DNA ejection from bacteriophage: towards a general behavior for osmotic suppression experiments M. Castelnovo∗ and A. Evilevitch† (Dated: December 18, 2007) We present in this work in vitro measurements of the force ejecting DNA from two distinct bacteriophages (T5 and λ) using the osmotic ejection suppression technique. Our datas are analyzed by revisiting the current theories of DNA packaging in spherical capsids. In particular we show that a simplified analytical model based on bending considerations only is able to account quantitatively for the experimental findings. Physical and biological consequences are discussed. I. INTRODUCTION Viruses have developped various specific strategies over the evolution in order to infect higher organisms.

The transfer of information-encoding genomes allows viruses to reprogram the cell fate of their hosts. Constituting 96% of all known bacterial viruses [A. Fokine and M. G. Rossmann, Molecular architecture of tailed double-stranded DNA phages, Bacteriophage 4, e28281 (2014)], the tailed bacteriophages deliver their DNA into host cells via an “ejection” process, leaving their protein shells outside of the bacteria; a similar scenario occurs for mammalian viruses like herpes, where the DNA genome is ejected into the nucleus of host cells, while the viral capsid remains bound outside to a nuclear-pore complex. In light of previous experimental measurements of in vivo bacteriophage λ ejection, we analyze here the physical processes that give rise to the observed dynamics.

  • From the President's Desk
    APRIL 2005 From the President’s desk: The sequence of the human genome underscores the necessity for genetic analysis to define gene function and validates the importance of genomic and genetic approaches in model organisms for gene discovery. The GSA promotes genetic research in model organisms and its application to human genetics via our journal Genetics, supporting public education and congressional lobbying through the Joint Steering Committee for Public Policy (www.jscpp.org) and in its sponsorship of scientific meetings. The GSA support of scientific meetings includes providing the crucial infrastructure, organization, administration, and financial foundation, as well as recognition for students and postdocs through the awards we sponsor. The society’s sponsorship of model organisms meetings in C. elegans, Drosophila, Fungi, Yeast and Zebrafish has enabled those research communities to hold conferences that are particularly accessible to students and postdocs who are our future. The support of the GSA has been key in enabling these very successful meetings while permitting each of the model organism communities the independence to organize the meeting according to their needs. In recognition of the importance of genomics in our field, this year the GSA will support a new meeting of biocurators and database developers with the goal of bringing together developers of these bioinformatics tools for a variety of organisms. Your membership in the GSA entitles you to a reduced registration fee for all of these meetings. The GSA will organize its own meeting “Genetic Analysis: Model Organisms to Human Biology,” Jan. 5-7, 2006 in San Diego to draw together the entire constituency of our society and to promote interactions with our colleagues directly studying human disease.

In particular, we outline the phenomenological hamiltonian approach developed recently (see Zandi, R., Reguera, D., Bruinsma, R., Gelbart, W.M. and Rudnick, J.

Sci., 101, 15556–15560) to account for the overwhelming prevalence of the Caspar-Klug “T- number” structures that are found for “spherical” viruses. We feature the role of “conformational switching energies” defining the competing multimeric states of the protein subunits. The results of Monte Carlo simulation of this model are argued to shed light as well on the mechanical properties and genome release mechanism for these viruses.

The "Self-assembly from atoms to life" workshop will bring together both young and senior scientists from around the world and it covers research areas that match UCLA physical chemistry professor Gelbart's broad range of interests that he has pursued over a 45- year career in research. It will take place October 3-5, 2016, at the Mesoamerican Centre for Theoretical Physics in Tuxtla Gutiérrez, Chiapas, Mexico. To facilitate travel to and from the event, the Marriott Tuxtla Gutiérrez Hotel has reserved a block a rooms at the special conference rate for October 2 through October 6. The workshop organizers are Profs. Alex Levine and Chuck Knobler from the UCLA Department of Chemistry and Biochemistry and Prof. Jaime Ruiz-Garcia, of the Physics Institute of the University of San Luis Potosi, in Mexico. One archetypal example of emergent phenomena in nature is found in the self-assembly of complex spatio-temporal structures, either in the relaxation of many-body systems toward their thermal equilibrium or in non-equilibrium steady states characterized by continuous energy throughput.

(Dated: July 2, 2019) Although the free energy of a genome packing into a virus is dominated by DNA-DNA interactions, ordering of the DNA inside the capsid is elasticity{driven, suggesting general solutions with DNA organized into spool-like domains. Using analytical calculations and computer simulations of a long elastic filament confined to a spherical container, we show that the ground state is not a single spool as assumed hitherto, but an ordering mosaic of multiple homogeneously-ordered domains. At low densities, we observe concentric spools, while at higher densities, other morphologies emerge, which resemble topological links. We discuss our results in the context of metallic wires, viral DNA, and flexible polymers. Introduction.

We developed a finite el- ement kinetic Monte Carlo simulation approach, which allows cross-links to reorganize in a three-dimensional network, to explore the dynamics of semiflexible networks with transient cross-links. We will first discuss this simulation strategy, and then apply this tool to explore the following aspects of semiflexible networks: The natural bundle formation and the dy- namics of bundle growth, especially in density and energy. The stress relaxation of networks with constrained filaments under affine strain field, and we find the linear shear elasticity of these networks mainly arises from the deformation change of the high-energy cross-links orientating in certain directions, and both the number and the elastic energy growth of these cross-links scales linearly with strain.

C. Research Interests A fundamental question in virology is how viruses package their genomes into stable virions. The major focus of research in my laboratory is to understand the replication and mechanism of genome packaging in RNA viruses of plants and insects with divided genomes. To this end, we are using Brome mosaic virus (BMV), a tripartite plant infecting RNA virus as a model system for analyzing various molecular interactions between coat protein and RNA leading to assembly of mature infectious virions. In addition, we are also applying molecular and proteomics approaches for dissecting the mechanism regulating the nuclear localization and replication of a satellite RNA of Cucumber mosaic virus and replication of Satellite tobacco mosaic virus (STMV). More recently, we initiated a projected to initiate the assembly of virus like particles of Human Immuno deficiency Virus (HIV) and Ebola Virus (EBV) in plants with an eventual aim of developing novel strategies of vaccine development.
