In this review, encouraged by the dictum of Theodosius Dobzhansky that “Nothing in biology
makes sense except in the light of evolution”, we outline the likely evolutionary pathways …

Background Potyviruses are found world wide, are spread by probing aphids and cause
considerable crop damage. Potyvirus is one of the two largest plant virus genera and …

Potyviruses are the largest group of plant infecting RNA viruses that cause significant losses
in a wide range of crops across the globe. The majority of viruses in the genus Potyvirus are …

Potyviridae is the largest family of plant-infecting RNA viruses, encompassing over 30% of
known plant viruses. The family is closely related to animal picornaviruses such as …

Understanding the molecular biology of viruses and the functions of the various proteins
expressed by their genome is a prerequisite for the control of virus propagation and the …

The potyviruses are one of the two most speciose taxa of plant viruses. Our expanded
knowledge of the breadth and depth of their diversity and its origins has depended greatly …

There are two major requirements for potyvirus taxonomy; group-specific criteria and criteria
which discriminate between distinct viruses and strains. This review discusses the relative …

Recent knowledge of the structure of the potyvirus particle and its components appears to
have resolved what was thought to be an intractable problem of plant virology. This review …

Local areas of conserved amino acid sequence in the replicase and coat proteins of
potyviruses were used to select nucleotide sequences for use in the construction of sets of …

Three degenerate primers, located at the NIb and CP gene regions, were designed for
potyvirus detection. Using these primer pairs, 1.0–1.2 kb cDNA fragments of the 3′-terminal …
