Special Issue Information

Dear Colleagues,

This Special Issue titled "Advances in Gene Regulation and Genetic Improvement of Fruit Trees" aims to explore the latest developments and advancements in gene regulation techniques and genetic improvement strategies specifically focused on fruit trees. Fruit trees play a crucial role in agriculture and horticulture, providing essential nutrients and contributing to the economy. Therefore, understanding their underlying genetic mechanisms and finding ways to improve fruit tree traits are of great importance.

This Special Issue invites researchers and experts in the field to contribute their original research articles, reviews, and perspectives on topics such as gene regulation, genetic engineering, and breeding techniques applied to fruit trees. The goal is to provide a comprehensive overview of the recent progress in understanding gene regulation and its impact on fruit tree improvement.

The articles featured in this Special Issue will cover a wide range of fruit tree species, including but not limited to apples, pears, peaches, grapes, oranges, and cherries. They will delve into the molecular mechanisms involved in gene regulation, exploring how specific genes impact fruit quality, yield, disease resistance, and other desirable traits. Additionally, advancements in genetic engineering techniques, such as CRISPR/Cas9, and their potential applications in fruit tree improvement will be discussed.

Overall, this Special Issue will serve as a valuable resource for researchers, breeders, and professionals in the field of fruit tree genetics and breeding. It will contribute to the advancement of knowledge and provide insights into new strategies for enhancing fruit tree productivity and quality through gene regulation and genetic improvement.

Ridging cultivation and root restriction cultivation are beneficial due to their improvement of the soil permeability in the root zone of grapevine, and they are widely used in southern China, Japan, and other countries. However, with the intensification of global warming, when using ridging or root restriction cultivation, the soil temperature in the root zone can often reach 30 °C or even more than 35 °C during the summer, which is not conducive to the growth of grapevines. The aim of this study was to explore the effects of high root zone temperatures on the photosynthetic fluorescence characteristics of grapevine leaves, root respiration, and degree of lignification of roots and shoots, as well as to provide a theoretical foundation for the management of grapevine production and cultivation. One-year-old potted ‘Kyoho’ was used as the study material. Three root temperature treatments were implemented for 15 days (9:00–16:00): 25 °C (CK), 30 °C (T1), and 35 °C (T2). The results showed that the malondialdehyde and H2O2 levels in leaves increased, while the chlorophyll content decreased. The oxygen-evolving complex was inactivated, and PSII donor and acceptor sides were blocked, thus reducing the photosynthetic gas exchange capacity at high root zone temperatures. The grapevine root activity and root/shoot ratio decreased. Simultaneously, the lignin content in the roots and shoots increased. In addition, there was a significant increase in the expression of key genes (PAL, C4H, 4CL, F5H, COMT, CCR, and CAD) in the root lignin synthesis pathway. Heightened root zone temperatures increased cyanide-resistant respiration in roots and heat release in the PPP pathway to alleviate stress damage. Therefore, it is recommended to use grass, mulching, and other cultivation management methods to maintain root zone temperatures below 30 °C in order to ensure the normal growth of grapevines and promote a high and stable yield.
