The biosynthesis of storage lipids (triacylglycerols) in higher plants is now known to occur via a number of different routes. These include the Kennedy pathway, using sequential acylation and acyl-CoA substrates. It has recently been observed that several other alternative pathways also operate, including acyl-CoA-independent enzymes, which appear to sequentially “enrich” storage lipids with polyunsaturated...

Until relatively recently, plant sphingolipids were generally considered to be minor cellular components of limited importance. However, research over the last decade has shown that sphingolipids play key roles in many aspects of plant biology, including reproduction, development and also biotic and abiotic stress. Sphingolipids play an important role as structural components of membranes and have...
Very long chain polyunsaturated fatty acids (VLC-PUFAs) are valuable commodities currently sourced either from vulnerable natural (marine) stocks or via expensive microbial fermentation. The advent of plant genetic engineering has raised the possibility of producing PUFAs in transgenic plants. This technology allows the transfer of a particular gene or trait into a non-native (heterologous) host,...
Synchrotron light sources can produce very intense beams of X-rays and ultra violet light for a range of applications, including protein crystallography, materials characterization and high resolution imaging. The Diamond Light Source is a 3rd generation synchrotron that has recently been constructed near Oxford, United Kingdom, which produces a 3 GeV electron beam in a ring of circumference of over...
This paper is about online, constant-time pose estimation for road vehicles. We exploit both the state of the art in vision based SLAM and the wide availability of overhead imagery of road networks. We show that by formulating the pose estimation problem in a relative sense, we can estimate the vehicle pose in real-time and bound its absolute error by using overhead image priors. We demonstrate our...
