“…Evolutionary analysis indicates that BVYMV evolve from sub-continent. Evolutionary analysis of BVYMV and its vector (Whitefly) reveals great compatibility, several strains and species emerges which results in great diversity of this virus (Ong et al, 1980) Trade between two countries is also a factor of introduction of SMV into new locality (Rajamaki et al, 2009). Phylogenetic analysis of SMV indicates that it has great diversity.…”

The Chickpea Chlorotic Dwarf Virus (CpCDV) has proved very much devastating not only for chickpea crop but also for lentils, cotton and papaya. In recent past years, this mastrevirus put a sublime pressure on hosts and reduced yield up to 95%. This virus is most prevalence in dry regions and equally important pathogen in other parts of the world especially in America and Europe. This capability is due to rapid changes in DNA. Vector species also play important role in spread of this virus. Here evolutionary study of 20 genomes was done. All genomes obtained from cotton and lentil crop. Genomes obtained from lentil crop are ancestors and rest are offsprings. According to our finding, CpCDV is very important pathogen not only for Fabaceae family but also for Malvaceae family.

The chilli ring spot virus (ChiRSV) is one of the most important virus of chilli crop in Southeast Asia and China. Chilli ring spot virus (ChiRSV) is most devastating virus not only for chilli crop but also for solanaceous crops. In severe cases, up to 100% yield losses have been observed in chilli crop. A large virus vector population spreads this disease throughout Southeast Asia and China. The diversity of this Potyvirus is proven after examination of many samples isolated from different locations in China and Vietnam, which shows the virus is successfully prevalent in that part of the world. The phylogenetic investigation of this potyvirus included 11 full size samples in total. Phylogenetic study of different samples indicates that two sequences (KT633930, KX379001) are ancestors of all sequences and others are descendants. Later on, with the passage of time, these sequences (KT633930, KX379001) evolve and different strains, variants and species arrived. Recombination analysis shows that there is no recombination in any sequence and all sequences are quite unique. We also determined replacement frequencies for Potyviruses. According to our findings, ChiRSV is very important pathogen for not only Solanaceae family but also for other crops because of its presence on different other host plants.

“…Two different insertion sites in potyviruses were exploited for the introduction of target genes, either between P1 and HC-Pro or else between NIb and capsid protein cistrons [ 86 ]. These criteria allowed a simultaneous expression of two foreign proteins [ 87 ], either as free molecules or fused to viral proteins [ 88 , 89 ].…”

Numerous potyvirus studies, including virus biology, transmission, viral protein function, as well as virus–host interaction, have greatly benefited from the utilization of reverse genetic techniques. Reverse genetics of RNA viruses refers to the manipulation of viral genomes, transfection of the modified cDNAs into cells, and the production of live infectious progenies, either wild-type or mutated. Reverse genetic technology provides an opportunity of developing potyviruses into vectors for improving agronomic traits in plants, as a reporter system for tracking virus infection in hosts or a production system for target proteins. Therefore, this review provides an overview on the breakthroughs achieved in potyvirus research through the implementation of reverse genetic systems.
