▪ Abstract Populations of plant viruses, like all other living beings, are genetically
heterogeneous, a property long recognized in plant virology. Only recently have the …

The genus Crinivirus includes the whitefly-transmitted members of the family
Closteroviridae. Whitefly-transmitted viruses have emerged as a major problem for world …

Cucurbit crops may be affected by at least 28 different viruses in the Mediterranean basin.
Some of these viruses are widely distributed and cause severe yield losses while others are …

We examined the population structure and genetic variation of four genomic regions within
and between 30 Citrus tristeza virus (CTV) isolates from Spain and California. Our analyses …

RNA viruses are characterized by high genetic variability resulting in rapid adaptation to
new or resistant hosts. Research for plant RNA virus genetic structure and its variability has …

▪ Abstract Like many other plant RNA viruses, Wheat streak mosaic virus (WSMV) sequence
diversity within and among infected plants is low given the large number of virions produced …

Whiteflies are a key pest of crops in open-field production throughout the tropics and
subtropics. This is due in large part to the long and diverse list of devastating plant viruses …

RNA viruses have a great potential for genetic variation, rapid evolution and adaptation.
Characterization of the genetic variation of viral populations provides relevant information on …

Viruses transmitted by the sweet potato whitefly (Bemisia tabaci) have been detrimental to
the sustainable production of cucurbits in the southeastern USA. Surveys were conducted in …

Mixed virus infection in host plants can differentially alter the plant phenotype, influence
vector fitness, and affect virus acquisition and inoculation by vectors than single-virus …
