Investigating Host Plant Resistance to Aphid Feeding through SAS® Text Miner

The processes of host plant resistance to insect feeding and pathogen attack involve several complicated plant defense pathways comprising numerous regulations of pathogen-related gene expressions. The aim of this study is to examine the ethylene signaling defense pathway of melon plants. We present a novel way of applying text mining in plant resistance research literature reviews. SAS ® Text Miner is employed to analyze current literature emphasis with the purpose of identifying interesting and important research trends in the field of host plant resistance to insect attacks. We show that ethylene, jasmonic acid, salicylic acid, and calcium signaling pathways are major emphases in the plant-pathogen interaction field. Additionally, SAS ® Enterprise Guide ® is used to analyze gene expression changes in ethylene signaling pathway.
