摘要 启动子是位于基因 5′端并负责该基因转录的DNA序列。诱导性启动子中有一些对伤害、真菌侵染、紫外线照射、激素等做出应答反应的顺式作用元件 ,被称为模序。已在植物启动子中鉴定出许多与诱导表达相关的模序 ,如伤害诱导模序 ,真菌诱导模序 ,植物激素诱导模序和光诱导模序等。这些模序作为启动子的顺式元件对各种诱导因子做出反应、调控基因的表达。 Many motifs of plant inducible promoters have been identified such as wound-inducible motifs, fungal-inducible motifs, light-inducible motifs and plant hormone-inducible motifs responsive to methyl jasmonate (MeJA), abscisic acid (ABA) and ethylene. These motifs function as cis-elements that are responsive to corresponding elicitors to regulate the expression of genes.
