Abstract
Plants are susceptible to phytopathogens, including bacteria, fungi, and viruses, which cause colossal financial shortfalls (pre- and post-harvest) and threaten global food safety. To combat with these phytopathogens, plant possesses two-layer of defense in the form of PAMP-triggered immunity (PTI), or Effectors-triggered immunity (ETI). The understanding of plant-molecular interactions and revolution of high-throughput molecular techniques have opened the door for innovations in developing pathogen-resistant plants. In this context, Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR-associated protein 9 (Cas9) has transformed genome editing (GE) technology and being harnessed for altering the traits. Here we have summarized the complexities of plant immune system and the use of CRISPR-Cas9 to edit the various components of plant immune system to acquire long-lasting resistance in plants against phytopathogens. This review also sheds the light on the limitations of CRISPR-Cas9 system, regulation of CRISPR-Cas9 edited crops and future prospective of this technology.
期刊介绍:
GM Crops & Food - Biotechnology in Agriculture and the Food Chain aims to publish high quality research papers, reviews, and commentaries on a wide range of topics involving genetically modified (GM) crops in agriculture and genetically modified food. The journal provides a platform for research papers addressing fundamental questions in the development, testing, and application of transgenic crops. The journal further covers topics relating to socio-economic issues, commercialization, trade and societal issues. GM Crops & Food aims to provide an international forum on all issues related to GM crops, especially toward meaningful communication between scientists and policy-makers.
GM Crops & Food will publish relevant and high-impact original research with a special focus on novelty-driven studies with the potential for application. The journal also publishes authoritative review articles on current research and policy initiatives, and commentary on broad perspectives regarding genetically modified crops. The journal serves a wide readership including scientists, breeders, and policy-makers, as well as a wider community of readers (educators, policy makers, scholars, science writers and students) interested in agriculture, medicine, biotechnology, investment, and technology transfer.
