“…Marker-assisted breeding (MAB) is the most promising of the many applications of DNA markers in plant science for cultivar creation. MAB has huge potential to increase conventional plant breeding efficiency and precision by using DNA markers that are firmly related to critical genes or loci [33]. Several allele-specific functional markers for essential soybean features such as blooming and maturity, pod dehiscence, aroma, salt tolerance, soybean cyst nematode oleic acid content, raffinose content, and Kunitz trypsin inhibitor have recently been discovered [33,34].…”

Soybean is a globally important crop being rich source of edible oil and protein. Traditional phenotypic-based breeding procedures have contributed significantly to the development of several improved soybean varieties. In this context, molecular breeding technology, is seen as a viable way to address the issues and providing great opportunities to accelerate the process of soybean breeding. Hence, marker-assisted breeding (MAB) has been greatly applied in the soybean breeding to accelerate the improved soybean cultivars, transgenic breeding technology achieves great success in the soybean production. New genomics approaches and the development of genome editing technologies have increased soybean genetic diversity in its germplasm and have created new possibility to make precise genes modifications to controlling essential agronomic traits in an elite background Besides, the establishment of genotype driven phenotypic design breeding model has become a great challenge for soybean molecular breeding in the future. These approaches have the potential to expand the practical utility of molecular design breeding and speed up the germplasm and breeding materials in soybeans. This chapter goes into great detail about how current advances in genomics and phenomics can increase the efficiency and potential of MAB, transgenic technology, molecular design breeding and gene editing technology in soybean improvement.

Biotic stress is a critical factor limiting soybean growth and development. Soybean responses to biotic stresses such as insects, nematodes, and fungal, bacterial, and viral pathogens are governed by complex regulatory and defense mechanisms. Next-generation sequencing has availed research techniques and strategies in genomics and post-genomics. This review summarizes the available information on marker resources, quantitative trait loci, and marker trait associations involved in regulating biotic stress responses of soybean. We discuss the differential expression of related genes and proteins reported in different transcriptomics and proteomics studies and the role of signaling pathways and metabolites reported in metabolomic studies. Recent advances in omics technologies offer opportunities to reshape and improve biotic stress resistance in soybean by altering gene regulation and/or other regulatory networks. We recommend using ‘integrated omics’ to understand how soybean responds to different biotic stresses. We discuss the potential challenges of integrating multi-omics for functional analysis of genes and their regulatory networks and the development of biotic stress-resistant cultivars. This review will help direct soybean breeding programs to develop resistance against different biotic stresses.

Background Drought stress limits the production of soybean [Glycine max (L.) Merr.], which is the most grown high-value legume crop worldwide. Breeding for drought tolerance is a difficult endeavor and understanding the genetic basis of drought tolerance in soybean is therefore crucial for harnessing the genomic regions involved in the tolerance mechanisms. A genome-wide association study (GWAS) analysis was applied in a soybean germplasm collection (the EUCLEG collection) of 359 accessions relevant for breeding in Europe, to identify genomic regions and candidate genes involved in the response to short duration and long duration drought stress (SDS and LDS respectively) in soybean. Results The phenotypic response to drought was stronger in the long duration drought (LDS) than in the short duration drought (SDS) experiment. Over the four traits considered (canopy wilting, leaf senescence, maximum absolute growth rate and maximum plant height) the variation was in the range of 8.4−25.2% in the SDS, and 14.7−29.7% in the LDS experiments. The GWAS analysis identified a total of 17 and 22 significant marker-trait associations for four traits in the SDS and LDS experiments, respectively. In the genomic regions delimited by these markers we identified a total of 12 and 16 genes with putative functions that are of particular relevance for drought stress responses including stomatal movement, root formation, photosynthesis, ABA signaling, cellular protection and cellular repair mechanisms. Some of these genomic regions co-localized with previously known QTLs for drought tolerance traits including water use efficiency, chlorophyll content and photosynthesis. Conclusion Our results indicate that the mechanism of slow wilting in the SDS might be associated with the characteristics of the root system, whereas in the LDS, slow wilting could be due to low stomatal conductance and transpiration rates enabling a high WUE. Drought-induced leaf senescence was found to be associated to ABA and ROS responses. The QTLs related to WUE contributed to growth rate and canopy height maintenance under drought stress. Co-localization of several previously known QTLs for multiple agronomic traits with the SNPs identified in this study, highlights the importance of the identified genomic regions for the improvement of agronomic performance in addition to drought tolerance in the EUCLEG collection.
