in the future were put forward.

In order to eliminate the maintain-line seeds from the cytoplasm male sterile line seeds a selectable marker gene was inserted into the cytoplasmic genome of the male sterile line through chloroplast transformation.

The text has surveyed Crop genetic engineering from several respects such as resistance to herbicide, disease beet resistance,drought tolerance, and that it has been reviewed the progress of directly making use of genetic engineering to improve the quality and yield of the crop, and the new advance in chloroplast transformation was introduced.
