蜜蜂(Apis mellifera)表现出丰富的行为、社会组织和种姓分化,并具有有趣的性别决定模式,但我们对其潜在的遗传程序知之甚少。我们在蜜蜂中缺乏稳定的转基因工具,这将允许在稳定的转基因品系中对基因活性进行遗传控制。作为转基因方法的第一步,我们在蜜蜂中鉴定了可以驱动组成型、组织特异性和冷休克诱导的基因表达的启动子序列。我们鉴定了Am ‐actin5c、elp2l、Am‐ hsp83和Am ‐ hsp70的启动子序列,并表明除了elp2l序列外,所鉴定的序列能够驱动Sf 21细胞中的报告基因表达。我们通过电穿孔实验进一步证明了假定的神经元特异性elp2l启动子序列可以指导蜜蜂大脑中的基因表达。这些启动子序列的鉴定是通过蜜蜂转基因实验研究基因功能的重要第一步,蜜蜂是一种具有丰富有趣表型的生物体。
The honey bee,Apis mellifera, displays a rich behavioural repertoire, social organization and caste differentiation, and has an interesting mode of sex determination, but we still know little about its underlying genetic programs. We lack stable transgenic tools in honey bees that would allow genetic control of gene activity in stable transgenic lines. As an initial step towards a transgenic method, we identified promoter sequences in the honey bee that can drive constitutive, tissue‐specific and cold shock‐induced gene expression. We identified the promoter sequences ofAm‐actin5c,elp2l,Am‐hsp83andAm‐hsp70and showed that, except for theelp2lsequence, the identified sequences were able to drive reporter gene expression inSf21 cells. We further demonstrated through electroporation experiments that the putative neuron‐specificelp2lpromoter sequence can direct gene expression in the honey bee brain. The identification of these promoter sequences is an important initial step in studying the function of genes with transgenic experiments in the honey bee, an organism with a rich set of interesting phenotypes.
