Taste has been the subject of human selection in the evolution of agricultural crops, and acidity is one of the three major components of fleshy fruit taste, together with sugars and volatile flavour compounds. We identify a family of plant-specific genes with a major effect on fruit acidity by map-based cloning of C. melo PH gene (CmPH) from melon, Cucumis melo taking advantage of the novel natural genetic variation for both high and low fruit acidity in this species. Functional silencing of orthologous PH genes in two distantly related plant families, cucumber and tomato, produced low-acid, bland tasting fruit, showing that PH genes control fruit acidity across plant families. A four amino-acid duplication in CmPH distinguishes between primitive acidic varieties and modern dessert melons. This fortuitous mutation served as a preadaptive antecedent to the development of sweet melon cultigens in Central Asia over 1,000 years ago. © 2014 Macmillan Publishers Limited.

Manufacturing industry has been progressively using digital planning tools for product development and manufacturing to handle product and process complexity and to react to ever-increasing cost and time pressure. Based on the current need for action, this paper presents the future development potentials of digital planning support in the framework of Product Lifecycle Management. Therefore, it describes basic approaches for intelligent use of tacit knowledge in digital factory using the example of time data. © Carl Hanser Verlag, München.

Mutual cross-linkages cause an enhancement of mechatronic to cybertronic products (CTP) and production systems (CTPS). This paper deals with a framework for a model based, integrated development of CTP and CTPS. It is based on the V-model according to VDI guideline 2206 and gets enhanced by methods of virtual product development as well as model based systems engineering. © GITO Verlag.
