The identification of presence/absence variants associated with the apparent differences of growth period structures between cultivated and wild soybeans
Published 2016-02-01Get full textAbstract: The cultivated soybean (Glycine max (L.) Merr.) was distinguished from its wild progenitor Glycine soja Sieb. & Zucc. in growth period structure, by a shorter vegetative phase (V), a prolonged reproductive phase (R) and hence a larger R/V ratio. However, the genetic basis of the do...

Development and identification of glyphosate-tolerant transgenic soybean via direct selection with glyphosate
Published 2020-05-01Get full textGlyphosate-tolerant soybean is the most widely planted genetically modified crop worldwide. However, soybean remains recalcitrant to routine transformation because of the low infection efficiency of Agrobacterium to soybean and lack of useful selectable markers. In this study, several Agrobacterium...

Identification and characterization of long-InDels through whole genome resequencing to facilitate fine-mapping of a QTL for plant height in soybean (Glycine max L. Merr.)
Published 2022-07-01Get full textWith the development of sequencing technology, insertions-deletions (InDels) have been increasingly reported to be involved in the genetic determination of agronomical traits. However, most studies have focused on the identification and application of short-InDels (1–15 bp) for genetic analysis. The...

Identification of the genetic locus associated with the crinkled leaf phenotype in a soybean (Glycine max L.) mutant by BSA-Seq technology
Published 2022-12-01Get full textThe leaf is the main photosynthetic organ of plants, and it plays a significant role in the yield of crop species. Identifying the causal mutations and candidate genes that underlie leaf phenotypic variation is an important breeding target in soybean grain yield improvement. An ethyl methyl sulfonat...

Co-treatment with surfactant and sonication significantly improves Agrobacterium-mediated resistant bud formation and transient expression efficiency in soybean
Published 2015-07-01Get full textSoybean is a widely planted genetically modified crop around the world. However, it is still one of the most recalcitrant crops for genetic transformation due to the difficulty of regeneration via organogenesis and some factors that affect the transformation efficiency. The percentages of resistant...

Pseudomonas sp. TK35-L enhances tobacco root development and growth by inducing HRGPnt3 expression in plant lateral root formation
Published 2020-10-01Get full textRhizosphere colonization is a key requirement for the application of plant growth-promoting rhizobacteria (PGPR) as a biofertilizer. Signaling molecules are often exchanged between PGPR and plants, and genes in plants may respond to the action of PGPR. Here, the luciferase luxAB gene was electrotran...

A Dominant Locus, qBSC-1, Controls β Subunit Content of Seed Storage Protein in Soybean (Glycine max (L.) Merri.)
Published 2014-09-01Get full textSoybean seed storage protein is one of the most important plant vegetable proteins, and β subunit is of great significance to enhance soybean protein quality and processing property. F2 segregated population and residual heterozygous lines (RHL) derived from the cross between Yangyandou (low level o...

QTL analysis for plant height and fine mapping of two environmentally stable QTLs with major effects in soybean
Published 2022-04-01Get full textPlant height is an important agronomic trait, which is governed by multiple genes with major or minor effects. Of numerous QTLs for plant height reported in soybean, most are in large genomic regions, which results in a still unknown molecular mechanism for plant height. Increasing the density of mo...

Establishment and application of an accurate identification method for fragrant soybeans
Published 2021-05-01Get full textIn order to screen the aroma characteristics of soybean, a new method was established which can quickly quantify the content of 2-acetyl-1pyrroline (2-AP), an important compound related to soybean aroma, using gas chromatography-mass spectrometry (GC-MS). Based on peak profile, total peak area and r...

Characterization of the petiole length in soybean compact architecture mutant M657 and the breeding of new lines
Published 2022-01-01Get full textPhenotypic screening of soybean germplasm suitable for high planting density is currently the most viable strategy to increase yield. Previous studies have shown that soybean varieties with dwarf features and a short petiole often exhibit a compact plant architecture which could improve yield throug...

Identification of tolerance to high density and lodging in short petiolate germplasm M657 and the effect of density on yield-related phenotypes of soybean
Published 2023-02-01Get full textSoybean yield has traditionally been increased through high planting density, but investigating plant height and petiole traits to select for compact architecture, lodging resistance, and high yield varieties is an underexplored option for further improving yield. We compared the relationships betwe...

Stability of growth periods traits for soybean cultivars across multiple locations
Published 2016-05-01Get full textThe growth periods (GPs, from planting/emergence to reproductive stage 8 (R8) of soybean cultivars vary in different ecological regions, especially in China with a very complex soybean cropping system. In this study, a 3-yr experimental study was undertaken in three geographical locations of China f...

Genetic diversity center of cultivated soybean (Glycine max) in China – New insight and evidence for the diversity center of Chinese cultivated soybean
Published 2016-11-01Get full textInformation on the center of genetic diversity of soybean (Glycine max) will be helpful not only for designing efficient strategies for breeding programs, but also for understanding the domestication and origin of this species. Here, we describe an analysis of genetic diversity based on simple-seque...
