Small interfering (si)RNAs isolated from Brassica juncea leaves infected by Turnip mosaic virus (TuMV) were characterized by cloning and sequencing. The TuMV siRNA population was dominated by 21 and 22-nt long species originated mainly from the same siRNA hotspots, indicating operational similarity between the plant Dicer-like (DCL) enzymes. Robust GC bias was observed for TuMV siRNAs versus th...
Turnip mosaic virus (TuMV) is a potyvirus that is transmitted by aphids and infects a wide range of plant species. We investigated the evolution of this pathogen by collecting 32 isolates of TuMV, mostly from Brassicaceae plants, in Australia and New Zealand. We performed a variety of sequence-based phylogenetic and population genetic analyses of the complete genomic sequences and of three non-...
It was largely because of our interest in the turnip yellow mosaic virus (Markham & Smith, K. M., 1949) that we began our study of nucleic acids. This virus contains about 37 % by weight of ribonucleic acid, which is an unusually high proportion. All the infected plants which we have examined contain, as well as the virus, another characteristic and related protein in an amount equivalent to 25...
The ability of gecko lizards to adhere to a vertical solid surface comes from their remarkable feet with aligned microscopic elastic hairs. By using carbon nanotube arrays that are dominated by a straight body segment but with curly entangled top, we have created gecko-foot-mimetic dry adhesives that show macroscopic adhesive forces of approximately 100 newtons per square centimeter, almost 10 ...
