Advances in S gene targeted genome-editing and its applicability to disease resistance breeding in selected crop plants.

Genome-editing tools for the development of traits to tolerate abiotic and biotic adversaries are the recently devised breeding techniques revolutionizing molecular breeding by addressing the issues of rapidness and precision. To that end, disease resistance development by disrupting disease susceptibility genes (S genes) to intervene in the biological mechanism of pathogenicity has significantly improved the techniques of molecular breeding. Despite the achievements in genome-editing aimed at the intervention of the function of susceptibility determinants or gene regulatory elements, off-target effects associated with yield-related traits are still the main setbacks.

The red or purple color of radish ( L.) taproots is due to anthocyanins, which have nutritional and aesthetic value, as well as antioxidant properties. Moreover, the varied patterns and levels of anthocyanin accumulation in radish roots make them an interesting system for studying the transcriptional regulation of anthocyanin biosynthesis.

Identification of α-Glucosidase Inhibitors from Leaf Extract of Pepper ( spp.) through Metabolomic Analysis.

Metabolomics and in vitro α-glucosidase inhibitory (AGI) activities of pepper leaves were used to identify bioactive compounds and select genotypes for the management of type 2 diabetes mellitus (T2DM). Targeted metabolite analysis using UPLC-DAD-QToF-MS was employed and identified compounds that belong to flavone and hydroxycinnamic acid derivatives from extracts of pepper leaves. A total of 21 metabolites were detected from 155 samples and identified based on MS fragmentations, retention time, UV absorbance, and previous reports.

Evaluation of Dynamic Properties of Sodium-Alginate-Reinforced Soil Using A Resonant-Column Test.

Ground reinforcement is a method used to reduce the damage caused by earthquakes. Usually, cement-based reinforcement methods are used because they are inexpensive and show excellent performance. Recently, however, reinforcement methods using eco-friendly materials have been proposed due to environmental issues.

QTL Mapping for Gummy Stem Blight Resistance in Watermelon ( spp.).

Watermelon () is an economically important fruit crop worldwide. Gummy stem blight (GSB) is one of the most damaging diseases encountered during watermelon cultivation. In the present study, we identified quantitative trait loci (QTLs) associated with GSB resistance in an F population derived from a cross between maternal-susceptible line '920533' () and the paternal-resistant line 'PI 189225' ().

Identification of QTLs Controlling α-Glucosidase Inhibitory Activity in Pepper ( L.) Leaf and Fruit Using Genotyping-by-Sequencing Analysis.

Diabetes mellitus, a group of metabolic disorders characterized by hyperglycemia, is one of the most serious and common diseases around the world and is associated with major complications such as diabetic neuropathy, retinopathy, and cardiovascular diseases. A widely used treatment for non-insulin-dependent diabetes is α-glucosidase inhibitors (AGIs) such as acarbose, which hinders hydrolytic cleavage of disaccharides and retard glucose absorption. The ability to inhibit α-glucosidase activity has been reported in leaf and fruit of pepper ( L.

Construction of an Onion ( L.) Genetic Linkage Map using Genotyping-by-Sequencing Analysis with a Reference Gene Set and Identification of QTLs Controlling Anthocyanin Synthesis and Content.

Anthocyanins, the pigmented flavonoids responsible for red and blue colors in horticultural products, promote human health by preventing cancers and lowering the risk of cardiovascular disease. Red onions contain several cyanidin- and peonidin-based anthocyanins. In this study, we constructed a single-nucleotide polymorphism (SNP)-based genetic linkage map in an F segregating population derived from a cross between the inbred line 'SP3B' (yellow bulb) and the doubled haploid line 'H6' (red bulb) to identify quantitative trait loci (QTLs) for total anthocyanin content of onion bulbs using a genotyping-by-sequencing (GBS) analysis based on a reference gene set.

Linkage analysis between the partial restoration (pr) and the restorer-of-fertility (Rf) loci in pepper cytoplasmic male sterility.

Cytoplasmic male sterility (CMS) in chili pepper is restored by one major dominant nuclear gene, restorer-of-fertility (Rf), together with some modifier genes and is also affected by temperature. As a result, male fertility was identified as having several phenotypes. That identified and used in the present study allowed partial restoration of fertility, producing plants that simultaneously produce normal and aborted pollen grains, with most grains stuck to the anther wall, even after dehiscence, resulting in low seed set per fruit.
