Special Issue Information

Dear Colleagues,

Scientists are able to edit genomes efficiently and cost-effectively thanks to the many high-quality reference genome sequences that are currently available. Zinc finger nucleases (ZFNs), transcription activator-like effector-based nucleases (TALENs), and the clustered regularly interspaced short palindromic repeats (CRISPR)-Cas system have successfully been employed to edit numerous individual genes in many organisms, and CRISPR-edited plants are now on the market. The CRISPR-Cas system has been widely used to edit genetic elements in genomes for various applications—not only crop improvement but also many gene therapy studies. For this Special Issue, we cordially invite scientists from around the world to contribute their cutting-edge research on plant genomics and genome editing. We welcome the submission of original research articles and short communications contributing to the advancement of genomics and genome editing, including techniques, applications, trait development, and enabling database as well as computational software. We are also inviting scientists to write reviews for this Special Issue.

Dr. Fabrizio Carbone
Guest Editor

PCR methods are widely applied for the detection of genetically modified organisms (GMOs) in Europe, facilitating compliance with stringent regulatory requirements and enabling the accurate identification and quantification of genetically modified traits in various crops and foodstuffs. This manuscript investigates the suitability of real-time PCR methods for detecting organisms generated through new genomic techniques (NGTs), specifically focusing on a case study using Arabidopsis thaliana as a model gene-edited plant. Given the complexities of European regulations regarding genetically modified organisms (GMOs) and the classification of gene-edited plants, there is a pressing need for robust detection methods. Our study highlights the development and validation of a novel single-plex real-time PCR method targeting a specific single nucleotide polymorphism (SNP) in the grf1-3 gene modified using CRISPR-Cas9 technology. We emphasize the effectiveness of locked nucleic acid (LNA)-modified primers in improving specificity. The results demonstrate that while the grf1-3 LNA method successfully detected and quantified gene-edited Arabidopsis DNA, achieving absolute specificity remains a challenge. This study also addresses the significance of the cross-laboratory method for validation, demonstrating that the method developed for an SNP-modified allele can be performed in accordance with the precision and trueness criteria established by the European Network of GMO Laboratories (ENGL). Furthermore, we call for continued collaboration among regulatory agencies, academia, and industry stakeholders to refine detection strategies. This proactive approach is essential not only for regulatory compliance but also for maintaining public trust in the safe integration of gene-edited organisms into food products. Full article

Soil salinity is one of the most severe impacts of climate change, negatively affecting plant growth and development. Seed germination and seedling emergence are among the most critical stages susceptible to salt stress, making it important to explore them to identify the most resilient accessions for crop yield improvement. Cowpea (Vigna unguiculata L. Walp.) is an important crop due to its ability to fix atmospheric nitrogen, improving soil health, and its high protein content. The main objectives of this study were to screen salt-resilient cowpea accessions from a worldwide collection and to evaluate cowpea responses to salt stress at germination stage through gene expression analysis. A total of 40 cowpea accessions from sixteen different countries were subjected to two treatments: control (water) and salt stress (150 mM NaCl solution). The seeds germinated, and the seedlings grew for ten days. The germination and growth parameters and lipid peroxidation quantification were determined. The results revealed significant differences in all parameters among accessions and treatments. A high variation in salt responses was detected among accessions, allowing the selection of five accessions (Co_2, Co_4, Co_21, Co_30, Co_31) as resilient to salt stress at germination stage. Subsequently, two salt stress-related genes (DREB2 and VuEXO) were evaluated through qPCR, revealing genotype-dependent regulation. These results provide valuable insights for the early selection of salt-resilient cowpea accessions, which may be considered for the development of improved and new varieties in the future.
