The transcript was increased 6 h after sprayed with the safener solution, and 4 days later, the expression still could be detected. The fragment was recycled from the polygel and sequenced, and homologous analysis revealed the cDNA was 100% identical to some ESTs and cDNAs in rice database, and the amino acid sequence was 60-84% homologous to those of the Yippee genes in several eukaryotes. The fragment was extended to the whole long cDNA, and thus a primer pair was designed. RT-PCR analysis for the designed primer supported the induction result.展开更多
