Summary: In this study, the color conversion mechanism of pepper fruit was explored using transcriptome and metabolome analysis. Key genes and metabolites involved in the biosynthesis of flavonoids and carotenoids were identified, and their roles in pepper fruit color changes were revealed. Transcription factor families such as p450 and NBARC were also found to potentially play important roles in the biosynthesis of flavonoids and carotenoids in pepper fruits.

Summary: Organoleptic properties are crucial for determining peach fruit quality, with sugar and acid levels driving the range of fruit taste in spite of a narrow genetic diversity. This study identified malate and citrate as the most abundant organic acids in peaches, contributing significantly to overall acidity. Results also showed genotype-dependent contributions of specific organic acids and minimal seasonality effects on peach acidity and organic acid patterns, providing valuable insights for ongoing breeding programs.

Summary: In this study, a germplasm collection of 116 sweet cherry accessions was evaluated for 23 agronomic fruit quality traits over 2-6 years. The researchers identified numerous SNP-trait associations for various fruit quality traits and pinpointed several candidate genes involved in phytohormone, calcium, and cell wall metabolisms. A literature review was conducted to compare the results with potential colocalizations of marker-trait associations. This study provides new knowledge on the genetic control of important agronomic traits related to fruit quality.

Summary: One hundred accessions of Diplotaxis tenuifolia and Eruca spp. were screened for resistance to downy mildew. Cultivated rocket accessions showed a resistant response, while wild rocket accessions exhibited higher susceptibility in cotyledons. There was a significant correlation between disease index in cotyledons and leaves. Molecular markers analysis revealed genetic distance between Diplotaxis and Eruca, along with diverse interactions with the pathogen. Future studies will focus on evaluating different responses under greenhouse or field production and genome mapping of downy mildew resistance-related genetic features.

Summary: This study conducted reciprocal crosses between different inbred varieties of chili peppers and found significant differences in agronomic and fruit traits as well as heterosis and reciprocal effects. Restoring fertility by pollination of hybrids with parental pollen was effective in modifying fruit size and shape, with differential effects depending on the pollen source used. The results highlight the importance of combining parental genotypes and the optimal crossing direction in driving phenomena like heterosis, yield, and fruit morphology.

Summary: The aim of this study was to develop a method for creating and validating CRISPR-Cas systems and different gRNAs in soybean embryos. Two model genes were used for simple mutation and partial gene deletion. The gRNAs were inserted into the CRISPR transformation vectors using type IIS restriction enzyme or classic restriction enzyme cloning method. One and two gRNAs were successfully constructed. The CRISPR-Cas system and gRNAs were confirmed to be functional through enzyme digestion, polymerase chain reaction, and sequencing in transformed embryos.
