“…Australia and Argentina such that it is among the common viruses tested for in seed potato production schemes. Such outbreaks of thrips and whiteflytransmitted viruses are becoming steadily more frequent due to a warming climate, and at least one of these viruses, ToLCNDV has recently become a major potato pathogen in India (Jeevalatha et al 2017a).…”

“…ToLCNDV-[potato] has emerged as a serious threat to potato production during recent times. Its incidence is reported in almost all major potato growing states (Jeevalatha et al 2017a). GBNV is reported in the early planted crop in the central and western parts of India (Jain et al 2004).…”

“…ToLCNDV-[potato] is a bipartite begomovirus with two genomic components referred as DNA-A and DNA-B. The DNA A components of the ToLCNDV-[potato] isolates shared more than 90.0% similarity to ToLCNDV isolates from vegetable crops such as tomato and okra, 89.0-90.0% to papaya isolates and 70.4-74.0% to other ToLCVs (Jeevalatha et al 2017a).…”

Viruses are among the most significant biotic constraints in potato production. In the century since the discovery of the first potato viruses we have learned more and more about these pathogens, and this has accelerated over the last decade with the advent of high-throughput sequencing in the study of plant virology. Most reviews of potato viruses have focused on temperate potato production systems of Europe and North America. However, potato production is rapidly expanding in tropical and subtropical agro-ecologies of the world in Asia and Africa, which present a unique set of problems for the crop and affect the way viruses can be managed. In this chapter we review the latest discoveries in potato virology as well as the changes in virus populations that have occurred over the last 50 years, with a particular focus on countries in the (sub-)tropics. We also review the different management approaches including use of resistance, seed systems, and cultural approaches that have been employed in different countries and reflect on what can be learnt from past research on potato viruses, and what can be expected in the future facing climate change.

“…Com o advento da técnica de amplificação de moléculas de DNA circulares, por meio do uso da DNA polimerase (Haible et al, 2006) do phago phi29, e devido à grande disponibilidade de softwares de bioinformática capazes de detectar regiões recombinantes em genomas virais (Posada, 2002;Martin et al, 2015), o mecanismo evolutivo de recombinação tem sido estudado ao longo dos últimos anos (De Bruyn et al, 2016;Ferro et al, 2017;Jeevalatha et al, 2017;Lima et al, 2017;Mar et al, 2017;Vinoth Kumar et al, 2017). O conhecimento acerca da frequência na qual a recombinação ocorre é essencial, pois populações virais sujeitas à ocorrência frequente de eventos de recombinação possuem maior capacidade adaptativa do que aquelas populações pouco propensas à recombinação (Monci et al, 2002;Prasanna and Rai, 2007;Vuillaume et al, 2011).…”

Populations of plant viruses show high levels of genetic variability due to the evolutionary mechanisms of mutation, recombination and pseudorecombination. As a consequence, viral populations evolve rapidly being able to expand their host ranges and overcome the genetic resistance of plants at a faster rate than populations of other disease-causing agents. Begomoviruses (genus Begomovirus, family Geminiviridae) are highly prone to both intra and interspecific recombination. In fact, several recently published studies indicate that most of the known begomovirus species have a recombinant origin. On the other hand, due to the geographical isolation of begomovirus subpopulations, it is possible that the recombination affects each one in a different extent. In this context, the present study aimed to characterize the recombination patterns in each of the major subpopulations that composes the begomovirus global metapopulation. For this, genomic sequences of begomovirus isolates collected in different locations around the world were obtained from Genbank database and analyzed using computational tools of population genetics. The metapopulation was subdivided into two to eight major subpopulations using a multivariate statistical-based approach. The sequences corresponding to the isolates of each subpopulation were analyzed for the presence and distribution of recombination breakpoints. The results obtained in this study indicate that the major begomovirus subpopulations show distinct recombination dynamics, with an evolutionary isolation determined by their geographic distribution.
