Metabolic Reconfiguration to Shift from a Growthto
a Defense-Oriented State
The numerous anatomical and chemical changes associated with induced resistance
require massive reprogramming of gene expression. For the quantitative analysis
of large-scale changes in gene expression, novel techniques have been developed
in recent years. Most notable among these approaches are microarray technologies
for the identification of differentially expressed transcripts, and even more
recently, techniques for high-throughput proteomic analysis (Kessler and Baldwin
2002; Kuhn and Schaller 2004; Giri et al. 2006; Lippert et al. 2007). With the
advent of these techniques, it is now possible to obtain a relatively unbiased account
of the plant’s response to herbivory. Many of the genes required for the expression
of known resistance traits were in fact shown to be upregulated during
