Special Issue Information

Dear Colleagues,

Genome-editing technology enables breeders to precisely adjust traits of interest with unprecedented control and efficiency for the first time. The emergence of genome editing has aroused people's enthusiasm, but also triggered controversy, bringing challenges to global regulation and governance. Plant genome editing plays a key role in gene function research, crop genetic improvement, yield improvement, disease and pest control, molecular precision breeding, etc. It will make a significant contribution to achieving a variety of sustainable development goals. With the rapid progress of science, policy and management methods have become increasingly important. At present, some countries have made legislative adjustments to these technologies or issued guidelines to support the use of genome editing. Other countries have also discussed the future path of this, but the legal classification is not clear or the consensus is hindered due to the debate on transgenic plants.

This research topic aims to collect articles on the latest progress and future goals of genome editing, as well as contributions to regulatory, social and socio-economic aspects, ethics, risk assessment, management and biosafety research. We will focus on how to define the legal status of genome-editing products and how to carry out international policy coordination. Authors are particularly invited to discuss one or more of the following aspects:

1) Background—Plant genome editing:

  • Existing technologies and applications;
  • Future expectation of genome editing;
  • How to address global challenges.

2) Supervision, assessment, safety:

  • Summary of current biosafety regulations;
  • How to detect/execute;
  • Alternative regulatory approaches;
  • Does the established risk assessment strategy fit the purpose?
  • Methods for assessing non-targeted changes in the genome;
  • Triggers to guide appropriate and proportionate risk assessments.

3) Social, economic, morality and ethics:

  • How to responsibly develop and use genome editing: concepts, challenges and examples;
  • Cognition, such as similarities and differences between GM foods and genome-editing foods;
  • Possible social and socio-economic impacts of different regulatory scenarios;
  • Genome editing as a turning point in the ethical debate on plant genetic modification;
  • Ethical reasonableness of the precautionary principle on genome-editing risk issues.

Understanding the mechanisms of responses to high temperatures in Arabidopsis will provide insights into how plants may mitigate heat stress under global climate change. And exploring the interconnections of different modification levels in heat stress response could help us to understand the molecular mechanism of heat stress response in Arabidopsis more comprehensively and precisely. In this paper, we combined multiomics analyses to explore the common heat stress-responsive genes and specific heat-responsive metabolic pathways in Arabidopsis leaf, seedling, and seed tissues. We found that genes such as AT1G54050 play a role in promoting proper protein folding in response to HS (Heat stress). In addition, it was revealed that the binding profile of A1B is altered under elevated temperature conditions. Finally, we also show that two microRNAs, ath-mir156h and ath-mir166b-5p, may be core regulatory molecules in HS. Also elucidated that under HS, plants can regulate specific regulatory mechanisms, such as oxygen levels, by altering the degree of CHH methylation. Full article

OsNPR1 Enhances Rice Resistance to Xanthomonas oryzae pv. oryzae by Upregulating Rice Defense Genes and Repressing Bacteria Virulence Genes

The bacteria pathogen Xanthomonas oryzae pv. oryzae (Xoo) infects rice and causes the severe disease of rice bacteria blight. As the central regulator of the salic acid (SA) signaling pathway, NPR1 is responsible for sensing SA and inducing the expression of pathogen-related (PR) genes in plants. Overexpression of OsNPR1 significantly increases rice resistance to Xoo. Although some downstream rice genes were found to be regulated by OsNPR1, how OsNPR1 affects the interaction of rice-Xoo and alters Xoo gene expression remains unknown. In this study, we challenged the wild-type and OsNPR1-OE rice materials with Xoo and performed dual RNA-seq analyses for the rice and Xoo genomes simultaneously. In Xoo-infected OsNPR1-OE plants, rice genes involved in cell wall biosynthesis and SA signaling pathways, as well as PR genes and nucleotide-binding site-leucine-rich repeat (NBS-LRR) genes, were significantly upregulated compared to rice variety TP309. On the other hand, Xoo genes involved in energy metabolism, oxidative phosphorylation, biosynthesis of primary and secondary metabolism, and transportation were repressed. Many virulence genes of Xoo, including genes encoding components of type III and other secretion systems, were downregulated by OsNPR1 overexpression. Our results suggest that OsNPR1 enhances rice resistance to Xoo by bidirectionally regulating gene expression in rice and Xoo. Full article
