Special Issue Information

Dear Colleagues,

Fruit trees are vital for food production and the economy. However, genetic complexity poses a significant hurdle in fruit trees, and their long generation times are a common issue. Moreover, due to the "non-grain production" policy, the lack of stress-tolerant fruit trees has become a bottleneck in the industry. On the positive side, genomic technologies and marker-assisted selection (MAS) have brought about substantial breakthroughs. Furthermore, gene editing technologies are emerging as powerful tools. Breeding has evolved with traditional hybridization and modern gene editing and molecular marker-assisted techniques, speeding up variety development. Genetic studies, through genomics, transcriptomics and metabolomics, identify genes related to beneficial traits. This offers a wealth of knowledge for researchers and growers, propelling the fruit tree industry forward and inspiring further exploration in this essential field. Overall, while fruit tree breeding faces numerous challenges, the continuous development of innovative technologies offers hope for overcoming these obstacles and further advancing the quality and diversity of fruit tree varieties.

This Special Issue aims to collect articles on the latest advances in gene editing technologies and the physiology and breeding of fruit trees. Original research articles and reviews in this area are also welcome. All article submissions should involve research at the molecular level as well as verified experiments.

Kiwifruit, with its unique flavor, nutritional value, and economic benefits, has gained significant attention in agriculture production. Kiwifruit plants have traditionally been propagated without grafting, but recently, grafting has become a more common practice. A new and complex disease called Kiwifruit Vine Decline Syndrome (KVDS) has emerged in different kiwifruit-growing areas. The syndrome was first recognized in Italy, although similar symptoms had been observed in New Zealand during the 1990s before subsequently spreading worldwide. While kiwifruit was not initially grafted in commercial orchards, the expansion of cultivation into regions with heavy soils or other challenging environmental conditions may make grafting selected kiwifruit cultivars onto KVDS-resistant or -tolerant rootstocks essential for the future of this crop. Grafting is a common horticultural practice, widely used to propagate several commercially important fruit crops, including kiwifruits, apples, grapes, citrus, peaches, apricots, and vegetables. Grafting methods and genetic compatibility have a crucial impact on fruit quality, yield, environmental adaptability, and disease resistance. Achieving successful compatibility involves a series of steps. During grafting, some scion/rootstock combinations exhibit poor graft compatibility, preventing the formation of a successful graft union. Identifying symptoms of graft incompatibility can be challenging, as they are not always evident in the first year after grafting. The causes of graft incompatibility are still largely unknown, especially in the case of kiwifruit. This review aims to examine the mechanisms of graft compatibility and incompatibility across different fruit crops. This review’s goal is to identify potential markers and techniques that could enhance grafting success and boost the commercial production of kiwifruit. Full article
