A paper published today (26.11.02) in the December Issue of Journal of Applied Ecology by Cowgill et al describes the results of small-scale field trials that were used to assess the effect of PI-expressing potatoes on non-target soil organisms. The impact of a currently used PCN management option, the nematicide, aldicarb, on soil organisms was also studied.
The transgenic plants had an adverse effect on the fungal component of the soil microbial community, while the nematicide adversely affected the bacterial component of the microbial community. However, the changes brought about by the transgenic plants or nematicide use were small relative to natural fluctations in fungal and bacterial populations that were observed between sampling dates and growing seasons.
The observed changes in microbial community structure did not result in differences in soil function, as measured by C mineralization or rates of decomposition, between the treatments. There were also no differences in the abundance of soil microarthropds (mites and Collembola) or free-living nematodes between the treatments.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
