Abstract ：
DNA methylation participates in regulating the expression of coding and non-coding regions in plants. To investigate the association between DNA methylation and pathogen infection, we used whole-genome bisulfite sequencing to survey temporal DNA methylation changes in rice after infection with the rice blast fungus Magnaporthe oryzae. In contrast to previous findings in Arabidopsis, global DNA methylation levels in rice increased slightly after rice blast infection. We identified over 38,000 differentially methylated regions (DMRs), and hypermethylated DMRs far outnumbered hypomethylated DMRs. Most DMRs were located in transposable element regions. Using transcriptome analysis, we identified 8830 differentially expressed genes (DEGs) after 1, 3, and 5 days of infection. Over one-third of DEGs, most of which were CHH-type DMRs, were associated with DMRs. Functional analysis of the CHH DMR-DEGs indicated their involvement in many important biological processes, including cell communication and response to external stimulus. The transcription of many NBS-LRR family genes was affected by changes in DNA methylation, suggesting that DNA methylation plays essential roles in the response of rice to M. oryzae infection. More broadly, the DNA methylation analysis presented here sheds light on epigenomic involvement in plant defense against fungal pathogens.

Abstract ：
稻飞虱是水稻主要害虫,能够传播多种水稻病毒,严重威胁亚洲水稻生产.稻飞虱主要包括灰飞虱、褐飞虱和白背飞虱.灰飞虱传播水稻黑条矮缩病毒和水稻条纹病毒,褐飞虱传播水稻齿叶矮缩病毒和水稻草矮病毒,白背飞虱传播南方水稻黑条矮缩病毒.本文介绍了3种稻飞虱的基本特性及5种水稻病毒的基因功能和致病特征,详细阐述了稻飞虱与水稻病毒的互作机制,总结了病毒在稻飞虱体内的传播路线及传播障碍,为综合防控稻飞虱传播的水稻病毒病提供参考.
