Artificial Rainfall on Grain Quality and Baking Characteristics of Winter Wheat Cultivars in Korea.

Wheat ( L.) stands as a significant cereal crop globally, including in Korea, where its consumption reached 35.7 kg per capita in 2023.

Synergizing breeding strategies via combining speed breeding, phenotypic selection, and marker-assisted backcrossing for the introgression of in wheat.

Wheat is a major food crop that plays a crucial role in the human diet. Various breeding technologies have been developed and refined to meet the increasing global wheat demand. Several studies have suggested breeding strategies that combine generation acceleration systems and molecular breeding methods to maximize breeding efficiency.

Acceleration of wheat breeding: enhancing efficiency and practical application of the speed breeding system.

Background: Crop breeding should be accelerated to address global warming and climate change. Wheat (Triticum aestivum L.) is a major food crop.

Multiple Facets of Nitrogen: From Atmospheric Gas to Indispensable Agricultural Input.

Nitrogen (N) is a gas and the fifth most abundant element naturally found in the atmosphere. N's role in agriculture and plant metabolism has been widely investigated for decades, and extensive information regarding this subject is available. However, the advent of sequencing technology and the advances in plant biotechnology, coupled with the growing interest in functional genomics-related studies and the various environmental challenges, have paved novel paths to rediscovering the fundamentals of N and its dynamics in physiological and biological processes, as well as biochemical reactions under both normal and stress conditions.

Speed vernalization to accelerate generation advance in winter cereal crops.

There are many challenges facing the development of high-yielding, nutritious crops for future environments. One limiting factor is generation time, which prolongs research and plant breeding timelines. Recent advances in speed breeding protocols have dramatically reduced generation time for many short-day and long-day species by optimizing light and temperature conditions during plant growth.

Novel QTL Associated with Aerenchyma-Mediated Radial Oxygen Loss (ROL) in Rice ( L.) under Iron (II) Sulfide.

In rice, high radial oxygen loss (ROL) has been associated with the reduction in the activity of methanogens, therefore reducing the formation of methane (CH) due to the abundance in application of nitrogen (N)-rich fertilizers. In this study, we evaluated the root growth behavior and ROL rate of a doubled haploid (DH) population ( = 117) and parental lines 93-11 (P1, ) and Milyang352 (P2, ) in response to iron (II) sulfide (FeS). In addition, we performed a linkage mapping and quantitative trait locus (QTL) analysis on the same population for the target traits.

RNA-Seq and Electrical Penetration Graph Revealed the Role of -Mediated Activation of Defense Mechanisms towards Green Rice Leafhopper ( Uhler) Resistance in Rice ( L.).

The green rice leafhopper (GRH, Uhler) is one of the most important insect pests causing serious damage to rice production and yield loss in East Asia. Prior to performing RNA-Seq analysis, we conducted an electrical penetration graph (EPG) test to investigate the feeding behavior of GRH on Ilpum (recurrent parent, GRH-susceptible cultivar), a near-isogenic line (NIL carrying ) compared to the donor parent (Shingwang). Then, we conducted a transcriptome-wide analysis of GRH-responsive genes in Ilpum and NIL, which was followed by the validation of RNA-Seq data by qPCR.

Novel QTL Associated with Shoot Branching Identified in Doubled Haploid Rice ( L.) under Low Nitrogen Cultivation.

Shoot branching is considered as an important trait for the architecture of plants and contributes to their growth and productivity. In cereal crops, such as rice, shoot branching is controlled by many factors, including phytohormones signaling networks, operating either in synergy or antagonizing each other. In rice, shoot branching indicates the ability to produce more tillers that are essential for achieving high productivity and yield potential.

New Insights into the Transcriptional Regulation of Genes Involved in the Nitrogen Use Efficiency under Potassium Chlorate in Rice ( L.).

Potassium chlorate (KClO) has been widely used to evaluate the divergence in nitrogen use efficiency (NUE) between and rice subspecies. This study investigated the transcriptional regulation of major genes involved in the NUE in rice treated with KClO, which acts as an inhibitor of the reducing activity of nitrate reductase (NR) in higher plants. A set of two KClO sensitive nitrate reductase (NR) and two nitrate transporter (NRT) introgression rice lines (BC2F7), carrying the alleles of NR or NRT, derived from a cross between Saeilmi (, P1) and Milyang23 (, P2), were exposed to KClO at the seedling stage.

Rapid and Easy High-Molecular-Weight Glutenin Subunit Identification System by Lab-on-a-Chip in Wheat ( L.).

Lab-on-a-chip technology is an emerging and convenient system to easily and quickly separate proteins of high molecular weight. The current study established a high-molecular-weight glutenin subunit (HMW-GS) identification system using Lab-on-a-chip for three, six, and three of the allelic variations at the , , and loci, respectively, which are commonly used in wheat breeding programs. The molecular weight of 1Ax1 and 1Ax2* encoded by locus were of 200 kDa and 192 kDa and positioned below 1Dx subunits.
