原始语种摘要: Abstract(#br)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...
