Application of RNA silencing to plant disease resistance [PDF]

open access: yes, 2012
To reduce the losses caused by plant pathogens, plant biologists have adopted numerous methods to engineer resistant plants. Among them, RNA silencing-based resistance has been a powerful tool that has been used to engineer resistant crops during the ...

Was Dan Janzen (1977) right about aphid clones being a "super-organism", i.e. a single "evolutionary individual"? : new insights from the use of molecular marker systems [PDF]

open access: yes, 2008
Dan Janzen proposed in a paper in 1977 (loc. cit.), that a clone of aphids and for that matter dandelions consists, respectively, of one large ‘super-organism’.
