Eggplant is an economically important vegetable crop in Asia and Africa, and although it is grown in Europe and the United States, it does not account for a significant percentage of agricultural production. It is susceptible to a number of pathogens and insects, with bacterial and fungal wilts being the most devastating. Attempts to improve resistance through introgression of traits from wild relatives have had limited success owing to sexual incompatibilities. Therefore, a crop improvement approach that combines both conventional breeding and biotechnological techniques would be beneficial. This chapter describes an Agrobacterium-mediated transformation protocol for eggplant based on inoculation of seedling explants (cotyledons and hypocotyls) and leaves. We have used this protocol to recover transformants from two different types of eggplant, a Solanum melongena L. breeding line, and S. melongena L. var. Black Eggplant. The selectable marker gene used was neomycin phosphotransferase II (nptII) and the selection agent was kanamycin. In vitro grown transformants acclimated readily to greenhouse conditions.
茄子是亚洲和非洲一种具有重要经济价值的蔬菜作物,虽然在欧洲和美国也有种植,但在农业生产中所占比例不大。它易受多种病原体和昆虫侵害,其中细菌性和真菌性枯萎病危害最大。由于存在有性不亲和性,通过导入野生近缘种的性状来提高抗性的尝试成效有限。因此,将传统育种和生物技术相结合的作物改良方法将是有益的。本章介绍了一种基于接种幼苗外植体(子叶和下胚轴)和叶片的农杆菌介导的茄子转化方案。我们已使用该方案从两种不同类型的茄子(一种茄子栽培品种和黑茄子变种)中获得转化体。所用的选择标记基因是新霉素磷酸转移酶II(nptII),选择剂是卡那霉素。在体外培养的转化体很容易适应温室条件。
