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.

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.

Mapping of a Major QTL, , for Bakanae Disease Resistance in Rice.

Accelerated development of rice stripe virus-resistant, near-isogenic rice lines through marker-assisted backcrossing.

The development of new improved varieties is one of the major goals of plant breeding. Concomitantly, the demand for stable, eco-friendly, and high-quality rice production is constantly increasing. However, most farmers prefer to cultivate familiar rice varieties developed more than 10 years ago to minimize economic risk.

Fine mapping of qBK1, a major QTL for bakanae disease resistance in rice.

Background: Bakanae disease is an important fungal disease caused by Gibberella fujikuroi. Incidence of rice bakanae disease creates serious problems in the foremost rice growing countries, and no rice variety has been found to be completely resistant to this disease. However, breeding rice varieties resistant to bakanae disease may be a cost-saving solution preferable to the application of fungicides.
