Genotyping-by-Sequencing Analysis Reveals Associations between Agronomic and Oil Traits in Gamma Ray-Derived Mutant Rapeseed ( L.).

Rapeseed ( L.) holds significant commercial value as one of the leading oil crops, with its agronomic features and oil quality being crucial determinants. In this investigation, 73,226 single nucleotide polymorphisms (SNPs) across 95 rapeseed mutant lines induced by gamma rays, alongside the original cultivar ('Tamra'), using genotyping-by-sequencing (GBS) analysis were examined.

Identification of Loci Governing Agronomic Traits and Mutation Hotspots via a GBS-Based Genome-Wide Association Study in a Soybean Mutant Diversity Pool.

In this study, we performed a genotyping-by-sequencing analysis and a genome-wide association study of a soybean mutant diversity pool previously constructed by gamma irradiation. A GWAS was conducted to detect significant associations between 37,249 SNPs, 11 agronomic traits, and 6 phytochemical traits. In the merged data set, 66 SNPs on 13 chromosomes were highly associated (FDR p < 0.

Stimuli-Responsive Drug Delivery of Doxorubicin Using Magnetic Nanoparticle Conjugated Poly(ethylene glycol)--Chitosan Copolymer.

Stimuli-responsive nanoparticles are regarded as an ideal candidate for anticancer drug targeting. We synthesized glutathione (GSH) and magnetic-sensitive nanocomposites for a dual-targeting strategy. To achieve this goal, methoxy poly (ethylene glycol) (MePEG) was grafted to water-soluble chitosan (abbreviated as ChitoPEG).

Differential Gene Expression Associated with Altered Isoflavone and Fatty Acid Contents in Soybean Mutant Diversity Pool.

Soybean seeds are consumed worldwide owing to their nutritional value and health benefits. In this study we investigated the metabolic properties of 208 soybean mutant diversity pool (MDP) lines by measuring the isoflavone and fatty acid contents of the seed. The total isoflavone content (TIC) ranged from 0.

Development of vitrification protocol in Rubia akane (nakai) hairy roots using a systematic approach.

Background: A solution-based vitrification protocol is a process of sequentially changing-solutions from which both influx of cryoprotectants (loading) and efflux of water (dehydration) were accomplished before cryo-exposure. Hence, we need to properly control the concentration /composition of the cryoprotectant solutions.

Objective: The study was, using a systematic approach, to develop a protocol for Rubia akane hairy roots, a very sensitive material to cytotoxicity of vitrification solutions.

Improved cryopreservation of chrysanthemum (Chrysanthemum morifolium) using droplet-vitrification.

A droplet-vitrification protocol has been established for cryopreserving Chrysanthemum morifolium cv. Peak using axillary shoot tips and apical shoots of in vitro plants. In the optimized procedure, explants were submitted to a step-wise preculture in liquid sucrose-enriched medium (0.

Production of herbicide-tolerant zoysiagrass by Agrobacterium-mediated transformation.

Herbicide-resistant zoysiagrass (Zoysia japonica Steud.) has been developed by Agrobacterium-mediated transformation. A callus-type transformation system was established by optimizing several factors that affect the rate of transformation, including co-cultivation period and concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D), CaCl2 and acetosyringone.
