|a Frequent cold spells in late spring can damage early rice seedlings. However, overexpression of the silicon-uptake gene Lsi1 (Lsi1-OX) in cold-sensitive rice (Oryza sativa L., accession: Dular) notably enhances its chilling resistance. In this study, we found that continual chilling led to chlorophyll and RNA degradation in wild-type Dular leaves, whereas leaves from a Lsi1-OX line exhibited no obvious changes. A comparison of the global mRNA expression between the two rice lines showed that genes encoding photosynthesis-antenna proteins were downregulated and those encoding the proteasome were upregulated in the wild-type organism. Moreover, the differential responses of the two rice lines to chilling stress were found to correlate with the transcription factor OsWRKY53, which was predicted target of the respective microRNA (miRNA) novel-m0586-5p. In addition, miRNAs that targeted genes involved in the process of reactive oxygen species (ROS) metabolism were differentially expressed in the two rice lines after chilling stress, when comparative analysis of the outcomes of RNA sequencing on the two rice lines. Our results suggest that when overexpressed Lsi1 in cold-sensitive rice, it possibility regulates the transcription factor OsWRKY53 in addition to the genes involved in the ROS metabolism, thus mediating resistance to chilling stress
