Special Issue Information

Dear Colleagues,

Strategic crops, also known as staple crops, play a crucial role in providing essential nutrients and sustenance for both human consumption and animal feed. In light of the exponential growth in the global population, there is a concurrent surge in the demand for strategic crops such as wheat, rice, maize, and soybean, thereby underlining the significance of enhancing crop production with a focus on enhancing yield, nutritional content, and sustainability. Consequently, there has been a pronounced escalation in research endeavors aimed at deciphering the intricate molecular mechanisms governing complex traits, as well as advancing biotechnological methodologies to bolster crop cultivation and production.

Substantial progress has recently been achieved in the realm of molecular-based crop breeding, driven by significant strides in functional genomics tools and the accessibility of high-throughput sequencing technologies. These advancements have empowered plant scientists to precisely unravel the genetic foundations underpinning key traits, including yield, disease resistance, and seed composition, in different crops. Furthermore, the synergistic integration of omics methodologies, such as genomics, transcriptomics, proteomics, and metabolomics, has led to a profound comprehension of the complicated molecular mechanisms governing crop growth, development, and its complex responses to diverse biotic and abiotic stresses.

Crop molecular-based breeding research, including genomic selection approaches, marker-assisted selections, and genome editing techniques, has not only enabled breeders to successfully develop cultivars with improved agronomic performance but also improved our understanding of crop biology, which leads to sustainable production practices.

In this Special Issue, we aim to spotlight the latest advancements in molecular research pertaining to strategic crops and their practical applications aimed at enhancing crop production. This Special Issue will encompass a wide array of subjects, comprising, but not limited to:

  1. Genome-wide association studies (GWASs) and quantitative trait loci (QTL) mapping for important traits such as yield, disease resistance, and seed composition.
  2. Applications of transcriptional profiling and functional genomics tools in deciphering the molecular mechanisms underlying key traits.
  3. The role of omics approaches in understanding the genetic basis of abiotic and biotic stress responses, including drought, heat, and pathogen infections.
  4. Biotechnological approaches for improving productivity, such as marker-assisted selection and genome editing.
  5. Nutritional genomics and the development of varieties with enhanced nutritional properties, including proteins, fatty acids, and micronutrients.
  6. Data-driven approaches to increase the speed and accuracy of molecular breeding.

We invite the submission of original research articles, comprehensive reviews, and insightful perspectives encompassing both fundamental and practical facets of molecular-based investigations in the realm of strategic crops. This Special Issue endeavors to offer a comprehensive snapshot of the present landscape of molecular research in strategic crops, emphasizing recent breakthroughs and delineating the potential trajectories for future research endeavors in this field.

Sincerely,

Soybean cyst nematode (SCN, Heterodera glycines, Ichinohe) poses a significant threat to global soybean production, necessitating a comprehensive understanding of soybean plants’ response to SCN to ensure effective management practices. In this study, we conducted dual RNA-seq analysis on SCN-resistant Plant Introduction (PI) 437654, 548402, and 88788 as well as a susceptible line (Lee 74) under exposure to SCN HG type 1.2.5.7. We aimed to elucidate resistant mechanisms in soybean and identify SCN virulence genes contributing to resistance breakdown. Transcriptomic and pathway analyses identified the phenylpropanoid, MAPK signaling, plant hormone signal transduction, and secondary metabolite pathways as key players in resistance mechanisms. Notably, PI 437654 exhibited complete resistance and displayed distinctive gene expression related to cell wall strengthening, oxidative enzymes, ROS scavengers, and Ca2+ sensors governing salicylic acid biosynthesis. Additionally, host studies with varying immunity levels and a susceptible line shed light on SCN pathogenesis and its modulation of virulence genes to evade host immunity. These novel findings provide insights into the molecular mechanisms underlying soybean–SCN interactions and offer potential targets for nematode disease management. Full article
