“…40,41 Among several plant infection virus families, the Geminiviridae family is an important cause of plant diseases, threatening production by causing severe damage to several commercially valuable crops. 42,43 Among the different strains of the geminiviruses, the Cassava mosaic virus is considered one of the most harmful viruses, losing over 25 million tons of crops annually in Africa, India, and Sri Lanka. 44 Additionally, the high mutation rate of geminiviruses, compared to ssRNA viruses, establishes them as the predominant plant pathogens.…”

The field of nucleic acid therapeutics has witnessed a significant surge in recent times, as evidenced by the increasing number of approved genetic drugs. However, current platform technologies containing plasmids, lipid nanoparticle-mRNAs, and adeno-associated virus vectors encounter various limitations and challenges. Thus, we are devoted to finding a novel nucleic acid vector and have directed our efforts toward investigating circular single-stranded DNA (CssDNA), an ancient form of nucleic acid. CssDNAs are ubiquitous, but generally ignored. Accumulating evidence suggests that CssDNAs possess exceptional properties as nucleic acid vectors, exhibiting great potential for clinical applications in genetic disorders, gene editing, and immune cell therapy. Here, we comprehensively review the discovery and biological effects of CssDNAs as well as their applications in the field of biomedical research for the first time. Undoubtedly, as an ancient form of DNA, CssDNA holds immense potential and promises novel insights for biomedical research.

“…The cultivars of chilli are susceptible to a wide array of pathogens and diseases. Among the important biotic factors that limit the productivity of chilli crops in various regions of the globe are begomoviruses and phytoplasma (Pandey et al, 2022; Mishra et al, 2022; Lavanya and Arun, 2021; Pandey et al, 2021; Mishra et al, 2020; Kumari et al, 2019, Ganefianti et al, 2017)‥ In the chilli plant, infection of begomovirus has been described in distinct states of India and was revealed to cause severe yielding loss (Khan and Khan, 2017). Symptoms of varying severity were observed in plants, ranging from vein yellowing of leaves, mosaic, mottling, stunting, curling, flower abortion, distortion, and small-unvendible fruits reported in Rojas et al, 2018 study.…”

Molecular computing was used to investigate the possible causal agents of chilli crop samples showing mixed symptoms of yellow leaf curl and little leaf type diseases in the Uttar Pradesh province, India. Total genomic DNA was extracted from twenty-five samples and amplified by PCR using a universal primer pair for begomovirus and phytoplasma. Mixed infection samples show positive amplified products for begomovirus (DNA-A and betasatellite) and phytoplasma (16S rRNA and Sec A). The identified begomovirus from chilli samples was identified as a strain isolate of the previously described Chilli Leaf Curl Virus (94.2% nucleotide sequence identity), which is known to infect Solanum lycopersicon, in Oman, whereas the 16S rRNA was identified from the source Candidatus Phytoplasma trifolii (99.04% nucleotide sequence identity), which is known to infect Helichrysum flowering plants in India. Subsequently, molecular computing research based on phylogenetic interweaves, putative recombination, amino acid selection, and genetic diversity were investigated, revealing divergent evolutionary patterns with significant variation and recombination events. The majority of the sequence variations observed in begomovirus and phytoplasma were caused via inter- and intra-specific recombination. These findings could be the first in silico combined infection analysis of ChiLCV and Ca.P.trifolii in a chilli crop in India, revealing the potential adaption and evolution of begomovirus and phytoplasma to a new geographic range and crop.

“…DNA-A is the part that makes proteins responsible for functions like replicating the virus, encapsidation of both genomic molecules and viral gene expression regulation. However, DNA-B creates the protein responsible for the mechanism of viral DNA molecules in and among the host cells [13]. DNA-A components in the genomes can replicate autonomously.…”

Begomovirus has become a potential threat to the agriculture sector. It causes significant losses to several economically important crops. Given this considerable loss, the development of tools to study viral genomes and function is needed. Infectious clones approaches and applications have allowed the direct exploitation of virus genomes. Infectious clones of DNA viruses are the critical instrument for functional characterization of the notable and newly discovered virus. Understanding of structure and composition of viruses has contributed to the evolution of molecular plant pathology. Therefore, this review provides extensive guidelines on the strategy to construct infectious clones of Begomovirus. Also, this technique’s impacts and benefits in controlling and understanding the Begomovirus infection will be discussed.
