Dielectric spectroscopy of Tobacco Mosaic Virus [PDF]

Biochimica et Biophysica Acta (BBA) - General Subjects, 2003
The dielectric properties of the Tobacco Mosaic Virus (TMV) have been measured using time domain dielectric spectroscopy (TDDS) in the temperature range from 1 to 40 degrees C. A single dielectric dispersion is observed in the MHz range. The activation energy of the process is found to be in the range 1-2 kcal/mol.

Mineral oil interferes with potato virus Y in aphid stylets

Plant Pathology, Volume 72, Issue 1, Page 170-178, January 2023., 2023
The mineral oil and the virus were visualized inside the insect's stylets and the mechanism by which the oil impacts virus acquisition seems to take place in the very early stages of acquisition. Abstract Mineral oils have been used for many decades to control the transmission of plant viruses and their ensuing epidemics.

Determining the Relationship Between Salicylic Acid Levels and Systemic Acquired Resistance Induction in Tobacco

Molecular Plant-Microbe Interactions, 1998
Salicylic acid (SA) has been proposed as the systemic signal for the induction of systemic acquired resistance (SAR). It has been suggested that SA is synthesized at the site of pathogen-induced necrosis and is translocated to induce SAR in uninfected ...

Robust self-assembly of nonconvex shapes in 2D [PDF]

arXiv, 2023
We present fast simulation methods for the self-assembly of complex shapes in two dimensions. The shapes are modeled via a general boundary curve and interact via a standard volume term promoting overlap and an interpenetration penalty. To efficiently realize the Gibbs measure on the space of possible configurations we employ the hybrid Monte Carlo ...

High‐fidelity in vitro packaging of diverse synthetic cargo into encapsulin protein cages

Angewandte Chemie International Edition, Accepted Article.
Cargo‐filled protein cages are powerful tools in biotechnology with demonstrated potential as catalytic nanoreactors and vehicles for targeted drug delivery. While endogenous biomolecules can be packaged into protein cages during their expression and self‐assembly inside cells, synthetic cargo molecules are typically incompatible with live cells and ...
