Molecular characterization of QTL for grain zinc and iron concentrations in wheat landrace Chinese Spring.

Three stable QTL for grain zinc concentration were identified in wheat landrace Chinese Spring. Favorable alleles were more frequent in landraces than in modern wheat cultivars. Wheat is a major source of dietary energy for the growing world population.

Identification of hub genes regulating isoflavone accumulation in soybean seeds GWAS and WGCNA approaches.

Introduction: Isoflavones are the secondary metabolites synthesized by the phenylpropanoid biosynthesis pathway in soybean that benefits human and plant health.

Methods: In this study, we have profiled seed isoflavone content by HPLC in 1551 soybean accessions grown in Beijing and Hainan for two consecutive years (2017 and 2018) and in Anhui for one year (2017).

Results: A broad range of phenotypic variations was observed for individual and total isoflavone (TIF) content.

Characterization and Transcriptome Analysis of Maize Small-Kernel Mutant in Different Development Stages.

The kernel serves as a storage organ for various nutrients and determines the yield and quality of maize. Understanding the mechanisms regulating kernel development is important for maize production. In this study, a small-kernel mutant of maize was characterized.

Identification of genes for seed isoflavones based on bulk segregant analysis sequencing in soybean natural population.

We identified four hub genes for isoflavone biosynthesis based on BSA-seq and WGCNA methods and validated that GmIE3-1 positively contribute to isoflavone accumulation in soybean. Soybean isoflavones are secondary metabolites of great interest owing to their beneficial impact on human health. Herein, we profiled the seed isoflavone content by HPLC in 1551 soybean accessions grown in two locations for two years and constructed two extreme pools with high (4065.

Characterization of salt tolerant wheat genotypes by using morpho-physiological, biochemical, and molecular analysis.

Food security is facing a major threat from salinity and there is a need to develop salt tolerant crop varieties to ensure that the demand for food from the world's increasing population is met. Salinity mostly occurs in arid and semi-arid regions. It may cause many adverse physiological effects on plants, i.

Identification of Genomic Loci and Candidate Genes Related to Seed Tocopherol Content in Soybean.

Soybean seeds are primary sources of natural tocopherols used by the food and pharmaceutical industries, owing to their beneficial impacts on human health. Selection for higher tocopherol contents in seeds along with other desirable traits is an important goal in soybean breeding. In order to identify the genomic loci and candidate genes controlling tocopherol content in soybean seeds, the bulked-segregant analysis technique was performed using a natural population of soybean consisting of 1525 accessions.

Identification of effective alleles and haplotypes conferring pre-harvest sprouting resistance in winter wheat cultivars.

Background: Pre-harvest sprouting (PHS) is a serious limiting factor for wheat (Triticum aestivum L.) grain yield and end-use quality. Identification of reliable molecular markers and PHS-resistant germplasms is vital to improve PHS resistance by molecular marker-assisted selection (MAS), but the effects of allelic variation and haplotypes in genes conferring PHS resistance in winter wheat cultivars are less understood.

Association of the Recessive Allele With Winter Frost Tolerance in Bread Wheat.

Winter frost has been considered the primary limiting factor in wheat production. Shimai 12 is an elite wheat cultivar grown in central and southern Hebei province of China, but sensitive to winter frost. In this study, the winter frost tolerant cultivar Lunxuan 103 was bred by introducing the recessive allele from winter wheat Shijiazhuang 8 (frost tolerance) into Shimai 12 using marker-assisted selection (MAS).

New Insights into Evolution of the ABC Transporter Family in , a Unicellular Charophyte Algae.

ATP-binding cassette (ABC) transporters play an important role in driving the exchange of multiple molecules across cell membranes. The plant ABC transporter family is among the largest protein families, and recent progress has advanced our understanding of ABC classification. However, the ancestral form and deep origin of plant ABCs remain elusive.

Identification of a Allele as a Powdery Mildew Resistance Gene in Wheat Line Xiaomaomai.

Powdery mildew, caused by f. sp. (), is one of the most destructive foliar diseases of wheat.
