摘　　要：采用Clontech公司SMARTTM技术,分别构建了家蚕4龄眠蚕后部丝腺(PSG0)以及5龄第3天后部丝腺(PSG3)、中部丝腺(MSG3)和脂肪体(FAT3)的Matchmaker cDNA文库,用A3基因引物对几个文库的质量进行了检测;从cDNA文库和家蚕基因组中克隆了FMBP-1、POU-M1和BmFkh 3种在蚕丝蛋白基因表达调控中起重要作用的转录因子编码区,并对其序列进行了分析。结果表明,所建cDNA文库能够用于利用酵母的杂交系统开展蚕丝蛋白基因的表达调控研究。Using SMART^TM cDNA library construction technology from Clontech biocompany, we have constructed 4 Matchmaker cDNA libraries for posterior silk gland of 4^th moulting larvae, posterior silk gland, middle silk gland and fat body of larvae at 3^rd day of 5^th instar, respectively. Quality of the libraries was checked using A3 gene specific primers. CDSs of 3 main trans factors involved in controlling silk genes＇ expression were cloned and sequenced from the libraries and silkworm genomic DNA. Results showed that these libraries can be used in the study of silk genes＇ controlling using yeast hybrid technology.
