Researchers identify a new trigger of cellular self-destruction

Posted on March 17, 2015 by

Researchers have identified a bacterial protein that triggers a self-inflicted cell death pathway in immune system cells and could lead to a better understanding of an important cellular structure. The protein initiates a cascade of events that leads the lysosome, a cellular structure filled with enzymes that break down and digest cellular material, to open […]

Song complexity determines high frequency hearing in birds

Posted on March 16, 2015 by

  Several factors appear to have affected the evolution of bird song. In particular, birds that live in wooded habitats seem to use relatively low-frequency, tonal songs that are not overly degraded by reverberations off of trees and leaves. In contrast, birds that live in open habitats tend to use quite complex songs with rapid […]

Finding mooonlighting proteins from genomes

Posted on February 17, 2015 by

Moonlighting proteins, proteins which have two or more independent functions, have drawn an increasing attention as more and more such examples have been discovered in recent years. However, the number of known moonlighting proteins is still not large enough to elucidate the overall landscape of their functional diversity. In this work, published on Biology Direct, […]

Thinking ahead: how a unicellular nitrogen fixing cyanobacterium manages its gene expression to accommodate the challenges it faces through out a 24-hour day

Posted on February 12, 2015 by

    Cyanobacteria are important model organisms that use sunlight to power photosynthesis and some even fix N2 from the atmosphere to make proteins and DNA. In addition, cyanobacteria are the only prokaryotes known to have a circadian clock that helps regulate gene expression throughout the day-night cycle. One of our objectives is to understand […]

Surprises for Agrobacterium T-DNA integration into host genomes

Posted on February 10, 2015 by

Agrobacterium species transfer DNA (T-DNA) to host plants, a unique example of interkingdom horizontal gene transfer. Once inside the nucleus, T-DNA integrates into the host genome. The mechanism of integration has been widely debated, but the current favored hypothesis is that double-strand T-DNA molecules link to double-strand DNA break sites in plant chromosomes using the […]
