Abstract:"Plant responses to herbivores are complex. 108 cDNA clones representing genes relating to plant responses to chewing insect-feeding, pathogen infection, wounding and other stresses were collected. Northern blot and cDNA array analysis were employed to investigate gene expression regulated by piercing-sucking insect, brown planthopper (BPH), Nilaparvata lugens (Homoptera: Dephacidae) on both the resistant and susceptible rice genotypes. After BPH feeding in rice for 72 h, the expression of most tested genes was affected. 14 genes in resistant rice variety B5 and 44 genes in susceptible MH63 were significantly up- or down-regulated. Most of the well-regulated genes were grouped in the categories of signaling pathways, oxidative stress/apoptosis, wound-response, drought-inducible and pathogen-related proteins. Those related to the flavonoid pathway, aromatic metabolidsm and the octadecanoid pathway were mostly kept unchanged or down-regulated. Our results indicate that BPH feeding induces plant responses which would take part in a jasmonic acid-independent pathway and crosstalk with those related to abiotic stress, pathogen invasion and phytohormone signaling pathways"
