About 88.1% cDNA fragment are expressed in all the four samples,11.9% are different between the samples. 68 cDNA fragments were cloned, of which 35 weresubject to sequence analysis. Database searches indicate that 11 cDNA fragment show highhomology to known genes, which mainly include proteins related to ion transport, signaltransduction and oxidative stress. The remaining 24 cDNA show no detectable homology toknown genes, suggesting that they probably represent novel genes.展开更多
