| 摘 要： | 从水稻基因组DNA中扩增出1 184 bp的Ospgip1基因片段。该片段包含930 bp的完整开放阅读框，终止密码子为TAA，无内含子。RT PCR结果表明，Ospgip1基因在水稻抗、感纹枯病品种中均能表达，但不同生育期、不同部位表达量有差异。实时PCR结果显示，抗病品种YSBR1和中感品种Jasmine 85中Ospgip1的表达量要明显高于感病品种Lemont；稻苗黄化处理后，无论是抗病品种还是感病品种的Ospgip1表达量均显著提高；纹枯病菌侵染使得抗病品种Ospgip1表达量大大增加，而对感病品种影响不大。 |

| Abstract: | A fragment of 1 184 bp of the Ospgip1 gene including a complete open reading frame(OFR) of 930 bp had been amplified,which had the termination codon of TAA and no intron.RT-PCR results showed that the Ospgip1 gene could be expressed in all the rice cultivars while their expression levels differed among growth stages or organs.Real-time PCR results indicated that the expression levels in resistant cultivars YSBR1 and Jasmine 85 were significantly higher than that in the susceptible cultivar Lemont.The expression level was also upregulated in the etiolated seedlings.Inoculation with the pathogen of rice sheath blight significantly upregulated the expression level of the Ospgip1 gene in resistant cultivars while exerted no impact on the expression level of the gene in the susceptible one. |
