| 英文摘要 | Strategies are still employed to reduce insect damage in crop production, including conventional breeding with wild germplasm resources and transgenic technology with foreign genes' insertion. Cultivated and Bt-transgenic rice (Oryza sativa) and two ecotypes of wild rice (O. rufipogon) were treated by a 72 h feeding of brown plant hopper (Nilaparvata lugens). Under the feeding of N. lugens, compared with the cultivated rice (568 and 4), more differentially expressed genes (DEGs) and differentially accumulated proteins (DAPs) were identified in transgenic rice (2098 and 11) and two wild ecotypes (1990, 39 and 1932, 25, respectively). The iTRAQ analysis showed 79 DAPs and confirmed the results of RNA-seq, which showed the least GO terms and KEGG pathways responding to herbivory in the cultivated rice. DAPs significantly enriched two GO terms that are related with Bph14 and Bph33 genes in rice. Most of DEGs and DAPs were related to plant biological processes of plant-pathogen interaction and plant hormone signal transduction, and hormone signaling and transcription factors regulate the immune response of rice to BPH. Our results demonstrated the similarity in the wild rice and Bt-transgenic rice for their transcriptomic and proteomic response to herbivory, while cultivated rice lacked enough pathways in response to herbivory. Statement of significance of the study: The iTRAQ analysis and RNA-seq were employed 39 to identify differentially expressed genes (DEGs) and differentially accumulated proteins (DAPs) in seedlings of cultivated, Bt-transgenic and two wild rice ecotypes under feeding of brown plant hopper. Wild rice showed DEGs and DAPs related to biochemical pathways of plant pathogen interactions and plant hormone signal transductions, while cultivated rice lacked enough pathways in response to herbivory. Crop domestication weakened the response of plants to herbivory, while the insertion of Bt gene might promote the response of plants to herbivory. Growing environment plays an important role in regulating gene networks of plant response to herbivory. Our results highlighted the importance of conservation of crop wild species. Significance: Insect damage is one of main factors in reducing agricultural production, and technologies and methods were employed to control insect pests in agricultural systems. Transgenic technology is developed to produce insect-resistant crops, but receive concerns on biosafety risks. Alternatively, crop wild species are important genetic resource in crop breeding to produce trait-specific varieties. Here, we investigated the molecular mechanisms of plant response to herbivory in wild, Bt-transgenic and cultivated rice, and found crop domestication weakened the response of plants to herbivory. The insertion of foreign Bt gene may promote the expression of other genes. In addition, our results showed growing environment plays an important role in regulating gene networks of plant response to herbivory. These results highlight the importance of wild species conservation, with the strategy of in situ conservation. |
