An ultra-dense linkage map identified quantitative trait loci corresponding to fruit quality- and size-related traits in red goji berry.

Goji berries are a small-fruited shrub with industrial importance whose fruit considered beneficial in both fresh and dried forms. Current germplasms of goji berries include small fruits with a short shelf life, less sweet and bitter taste, and a lack of appropriate genetic information. This study aimed to employ whole genome resequencing to generate an ultra-dense bin linkage map and to elucidate the genetic basis of goji fruit quality and size using quantitative trait loci (QTL) mapping analysis in a cross-pollinated hybrid population.

The complete plastome of (Apocynaceae), an indigenous plant in Korea.

The climbing plant (Turcz.) Liede & Khanum is widely distributed throughout Korea and Northeast Asia as a member of the Apocynaceae family. Although this plant has a high value in medicinal and industrial purposes, genetic research on this plant is insufficient.

Germplasm Resources and Strategy for Genetic Breeding of Species: A Review.

species (goji), belonging to Solanaceae, are widely spread in the arid to semiarid environments of Eurasia, Africa, North and South America, among which most species have affinal drug and diet functions, resulting in their potential to be a superior healthy food. However, compared with other crop species, scientific research on breeding species lags behind. This review systematically introduces the present germplasm resources, cytological examination and molecular-assisted breeding progress in species.

Discrimination of Geographical Origins of Wolfberry ( L.) Fruits Using Stable Isotopes, Earth Elements, Free Amino Acids, and Saccharides.

To develop sophisticated approaches for distinguishing goji origins, 325 wolfberry fruit samples of a certain cultivar, plant age, drying method, and collection season were gathered from 26 producing areas across Northwest China in 2017 and 2018. We employed 49 indices, including stable isotopes, earth elements, soluble amino acids, and saccharides, to identify the regions of origin of these goji fruits. Analysis of variance (ANOVA) and heritability analysis were used to assess the effects of the environment (producing areas), cultivar, plant age, drying process, and collection season.

CRISPR gene editing of major domestication traits accelerating breeding for Solanaceae crops improvement.

Domestication traits particularly fruit size and plant architecture and flowering are critical in transforming a progenitor's wild stature into a super improved plant. The latest advancements in the CRISPR system, as well as its rapid adoption, are speeding up plant breeding. Solanaceae has a varied range of important crops, with a few model crops, such as tomato and, more recently, groundcherry, serving as a foundation for developing molecular techniques, genome editing tools, and establishing standards for other crops.

Identification of fruit size associated quantitative trait loci featuring SLAF based high-density linkage map of goji berry (Lycium spp.).

Background: Goji (Lycium spp., 2n = 24) is a fruit bearing woody plant popular as a superfood for extensive medicinal and nutritional advantages. Fruit size associated attributes are important for evaluating small-fruited goji berry and plant architecture.

Isolation of Flavonoids From Wild Aquilaria sinensis Leaves by an Improved Preparative High-Speed Counter-Current Chromatography Apparatus.

Four flavonoids including apigenin-7,4'-dimethylether, genkwanin, quercetin, and kaempferol were isolated in a preparative or semi-preparative scale from the leaves of wild Aquilaria sinensis using an improved preparative high-speed counter-current chromatography apparatus. The separations were performed with a two-phase solvent system composed of hexane-ethyl acetate, methanol-water at suitable volume ratios. The obtained fractions were analyzed by HPLC, and the identification of each target compound was carried out by ESI-MS and NMR.
