International Aphid Genomics Consortium publishes genome sequence of the pea aphid

24.02.2010
An international consortium of leading scientists from 15 countries, including researchers at RIKEN, has published the first ever complete genome of an aphid species, the pea aphid Acyrthosiphon pisum.

In a series of landmark papers to appear in journals including PLoS Biology and Insect Molecular Biology, the scientists shed light on the identity of an organism whose genome sequence offers solutions to central questions in basic biology and applied agriculture.

Both a highly destructive pest and highly complex organism, the aphid is known for the damage it causes to crops, feeding on the phloem sap in plants and spreading deadly viruses. Yet aphids have also evolved complex life cycles, alternating between sexual and asexual reproduction, producing offspring with multiple phenotypes and forming symbiotic relationships with inherited bacteria.

Many of these unusual features find their origins in the 35,000 newly-identified genes of the pea aphid genome, 37% of which, the researchers show, are unique to aphids. Among other discoveries, the researchers find a highly increased number of genes associated with reproduction, gene expression, signaling and virus transmission, and a strikingly reduced repertoire of immunity-related genes. At the evolutionary level, the discovery of a dozen functional genes of bacterial origin constitutes the first systematic evidence of horizontal gene transfer from bacteria to a eukaryotic host.

As the world’s most important agricultural pest and one of its most biologically distinctive species, the aphid is of central concern to industry and science alike. The first published aphid genome provides a basis for the development of safer, more effective pest control techniques, while also setting the stage to exploring the genetic basis of a range of complex biological phenomena.

Im Focus: Superconducting vortices quantize ordinary metal

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.

These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
