Mechanisms of sugarcane response to herbivory

Deciphering plant-insect interactions at the molecular level is one of the major topics of interest in contemporary plant biology research. In the last few years, various aspects of the plant response to insect damage have been investigated, including the characterization of direct and indirect responses, the regulation of gene expression resulting from insect attack and the signal transduction pathways. Such research has resulted in the proposal of new methods to enhance host resistance to insect pests, including the use of insecticidal genes that can be transferred by genetic engineering into target crops. By integrating the understanding of how plants react to insect damage with the techniques of molecular biology researchers should be able to increase the wide range of methods available for the control of insect pests. The sugarcane transcriptome project (SUCEST) has allowed the identification of several orthologues genes involved in the plant response to insect damage. In this paper we summarize several aspects of the complex interaction between plants and insects and describe the use of in silico analysis to provide information about gene expression in different sugarcane tissues in response to insect
