Korea-Germany Joint Symposium on Plant Biotechnology

I am pleasure to share the experience that I had in last two days in symposium.

The research data presented by German scientists and Korean Scientist was really different.

Main differences in the research areas of two countries can be stated as follows:

1. Germans have considered very big pictures and goals with expected application oriented results. On the other hand very few Korean researchers could give such kind of data.

2. The strong point of Korean research is that they focus on small points and make a good story to be published in high impact factor journals.

3. As compare to Korea, Germans have more high throughput techniques and they have many collaborations across globe to carry out specialized tasks.

4. Germans are very strong in Genomics and utilizing sequencing technologies while Koreans are very sharp to extract available data form database for their research.

Some of the talks that impressed me are summarize below:

1. Seasonal flowering in annual and perennial plants. By George Coupland (MPIZ)

2. Towards a blueprint for C4 photosynthesis derived from comparative transcriptomics of closely related C3 and C4 species. By Andreas Weber (University of Dusseldorf)

3. Molecular, biochemical and cellular studies of E3 ubiquitin ligases in response to drought stress in Arabidopsis. By Woo Teak  Kim (YONSEI University)

4. Barley- at the transition to genomics based crop improvement? By Nils Stein (IPK Gaterslenben)

5. Iron fortification of rice seeds through activation of Nicotinamine Synthase gene. By Gynheung An (Kyunghee University)

BIOCHEMISTRY: A Never-Ending Story

More than 50 years ago, Reichard and colleagues elucidated how cells make their DNA building blocks—the deoxyribonucleotides or dNTPs (1). They found that the enzyme ribonucleotide reductase (RNR) converts ribonucleotides (RNA building blocks) to corresponding dNTPs. One would expect that such a central pathway for all living cells would be meticulously mapped by now. Yes—and no. Researchers have described several classes and subclasses of RNRs (see the figure) that appear to have the same evolutionary origin (2–5), but involve different chemical cofactors, and so enable cells to construct dNTPs under different environmental conditions. Whenever the field seems settled, however, fascinating new aspects appear (1, 2). On page 1526 of this issue, Boal et al. (3) report crystal structures of RNR complexes from the bacterium Escherichia coli that, together with earlier studies, confirm and neatly illuminate yet another way cells can construct dNTPs, this time with the help of manganese (Mn).

Plant Biotechnology

Norman Borlaug himself is convinced that the world has the technology to permit a population of 10 billion people to be sustained but he is concerned that farmers may be prevented from exploiting the new technology by small, vociferous, well-financed groups  of anti-science zealots. These affluent campaigners can afford to pay high prices for poorly regulated 'organic' food production. On the other hand the billion chronically poor and hungry people already in the world cannot do so and the crisis seems likely to grow as the population increases.
