Molecular Breeding of Porcine Circovirus Type 2 by Synthetic DNA Shuffling
Porcine circovirus type 2 (PCV2) is a small, non-enveloped, single-stranded DNA virus that causes disease in pigs and is an economically important pathogen affecting pig populations worldwide. PCV2 contains two major open reading frames (ORF): ORF1 encodes two replicase proteins and ORF2 encodes …

Development of Soybean Knowledge Base (SoyKB), a multi-omics data integration web resource for bridging molecular breeding and translational genomics in Glycine Max
… resource for soybean translational genomics and breeding. SoyKB handles the management and integration of soybean genomics and multi-omics data along with gene function annotations, biological pathway and trait information. It has many useful tools including Missouri Breeding Program, gene family …

REGULATING CYTOKININ METABOLISM DURING INFLORESCENCE MERISTEM DEVELOPMENT TO PROMOTE HIGHER RICE PRODUCTIVITY THROUGH CHANGES ON PLANT ARCHITECTURE
… determination and are potential targets for rice molecular breeding programs. Drought stress is one of the most damaging factors in agriculture due to the unpredictability of its occurrence, intensity, timing, and duration, as well as its interaction with other abiotic stresses. Since CKX genes …

Effect of Harvest Time on the Incidence of Red Drupelet Reversion and Development of Tetraploid Linkage Maps in Blackberry
… have been achieved without decades of diligent breeding efforts. Although the genetic improvement of fresh-market blackberries has advanced, there are still issues that need to be addressed. One issue is the prevalence of red drupelet reversion (RDR), a physiological disorder where the drupelets …

Simultaneous Mapping and Pyramiding of Fusarium Head Blight Resistance Loci in Wheat Breeding Populations
… between QTL mapping and marker-assisted breeding efforts aimed at pyramiding QTL, since no direct bridge exists between the populations within which these activities are conducted. Through this body of research, we demonstrate the application of linkage analysis directly in wheat breeding …

Quantitative trait loci (QTL) for metabolite accumulation and metabolic regulation : metabolite profiling of interspecific crosses of tomato
… of complex systems. Domestication and intensive breeding of crop plants has led to a parallel narrowing of their genetic basis. The potential to improve crops by conventional breeding using elite cultivars is therefore rather limited and molecular technologies, such as marker assisted selection …

Reverse Genetics-based Approaches to Attenuate Porcine Reproductive and Respiratory Syndrome Virus (PRRSV)
… clone of PRRSV, we successfully applied the molecular breeding approach to rapidly attenuate PRRSV. The GP5 envelope genes of 7 genetically divergent PRRSV strains and the GP5-M genes of 6 different PRRSV strains were molecularly bred. DS722 with shuffled GP5 genes and DS5M3 with shuffled …

Systems-Level Analysis of Rootstock–Scion Interactions in Apple Reveals Mechanisms of Cold Tolerance Under Field Frost Events
… for future efforts in rootstock improvement and molecular breeding. These findings offer promising targets for developing cold-tolerant apple germplasm and improving orchard management, while more broadly providing a framework to understand how rootstock–scion interactions modulate complex …

Genomic Selection, Quantitative Trait Loci and Genome-Wide Association Mapping for Spring Bread Wheat (Triticum aestivum L.) Improvement
Molecular breeding involves the use of molecular markers to identify and characterize genes that control quantitative traits. Two of the most commonly used methods to dissect complex traits in plants are linkage analysis and association mapping. These methods are used to identify markers associated …

Flavour quality factors and its regulation in red raspberry (rubus idaeus)
Breeding in red raspberries is hampered by genetic incompatibility between varieties and a long juvenility period. Molecular breeding efforts in red raspberry have provided viable applications to incorporate disease resistance in new varieties. This approach could also be applied in developing …
