Fruits provide humans with multiple kinds of nutrients and protect humans against worldwide nutritional deficiency. Therefore, it is essential to understand the nutrient composition of various fruits in depth. In this study, we performed LC-MS-based non-targeted metabolomic analyses with ten kinds of fruit, including passion fruit, mango, starfruit, mangosteen, guava, mandarin orange, grape, apple, blueberry, and strawberry. In total, we detected over 2500 compounds and identified more than 300 nutrients. Although the ten fruits shared 909 common-detected compounds, each species accumulated a variety of species-specific metabolites. Additionally, metabolic profiling analyses revealed a constant variation in each metabolite’s content across the ten fruits. Moreover, we constructed a neighbor-joining tree using metabolomic data, which resembles the single-copy protein-based phylogenetic tree. This indicates that metabolome data could reflect the genetic relationship between different species. In conclusion, our work enriches knowledge on the metabolomics of fruits, and provides metabolic evidence for the genetic relationships among these fruits.

Drought is a major abiotic stress limiting rice production worldwide. GA2ox3, a GA 2-oxidase involved in gibberellin deactivation, has been previously linked to growth regulation. Here, we demonstrate that functional disruption of GA2ox3 enhances shoot growth but compromises drought tolerance in rice. CRISPR/Cas9 knockout lines (ga2ox3) showed increased plant height and reduced antioxidant capacity under 20%PEG-induced osmotic stress, evidenced by higher H₂O₂ and MDA accumulation and decreased POD activity. Moreover, expression analysis revealed that GA2ox3 may be associated with the GA signaling cascade involving OsSLR1, OsBURP3, and OsSUS1. Haplotype analysis based on 627 rice accessions identified two major alleles, Hap1 and Hap2, with Hap1 showing higher GA2ox3 expression and stronger drought resilience. These findings suggest that GA2ox3 positively regulates osmotic stress tolerance, and its natural variation represents promising genetic resources for improving drought adaptation in rice.
