I think the reader will agree that we have attained a good balance
in Volume 6 between human-or animal-host and plant-host-related
topics from outstanding research scientists. In Chapter 1, Frank
Collins, Susan Paskewitz, and Victoria Finnerty explore the
potential of recombinant DNA technology to distinguish indi vidual
species and to establish phylogenetic relationships among member
species in the Anopheles gambiae species complex, which includes
the principal malaria vectors. Currently, relatively little is
known about these morphologically identical species that are
sympatric over most of their range but are not always equally
involved in malaria transmission. With respect to individual
species identification, the researchers have thus far described two
DNA fragments, derived from the ribosomal DNA interge nic spacer
region, that reliably distinguish five species in the complex by
means of an RFLP visualized on a Southern blot. They have also
described other species-specific fragments derived from a ribosomal
DNA intron that could form the basis for a rapid dot blot assay.
With respect to the phylogenetic relationships among member species
in the complex, Collins, Paskewitz, and Finnerty focus on a
comparison at the level of restriction site mapping and Southern
analysis of the rDNA intergenic spacer regions. As expected, the
two spacer regions near the coding region junctions are well
conserved among the species, whereas the central regions tend to be
highly variable among member species in the complex."
