TL;DR: Factors driving the emergence and establishment of whitefly-transmitted diseases include genetic changes in the virus through mutation and recombination, changes inThe vector populations coupled with polyphagy of the main vector, Bemisia tabaci, and long distance traffic of plant material or vector insects due to trade of vegetables and ornamental plants.

TL;DR: Revised guidelines for the classification and nomenclature of begomoviruses are proposed and genome-wide pairwise identities of 91 % and 94 % are proposed as the demarcation threshold for begomviruses belonging to different species and strains, respectively.

TL;DR: The geminiviruses are a family of small, non-enveloped viruses with single-stranded, circular DNA genomes of 2500–5200 bases causing economically important diseases in most tropical and subtropical regions of the world.

TL;DR: An overview of the most outstanding achievements in the research on the TYLCV complex that could lead to more effective control strategies is provided.

TL;DR: Analysis of ES421/99 showed that it exhibited a novel pathogenic phenotype that might provide it with a selective advantage over the parental genotypes, and agrees with results from field studies which revealed that the recombinant strain is becoming prevalent in the region in which it was detected.
