| 摘 要： | 采用抑制消减杂交(SSH)技术构建了高羊茅"猎狗5号"低温下的正向差减cDNA文库,并从基因表达水平研究了低温诱导对高羊茅抗寒性的影响.通过Reversenorthern杂交法筛选,挑选出36个低温处理下差异表达基因,并对这些基因进行测序.将测序结果在基因组数据库(NCBI)中进行检索比对,最后获得34个差异表达的基因,其中33个基因功能已知,主要与植物信号转导、光合作用、糖代谢、物质运输以及抗逆性相关.

| Abstract: | A forward subtractive cDNA library was constructed from tall fescue "Houndog 5" cultivar exposed to low temperature stress via suppression subtractive hybridization (SSH). Then cold-resistance of tall fescue (induced by low temperaturing) was determined through genes expression analysis. A total of 36 ESTs from SSH-cDNA library were selected and sequenced after reverse northern hybridization screening. The sequencing results were analyzed by means of retrieval and alignment in unigene GeneBank database. Based on the analysis, 34 genes exhibited different expressions, of which the functions of 33 genes were known and identified. These functionally known genes were detected in signal transduction, photosynthesis, sugar metabolism, material transportation and stress resistance. |
