Summary: This study evaluated the genetic diversity and structure of 24 A. chinensis populations and found high levels of genetic diversity in the polyploid populations. The study also revealed distinct eastern and western genetic clusters. Ecological niche modeling predicted a gradual loss of potentially suitable areas for tetraploids and increasing habitat fragmentation in the future.

Summary: This study investigates the genetic basis of early blight resistance in potato by using hybridization and field trials. Several quantitative trait loci (QTL) associated with early blight resistance were identified, providing new insights for marker-assisted selection in breeding for early blight resistance.

Summary: This study successfully induced stable gene knock-out of the SyGI gene in two tetraploid male accessions of Actinidia chinensis var. chinensis using CRISPR/Cas9 technology, with regenerative efficiencies of 58% and 73%. Although the phenotypic effects on flower structure have not been verified, two regenerated lines with a unique modification in their genome near fixation were obtained.

Summary: This study successfully bred two red-fleshed kiwifruit hybrids with excellent appearance quality through hybridization method. The phenotypes of these hybrids are stably inherited with big and red-fleshed fruit. Analysis results show that both hybrids are rich in flavonoids, carotenoids and vitamin C, making them suitable candidates for new tetraploid kiwifruit varieties.

Summary: This study established a complete pipeline for CRISPR-Cas9-mediated modulation of miRNA expression in potato and found that miRNA editing can result in different types of mutations among transgenic lines and different alleles within the same plant.

Summary: This study investigated the influence of the colour of photo-selective nets on Actinidia deliciosa yield, fruit quality, and the progression of the bacterial kiwifruit canker. The results showed that different colours of nets had a certain impact on yield and fruit quality, with lower yield observed under yellow and grey nets, while the yield and fruit grade under pearl nets were similar to uncovered crops. Photo-selective nets did not significantly affect fruit quality parameters and had a reduced impact on the progression of the bacterial kiwifruit canker in both seasons.

Summary: The use of plant elicitors such as salicylic acid and methyl jasmonate to control Pseudomonas syringae pv. actinidiae has shown contrasting effects, with salicylic acid decreasing disease susceptibility and methyl jasmonate increasing it. This study found that methyl jasmonate increased Psa population while salicylic acid decreased colonization. Additionally, both elicitors led to changes in polyphenols, lignin concentrations, and total proteins in the plants.

Summary: Colchicine-induced polyploidization at 0.1% concentration in Actinidia chinensis resulted in increased plant height, leaf size, biomass, and significantly larger leaf cells in tetraploid plants compared to diploid plants. Transcriptome analysis identified differentially expressed cell wall-related genes, such as PMEs and EXPs, which may contribute to the increased cell size in tetraploid plants. These findings suggest that tetraploidization enhances organ and cell size in kiwifruit by potentially improving cell wall extensibility.

Summary: This study evaluated the variations in yield and nutrient concentrations of 243 diverse tetraploid potato accessions. The results showed that the potato germplasm has a wide range of variations in nutrient concentrations, with higher concentrations found in the peripheral layers of the tubers. Peeling off the tubers resulted in the loss of nutrients, particularly for iron and copper. These findings are important for developing nutrient-rich and high-yielding potato varieties.

Summary: The study found that genotype selection was more effective in winter, and evaluating the third leaf emitted after six months of growth can effectively differentiate between resistant and susceptible genotypes. The improved diploids and tetraploid hybrids showed significant variability in disease resistance, with recommendations to use hybrids with quantitative resistance for cultivation.

Summary: The genetic diversity of 52 kiwifruit wild germplasms was studied using SCoT molecular markers. The genetic relationships were mainly clustered based on place of origin rather than morphological classification or geographical distribution. Disease resistance analysis partially verified the genetic relationships between the wild kiwifruit germplasms.

Summary: The resistance mechanism of microbial communities in contaminated groundwater under the combined stress of sulfonamide antibiotics, NH4+, and Fe-Mn exceeding the standard levels was studied. The study found a complex relationship between microbial communities and environmental factors. After adding sulfonamide antibiotics, Proteobacteria with multi-resistance became the dominant phylum, and Acinetobacter became the dominant genus with SA resistance. Sulfonamide antibiotics significantly influence bacterial chemotaxis, transporters, substance transport, and metabolism.

Summary: By analyzing the metabolic differences between four lines of tetraploid wheat, it was found that certain secondary metabolites involved in plant defense mechanisms increased significantly during wheat domestication, while other defensive metabolites decreased or were lost. These metabolic changes reflect the beneficial or detrimental roles the corresponding metabolites might play during the domestication of three taxonomic subspecies of tetraploid wheat (Triticum turgidum).
