Fruit plays a crucial role in healthy nutrition and human well-being by providing essential vitamins and minerals. However, the rapid expansion of the fruit industry coupled with changing climate conditions poses significant challenges to fruit tree cultivation. These challenges include various biotic stresses such as pests and diseases (bacterial, fungal and viral) and abiotic stresses such as drought and salinity. Developing resilient fruit tree varieties through rigorous screening and breeding processes is essential but is hampered by long breeding cycles, high costs and inefficiencies in hybridization.

Recent advances in multi-omics and molecular breeding open promising new opportunities for fruit tree breeding. These technologies facilitate the study of physiological and biochemical processes and enable the identification of genes linked to economically important traits and resistance mechanisms.

This Research Topic aims to evaluate the quality, resilience and other important traits of fruit trees to identify superior breeding material. The main objective is to uncover the formation and molecular mechanisms underlying critical traits in response to biotic and abiotic stresses. By achieving these objectives, this Research Topic will provide valuable resources and guidelines for breeding high-quality, resilient fruit tree varieties. Contributions on various fruit tree species, including citrus, grapes, peaches, kiwis, pears, apples and others, are welcome.

We encourage submission of original research articles and reviews on this Research Topic, including but not limited to the following subtopics:

• Physiological, biochemical and molecular responses of fruit trees to biotic and abiotic stresses.
• Multi-omics approaches to decipher plant-pathogen interactions and stress responses.
• Achievements in tools, technologies and resources for environmental adaptation in fruit tree breeding, including genome editing.
• Effects of nutrient deficiency stress on the development and quality of fruit trees.
• New insights into the influence of light on fruit development.
