摘要: 利用抑制差减杂交(Suppression subtractive hybridization,SSH)技术分离玉米低锌与正常供锌条件下表达有差异的cDNA片段。以低锌培养的玉米幼苗为试验方,正常供锌的玉米幼苗为对照方,建立正向差减文库;以正常供锌的玉米幼苗为试验方,以低锌诱导培养的玉米幼苗为对照方,建立反向差减文库。正、反向文库分别收集低锌和正常供锌条件下特异表达的cDNA片段。在2个文库中,各随机挑选30个克隆进行测序。序列分析表明,在正向差减文库中,分离得到的基因多与抗病防御、信号转导、细胞生长与分裂等方面相关;在反向差减文库中,分离得到的基因多与细胞组织发生及代谢等方面有关。

Abstract: Suppression subtractive hybridization (SSH) was performed to isolate the differentially expressed cDNA fragments under low-zinc and zinc-sufficiency conditions. In the forward subtracted library, the cDNA of maize seedlings treated with low-zinc was used as tester and the cDNA of maize seedlings treated with zinc-sufficiency was used as driver. In the reverse subtracted library, the cDNA of maize seedlings treated with zinc-sufficiency was used as tester and the cDNA of maize seedlings treated with low-zinc was used as driver. The cDNA fragments differentially expressed under low-zinc and zinc-sufficiency conditions were collected in the forward and reverse subtracted library, respectively. Thirty clones were randomly picked to sequence in each library. The sequencing results shows: the function of isolated genes in the forward subtracted library mostly relates to disease resistance/defense, signal transduction, cell growth/division and so on. While the function of isolated genes in the reverse subtracted library mostly relates to cell/tissue generation, metabolism and so on.

Key words: Suppression subtractive hybridization, Maize, Low-zinc
