Fruit softening is the major factor determining the postharvest life of fruit, affecting bruise and damage susceptibility, pathogen colonisation, and consumer satisfaction, all of which contribute to product losses in the supply chain and consumers' homes. Ripening-related changes to the cell wall, cuticle and soluble sugars largely determine softening, and some are amenable to biotechnological intervention, for example, by manipulation of the expression of genes encoding cell wall-modifying proteins or wax and cutin synthases. In this review, we discuss work exploring the role of genes involved in cell wall and cuticle properties, and recent developments in the silencing of multiple genes by targeting single transcription factors. Identification of transcription factors that control the expression of suites of genes encoding cell wall-modifying proteins provides exciting targets for biotechnology.
果实软化是决定果实采后寿命的主要因素，影响果实对擦伤和损伤的易感性、病原体定植以及消费者满意度，所有这些都会导致供应链和消费者家中的产品损失。与成熟相关的细胞壁、角质层和可溶性糖的变化在很大程度上决定了果实软化，其中一些变化适合生物技术干预，例如，通过操纵编码细胞壁修饰蛋白或蜡质和角质合成酶的基因的表达。在本综述中，我们讨论了探索参与细胞壁和角质层特性的基因作用的研究工作，以及通过靶向单个转录因子使多个基因沉默的最新进展。鉴定控制编码细胞壁修饰蛋白的基因组合表达的转录因子为生物技术提供了令人兴奋的靶点。
