Strengthening coffee

12.07.2005


Is your cup of coffee suffering from fertility problems? If you’re drinking the instant variety it may very well be! The Robusta crop (Coffea canephora), which is the main variety for producing instant coffee, suffers from ’self-incompatibility’ so can’t pollinate itself. This presents a dilemma for coffee farmers who have to grow it in mixed plantings so that cross-pollination takes place – but which varieties to cross with which?



Sylvester Tumusiime (University of Nottingham, UK) will be presenting his work on coffee breeding on Monday 11th July at the Society for Experimental Biology Annual Main Meeting in Barcelona [session P4/E4.26] which shows that this problem might be overcome by developing molecular markers which can identify self-incompatibility genotypes to improve breeding strategies. In collaboration with the Ugandan Kawanda Agricultural Research Institute (KARI), Tumusiime and colleagues have investigated the possible involvement of a group of proteins called ribonucleases (RNA-degrading enzymes) in the self-incompatibility (S) mechanism. Several distinct ribonuclease patterns have been identified in female reproductive tissues. As plants with the same S-genotype cannot fertilise each other, research is focussed on identifying different S-genotypes which will help farmers to choose the best mixture of varieties to grow and will also facilitate future cross-breeding.

Unlike Robusta, mainly used for instant coffee, the higher value Arabica crop, favoured for filter coffee, is self-compatible and therefore easier to cultivate and maintain as breeding material. However, the high genetic diversity of Robusta offers the potential of increasing the resistance to diseases and environmental changes, improving the quality of our future brew.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
