“Our analysis of the pea aphid genome opens the door for researchers to better understand the biology of the aphid at the genetic and molecular levels,” said Marina Caillaud, associate professor of biology at Ithaca College.
“Because the pea aphid is a close relative of other insects that are serious agricultural pests worldwide, understanding the genetic underpinnings of this animal’s complex ecology—including its capacity to parasitize agricultural crops—will help design new strategies to disrupt pathways and control pests.”
Working with Caillaud in her laboratory were two undergraduates, Eric van Fleet and Jason Diaz. Both graduated in 2009 with bachelor’s degrees in biochemistry. Also playing important roles in the research were scientists from two other area institutions, the Boyce Thompson Institute for Plant Research and Cornell University. The Ithaca-area scientists led the effort to annotate genes involved in metabolizing and transporting sugars, amino acids, purines (the building blocks of DNA and RNA) and other metabolites.
Members of the three laboratories also contributed to identifying pea aphid genes important in overcoming plant defenses, including enzymes in aphid saliva and genes that play a crucial role in aphid transmission of viruses as they feed on plants.
The genome was sequenced at the Baylor College of Medicine’s Human Genome Sequencing Center and published in the Feb. 23 issue of “Public Library of Science—Biology” (PLoS Biology). The research was supported by the Ithaca College Department of Biology, the U.S. Department of Agriculture, the National Institutes of Health, and the National Science Foundation.The “PLoS Biology” article is available at: http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1000313.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
