The genus includes one of the 10 most agronomically and economically important plant groups in the world. Within this group, we can find examples such as broccoli, cabbage, cauliflower, kale, Brussels sprouts, turnip or rapeseed. Their cultivation and postharvest are continually threatened by significant stresses of biotic origin, such as pathogens and pests. In recent years, numerous research groups around the world have developed transgenic lines within the genus that are capable of defending themselves effectively against these enemies. The present work compiles all the existing studies to date on this matter, focusing in a special way on those of greater relevance in recent years, the choice of the gene of interest and the mechanisms involved in improving plant defenses. Some of the main transgenic lines developed include coding genes for chitinases, glucanases or cry proteins, which show effective results against pathogens such as , or , or pests such as or .
该属包含世界上10个在农业和经济方面最重要的植物类群之一。在这个类群中，我们可以找到西兰花、卷心菜、花椰菜、羽衣甘蓝、抱子甘蓝、芜菁或油菜籽等例子。它们的种植和收获后过程不断受到生物源重大胁迫的威胁，如病原体和害虫。近年来，世界各地的众多研究团队已在该属内培育出能够有效抵御这些敌人的转基因品系。本研究汇编了迄今为止关于此事的所有现有研究，特别关注近年来更具相关性的研究、目标基因的选择以及参与增强植物防御的机制。已培育出的一些主要转基因品系包括几丁质酶、葡聚糖酶或cry蛋白的编码基因，这些基因对诸如 、 或 等病原体，或诸如 或 等害虫显示出有效的防治效果。
