Our new 2013 review of plant defense responses and resource re-allocation published in Frontiers in Plant Science and online HERE.  Read about the uncommon wisdom of early poets and natural historians, who had a pretty good idea of how plants should allocation precious resources to maximize their fitness.  For example “The budget of nature is fixed; but she is free to dispose of particular sums by an appropriation that may please her. In order to spend on one side, she is forced to economize on the other side”  (in Darwin 1872)
