RNA silencing plays a critical role in plant defense against viral infection. Plants use virusderived
small interfering RNA to target and silence invading viruses. The antiviral silencing
pathway can be broken down into three conceptual stages: initiation, amplification, and systemic
movement. The molecular mechanisms of silencing initiation are not well...
In eukaryotes, ARGONAUTE proteins (AGOs) associate with microRNAs (miRNAs), short
interfering RNAs (siRNAs), and other classes of small RNAs to regulate target RNA or target
loci. Viral infection in plants induces a potent and highly specific antiviral RNA silencing
response characterized by the formation of virus-derived siRNAs. Arabidopsis thaliana has...

The discovery of new antibiotics reached its peak during the golden era of antibiotics in the mid 20th century and continued to thrive until the 1980s. However, after more than 50 years of fruitful exploration and exploitation of microbial natural products the discovery rate of new antibiotics has dropped drastically...
In the US Pacific Northwest, rockfishes Sebastes spp. have recently become a focus for increased management efforts; several species are currently managed under extreme conservation measures due to low population levels and intense fishing pressure. Rockfish recruitment is extremely variable, and a better understanding of the factors influencing recruitment and...
Tungsten alloys containing approximately 0.75 and 2.3 vol pct Zr0₂
were prepared by powder metallurgical methods from blends
of commercial
tungsten powder and ZrW₂ powder.
A heat treatment of the extruded rods
at 1800°C was found to produce a stable structure with a
dispersion of
Zr0₂ particles in the tungsten...
