title: Differentially expressed genes of Chenopodium amaranticolor in response to cymbidium mosaic virus infection.
abstract: Cymbidium mosaic virus (CymMV)-induced expressed sequence tag (EST) clones from Chenopodium amaranticolor were identified. CymMV was mechanically inoculated onto C. amaranticolor, and local lesion symptoms were observed. Inoculated leaves were collected on serial days post inoculation (dpi) to identify activated or suppressed genes. mRNA isolation and suppression subtractive hybridization (SSH) were then performed to identify differentially expressed genes related to the local lesion response. Fifty-three ESTs, including genes related to defense and stress responses (e.g., lipoxygenase, jasmonate-induced protein, and heat shock protein), were generated. In addition, a large proportion of the ESTs were found to be involved in photosynthesis, as determined by their functional categories. Expression levels of several EST genes were observed using quantitative real-time reverse transcription-polymerase chain reaction, and the evaluated genes showed varying levels of expression during the experimental period. In this study, differentially expressed sequences via SSH were identified from CymMV-infected C. amaranticolor, and profiling and annotation were carried out to determine the expression pattern of CymMV and its interaction with C. amaranticolor.
