ABSTRACT.
Solanum commersonii is a wild species related to the cultivated potato. Some S. commersonii genotypes have been proven to be resistant to the pathogenic bacteria Ralstonia solanacearum, which causes damage in potato and other economically important crops. Here an expression analysis of the response of a resistant S. commersonii genotype against R. solanacearum was performed using microarrays. The aims of this work were to elucidate the molecular processes involved in the interaction, establish the timing of the response, and contribute to identify genes related to the resistance. The response to the treatment was already initiated at 6 h post-inoculation (hpi) and was established at 24 hpi; during this period, a high number of genes was differentially expressed and several candidate genes for the resistance of S. commersonii to R. solanacearum were identified. At an early stage, the photosynthetic process was highly repressed and several genes encoding proteins related to reactive oxygen species (ROS) production were differentially expressed. The induction of ERF and ACC-oxidase genes related to the ethylene pathway and PR1 related to the salicylic acid pathway suggested the induction of both pathways, and back up the previously reported hemibiotrophic nature of the pathogen. Five genes related to plant defence and observed to be differentially expressed at the first two time points were validated by real time PCR. This work gives a glimpse to the molecular processes involved in S. commersonii resistance and identifies the species as a valuable genetic source for potato breeding against bacterial wilt.

The application of biotechn'ology to crop improvement has been the focus of much research around the world. Tissue culture and selection of somaclonal variation were developed many years ago, followed more recently by molecular markers and genetic engineering. This meeting focused on providing updates on the actual successes to date on the application of several areas of biotechnology to wheat improvement. What is clear is that there continues to be optimism regarding the potential for biotechnology to be applied to wheat improvement. It is also noteworthy that as was predicted by many scientists, many approaches are proving more difficult in wheat than in other crops. Molecular markers, for example, are difficult to apply routinely given the large genome, hexaploid genetics, and lower levels of polymorphisms. New marker systems such as AFLPs and microsatellites are an improvement over previous RFLPs, but still require significant investments to achieve similar results possible in other, more amenable species. What is encouraging are the successes to identify the genetics of complex traits in wheat such as quality, Fusarium and rust resistance. Some of these will surely provide useful applications in wheat improvement and all mapping efforts provide critical genetic information for further studies at the gene level. These will be increasingly important as genomic approaches (gene expression, proteomics, etc.) become available and are applied to wheat. In many ways, these latest genomics approaches should be more 'genome independent' and thus readily applicable to large, complex genome species such as wheat. Coupled with the relatively easy ability to produce doubled haploids, wheat may prove to be an extremely important species for genomic studies.
