Am 17. April 2014 gab es wieder einen Vortrag zu einem World Community Grid Projekt. Endlich ist auch die Wiederholung online verfügbar.
Dr. Hung explained that rice presents a unique challenge to plant scientists. It is the most important single food crop, providing about one-fifth of all the calories consumed by humans. Past plant breeding efforts have produced strains of rice with higher yields and better nutritional content, and it is vital to keep improving this important food resource as the world’s population grows and its climate changes. However, it is slow and difficult work to improve rice further, because most of the basic building blocks of the plant – its proteins – are a mystery. The rice genome encodes about 50,000 proteins, but the structures of these proteins are mostly unknown, so scientists do not know what role each protein plays in the plant. If these roles were known, plant breeding efforts could be better focused and potentially much more successful.
Nutritious Rice for the World used modeling techniques to predict these protein structures based on the genomes of two strains of rice. Volunteers simulated about 100 trillion possible structures, from which the researchers selected the 300,000 best. This represents about 5 possible structures for each gene or set of genes that they studied. The structures are now publicly available for download from two websites maintained by the research team. Now that these structures are available, researchers can compare them to the known structures of other proteins from other organisms and get a better idea of the specific role that each protein plays in the rice plant.
In addition to the huge database of calculated protein structures, the project also improved the computational methods used to simulate the proteins themselves. These improved methods mean that future protein research will be able to deliver much more efficient and accurate results.
Auch Sie können zur Arbeit des World Community Grids beitragen und Ihre ungenutze Rechnerkapazität weitergeben um humanitäre Projekte zu unterstützen. Häufig ist der Computer nicht ausgelastet, wenn wir ihn benutzen. Die Bearbeitung eines Word-Dokuments beansprucht nur einen geringen Teil der eigentlichen Leistung. In dieser Zeit kann das WCG im Hintergrund für ein humanitäres Projekt rechnen, ohne dass Sie überhaupt etwas davon mitbekommen.
