RNA viruses are responsible for numerous animal diseases, leading to significant economic impact on the livestock and poultry industry. A safe and effective method to generate broad and long-lasting immunity against these viruses is challenging, necessitating the development of reverse genetics technologies. Reverse genetics is vital in vaccine development, allowing precise modification of viral genomes to create safer and more effective vaccines. Its significance lies in enabling rapid vaccine generation, tailoring vaccines to specific viral strains, creating multivalent vaccines, ensuring vaccine safety, studying immune responses, and developing novel vaccine platforms. Overall, reverse genetics revolutionizes vaccine development by providing unprecedented control over viral genomes, leading to safer, more effective, and tailored vaccines against various infectious diseases. Bioinformatics plays a crucial role in developing reverse genetics-based vaccine platforms, which manipulate the genetic makeup of an organism to examine the function of specific genetic mutations or markers. Different tools and databases are used to analyse gene sequences, anticipate the consequences of genetic alterations, and create and assess the effectiveness of techniques for introducing those modifications. Computational methods can also be used to interpret and analyse data generated from reverse genetics research, such as transcriptome and proteome profiling, to better understand the functional effect of genetic mutations. It predicts how genetic alterations impact protein structure and function, designs specific oligonucleotides, and facilitates the generation of reverse genetic clones through in silico cloning. Integrating bioinformatics with CRISPR-Cas9 and TALENs improves the efficiency and specificity of these genome editing systems, selecting the most effective guide RNAs to minimize off-target effects and optimizing TALE proteins for precise editing. This chapter delves into current research on developing reverse genetic platforms for vaccine development against RNA viruses in domestic animals, reviews the use of computational tools and methodologies in creating efficient reverse genetic platforms, and discusses the challenges and future directions of this research area.
