Broccoli is one of western Europe`s most popular and widely consumed vegetables. However, its shelf life is restricted to about 5 days at room temperature, making distribution and storage of the product difficult. Recent research presented today at the Society for Experimental Biology conference in Swansea could help us understand the genetics of this situation and may even lead to `supervarieties` of broccoli.
The popularity of broccoli is on the increase and it is used increasingly in value added products such as frozen foods and ready meals. In the UK, broccoli available in the summer is produced domestically. However, during the winter months the majority of the broccoli available in supermarkets has made the long journey from Spain - not an easy thing when the product itself has a shelf life of only 5 days.
Evy Mathas, a PhD student at Horticultural Research International, Wellesbourne, is attempting to understand this relatively rapid deterioration - research which may lead to improved commercial varieties. Senescence - the deterioration of the product - is characterised by a yellowing of the broccoli floret and a loss of water. In order to study this process, Ms Mathas carried out an extensive field trial in 2001, growing different varieties of broccoli and carrying out a detailed analysis on each post-harvest day. She has found a dramatic difference between these varieties. Some senesce in as little as 2 days, whilst others remain edible for 4 at room temperature. Her biochemical and molecular analysis has shown that this senescence is a result of a rather rapid loss of chlorophyll and a slight loss of protein from the floret.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
