Maize (<jats:italic>Zea mays<\/jats:italic>) seedlings were subjected to infestation for approximately 2 weeks by the root herbivore southern corn rootworm (SCR) <jats:italic>Diabrotica undecimpunctata howardi<\/jats:italic>, and changes in transcript abundance within both roots and shoots were analyzed using a 57K element microarray. A total of 541 genes showed statistically significant changes in transcript abundance in infested roots, including genes encoding many pathogenesis\u2010related proteins such as chitinases, proteinase inhibitors, peroxidases and <jats:italic>\u03b2<\/jats:italic>\u20101,3\u2010glucanases. Several WRKY transcription factors \u2013 often associated with biotic responses \u2013 exhibited increased transcript abundance upon SCR feeding. Differentially expressed (DE) genes were also detected in shoots of infested vs control plants. Quantitative Reverse Transcriptase Polymerase Chain Reaction (RT\u2010PCR) was used to confirm patterns of transcript abundance for several significant DE genes using an independent experiment with a 2\u20136 day period of SCR infestation. Because of the well\u2010documented roles that jasmonic acid (JA) or salicylic acid (SA) play in herbivory responses, the effect of exogenous JA or SA application on transcript abundance corresponding to the same subset of SCR\u2010responsive genes was assessed. The response of these genes at the level of transcript abundance to SA and JA differed between roots and shoots and also differed among the genes that were examined. These data suggested that SA\u2010 and JA\u2010dependent and independent signals contributed to the transcriptome\u2010level changes in maize roots and shoots in response to SCR infestation.<\/jats:p>","DOI":"10.1111\/j.1399-3054.2011.01557.x","type":"journal-article","created":{"date-parts":[[2011,12,15]],"date-time":"2011-12-15T14:55:23Z","timestamp":1323960923000},"page":"303-319","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Root herbivory: molecular analysis of the maize transcriptome upon infestation by Southern corn rootworm, <i>Diabrotica undecimpunctata howardi<\/i>"],"prefix":"10.1111","volume":"144","author":[{"given":"Susan D.","family":"Lawrence","sequence":"first","affiliation":[]},{"given":"Nicole G.","family":"Novak","sequence":"additional","affiliation":[]},{"given":"Walid El","family":"Kayal","sequence":"additional","affiliation":[]},{"given":"Chelsea J.\u2010T.","family":"Ju","sequence":"additional","affiliation":[]},{"given":"Janice E.
