为探明植物核苷磷酸化酶家族基因信息及生理功能,采用 PCR 扩增的方法,研究了模式植物拟南芥核苷磷酸化酶家族基因在不同组织中的表达,并对其核苷磷酸化酶基因 T-DNA 插入突变体进行鉴定。结果表明:At4g24340和 At4g28940基因在根组织中大量转录表达,其他组织均微量检测到转录表达;At4g24350在各个组织中均有少量转录表达;经 T-DNA 插入结合转录表达鉴定,At4g28940和 At 4g24350基因为敲除突变体。
為探明植物覈苷燐痠化酶傢族基因信息及生理功能,採用 PCR 擴增的方法,研究瞭模式植物擬南芥覈苷燐痠化酶傢族基因在不同組織中的錶達,併對其覈苷燐痠化酶基因 T-DNA 插入突變體進行鑒定。結果錶明:At4g24340和 At4g28940基因在根組織中大量轉錄錶達,其他組織均微量檢測到轉錄錶達;At4g24350在各箇組織中均有少量轉錄錶達;經 T-DNA 插入結閤轉錄錶達鑒定,At4g28940和 At 4g24350基因為敲除突變體。

To explore information and physiological function of nucleoside phosphorylase genes,by using PCR method,the authors examined gene expression of nucleoside phosphorylase in different tissues of model plant arabidopsis, and further screened T-DNA-inserted mutants of these genes. Results:Transcriptional expression of At4g28940 and At4g28940 is high in root tissues ,and slight transcript levels are detected in other tissues ,while At4g24350 gene expression is low in various tissues .After the identification of T-DNA insertion and transcriptional levels of the genes ,the knockout mutants of At4 g28940 and At4 g24350 have been attained in this study .
