Scientists at the John Innes Centre (JIC), Norwich, UK, today report a breakthrough in understanding how plant cells control the direction of their growth. The report, in the international scientific journal Nature, describes a gene (called SCN1) which controls the activity of an enzyme that is critical to cell growth. The researchers have found that SCN1 keeps cell growth in check.
“This is an exciting discovery because the direction of cell growth is very important in determining the shape of plant cells and this controls the overall shape and structure of the plant”, says Professor Liam Dolan (project leader at JIC). “We already know about some of the processes involved in cell growth but this is a new insight into how they are localised so that cells can be made to grow in a particular direction”.
The researchers made their discovery from studies on root hair formation on roots of the model plant Thale Cress (Arabidopsis thaliana). Root hairs are important to the plant as they dramatically increase the surface area of the roots, providing a large surface through which water and minerals can be absorbed.

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,...
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...
