To screen out the bio-control soil microorganisms for preventing melon wilt, soil microbial compositions in rhizospheres between wilt-resistant and susceptible melon varieties were analyzed. The results showed that the soil fungal richness in rhizospheres of wilt-resistant melon varieties (MT) was significantly higher than that of wilt-susceptible melon varieties (MS). Additionally, in comparison with MS, soil bacterial compositions, such as Proteobacteria, Bacteroidota, , etc., and the soil fungal compositions, such as , , , and , enriched; also, , , and decreased in rhizospheres of wilt-resistant melon varieties (MT). Moreover, , , and were the unique soil-dominant fungal genera in rhizospheres of MT. All the above results suggested that the soil bacterial communities, such as Proteobacteria, Bacteroidota, Acidibacter, , etc., and the soil fungal communities, such as , , , , , and , could be speculated as the potential soil bio-control microorganisms for preventing melon wilt.

Background: Sugars are not only important biomacromolecules that play vital roles in plant growth, development and environmental stress tolerance, but they also provide carbon skeletons for the synthesis of other macromolecules, such as proteins and nucleic acids. Sugar-related proteins play key roles in the movement of sugars from source tissues (such as leaves) to sink tissues (such as fruits), ultimately influencing fruit development. However, the evolutionary dynamics of this important sugar-related gene family in the Cucumis melo (C.

Fruits are an important source of a healthy diet due to their essential nutrients for daily intake. Melon is known as a significant fruit crop of the Cucurbitaceae family based on its various dietary benefits, but its shelf life needs to be maintained for long-term usage. 1-Methylcyclopropene (1-MCP) is a cyclopropene-derived synthetic plant growth regulator (PGR) that is used for significantly delaying the ripening process and maintaining the shelf life of climacteric fruits during storage.
