Gene Expression: Sizing It All Up
Genomic architecture appears to be a largely unexplored component of gene expression. That architecture can be related to chromatin domains, transposable element neighborhoods, epigenetic modifications of the genome, and more. Although surely not the end of the story, we are learning that when it comes to gene expression, size is also important. We have been surprised to find that certain patte...
متن کاملSizing Up Repo ∗
We measure the repo funding extended by money market funds (MMF) and securities lenders to the shadow banking system, including quantities, haircuts, and repo rates by type of underlying collateral. We find that repo played only a small role in funding private sector assets prior to the crisis, as most repos are backed by Treasury and Agency collateral. Repo with private sector collateral contr...
متن کاملSizing up Septoria
UNLABELLED Septoria represents a genus of plant pathogenic fungi with a wide geographic distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. A major aim of this study was to resolve the phylogenetic generic limits of Septoria, Stagonospora, and other related genera such as Sphaerulina, Phaeosphaeria and Phaeoseptoria using sequences of the the part...
متن کاملSizing up dogs
Why are dogs of interest to human geneticists? Dog breeds display an extraordinary amount of variation in skeletal structure, including overall size, leg length and width, and variants of skull shape. Breeds thus present geneticists with great opportunities for studying the genetics underlying common traits that have become fixed as part of various breed standards. Many traits were selected bec...
متن کاملSizing up microbes
The size range of life forms is dictated by basic principles of physics. Large microorganisms, with sizes approaching a millimeter, have compensating features that address the immutable laws of physics. For pathogens, size may impact a range of functions, such as adherence and immune evasion. We review several recent studies on factors impacting, and impacted by, the size of microorganisms.
