Abstract:
Recent research describing the strain-specific mechanisms underlying experimental CTV superinfection exclusion has far-reaching implications for the manner in which cross-protecting sources should be selected for. The strain composition of both cross-protecting sources and field populations needs to be sufficiently characterized to improve control of severe stem-pitting and decline isolates. Many of the biological, serological, and molecular techniques used in previous studies yield very limited information about the strain composition of populations and the relative titer of their components. In this chapter we describe a protocol for the characterization of CTV populations, based on the use of the next-generation sequencing Illumina MiSeq platform of p33 gene amplicons.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
