Introduction

CRISPR/Cas9 technology is revolutionizing plant pathogen resistance by enabling precise genetic alterations [1].

This approach involves targeting host susceptibility genes or pathogen virulence factors, showing immense potential for sustainable agriculture. Reviews highlight its mechanisms and successful applications in various crops, alongside the remaining hurdles for widespread adoption. The advancement of CRISPR-Cas systems is crucial for developing disease-resistant crops through precision breeding [2].

These precise tools facilitate targeted modifications to plant genomes, enhancing their natural defenses against a broad spectrum of pathogens. This offers a sustainable and efficient alternative to traditional breeding methods, critical for modern agriculture. Genome editing technologies are particularly effective in enhancing plant resistance against fungal pathogens, which cause significant crop losses [3].

Strategies explored include modifying host susceptibility genes and engineering novel resistance mechanisms. This provides a robust path towards cultivating more resilient crops that can naturally defend against destructive fungal infections. CRISPR/Cas systems are also proving vital for engineering resistance against bacterial pathogens in agricultural crops [4].

This includes strategies such as knocking out susceptibility genes or introducing novel resistance genes. These targeted interventions demonstrate significant potential to safeguard staple crops from devastating bacterial infections that are often hard to control. Progress in genome editing also extends to conferring resistance against plant viruses, a major threat to global food security [5].

Various gene-editing approaches are outlined, such as targeting host factors essential for viral replication or introducing viral resistance genes. This field continually discusses both breakthroughs and ongoing challenges in deployment. A comprehensive overview details how CRISPR-Cas technology is creating disease-resistant crops [6].

It covers diverse strategies, from targeting host susceptibility genes to engineering broad-spectrum resistance. The review also critically discusses the complex regulatory landscape and essential public acceptance challenges for these biotechnological advancements. Innovative strategies aim to engineer broad-spectrum disease resistance by enhancing plants' innate immune systems [7].

Genetic modification of key immune components and signaling pathways provides more durable protection against diverse pathogens. This ultimately reduces reliance on chemical treatments, favoring natural, long-term plant defenses. CRISPR/Cas-based gene editing presents both significant opportunities and challenges for disease resistance in plants [8].

Precise genetic alterations can powerfully enhance natural defenses, offering a tool for sustainable disease management. However, navigating regulatory and technical hurdles is essential for widespread and responsible deployment. A focused strategy involves targeting plant susceptibility (S) genes with CRISPR-Cas9 to achieve robust disease resistance [9].

Knocking out or modifying these genes prevents pathogen colonization and infection. This provides a durable and broad-spectrum resistance mechanism against various agricultural pathogens, disrupting their ability to exploit host weaknesses. Ultimately, genome editing technologies contribute significantly to enhancing overall plant resilience, including disease resistance, in the face of climate change and emerging pathogens [10].

This involves scientific breakthroughs as well as essential regulatory and ethical considerations, all crucial for realizing the full potential of these tools in sustainable agriculture.

Genome editing technologies, particularly CRISPR-Cas systems, represent a profound shift in developing disease-resistant crops and enhancing overall plant resilience [1, 2, 6, 8, 10]. These precise tools enable targeted modifications to plant genomes, bolstering natural defenses against a broad spectrum of pathogens. This approach offers a sustainable and efficient alternative to traditional breeding methods, which often involve lengthy processes and less precise outcomes. The revolution in plant pathogen resistance stems from the ability to precisely target host susceptibility genes or pathogen virulence factors, underscoring its immense potential for sustainable agriculture [1]. What this really means is a move towards intrinsic plant immunity. The widespread application of CRISPR/Cas-based gene editing presents both significant opportunities and challenges for disease resistance in plants [8]. These precise genetic alterations can profoundly enhance natural defenses, positioning it as a powerful tool for sustainable disease management. It is crucial for maintaining global food security, especially considering the escalating global issues like climate change and the emergence of new pathogens [10]. This comprehensive view is vital for future development.

A key strategy within genome editing involves targeting plant susceptibility (S) genes with CRISPR-Cas9 to achieve robust disease resistance [9]. By knocking out or precisely modifying these genes, the technology effectively prevents pathogen colonization and subsequent infection. This method provides a durable and broad-spectrum resistance mechanism against various agricultural pathogens, disrupting their ability to exploit host weaknesses. Beyond this, CRISPR/Cas systems are strategically employed to engineer resistance against specific pathogen types. For instance, resistance against bacterial pathogens in agricultural crops is developed by strategies such as knocking out susceptibility genes or introducing novel resistance genes [4]. This demonstrates the potential to safeguard staple crops from devastating bacterial infections, which have historically been challenging to control. Similarly, significant effort is dedicated to enhancing plant resistance against fungal pathogens, major culprits for considerable crop losses [3]. This research delves into various innovative strategies, including the modification of host susceptibility genes and engineering novel resistance mechanisms, paving a clear path towards more resilient crops.

Progress in genome editing also extends to conferring robust resistance against plant viruses, a constant and evolving threat to global food security [5]. This involves outlining diverse gene-editing approaches, such as strategically targeting host factors essential for viral replication or introducing specific viral resistance genes. Discussions surrounding these innovations encompass both the significant scientific breakthroughs achieved and the persistent ongoing challenges that must be overcome for widespread, practical application. Furthermore, innovative strategies focus on engineering broad-spectrum disease resistance in plants by fundamentally enhancing their innate immune systems [7]. This research explores the genetic modification of key immune components and crucial signaling pathways. The ultimate aim is to provide more durable and comprehensive protection against a diverse range of pathogens, thereby significantly reducing the reliance on chemical treatments which often carry environmental and economic costs. Strengthening intrinsic plant immunity represents a sustainable long-term solution.

While the scientific breakthroughs are impressive, a holistic understanding of genome editing for disease resistance must also consider regulatory and societal aspects [6, 8, 10]. A comprehensive overview of CRISPR-Cas technology not only covers diverse strategies but also addresses the complex regulatory landscape and critical public acceptance challenges that must be navigated for successful implementation [6]. The application of these technologies requires careful consideration of ethical implications and public perception to ensure responsible deployment. Realizing the full potential of these transformative tools in sustainable agriculture necessitates a thorough understanding and responsible navigation of these complex, interconnected factors [10]. Balancing innovation with safety, accessibility, and societal acceptance is key to truly transforming crop protection and ensuring future food security.
