Major botanical advances often suffer the worst of fates±the scienti® c community ignores
them until they are independentlydiscovered'or con® rmed by zoologists. For example, the …

Molecular data have had a profound impact on the field of plant systematics, and the
application of DNA-sequence data to phylogenetic problems is now routine. The majority of …

A short account of the development of classical genome analysis, the analysis of
chromosome behaviour in metaphase I of meiosis, primarily in interspecific hybrids, is given …

The current approaches to the study of clonal plants are reviewed. Most studies concentrate
at the level of the ramet and clonal fragment exploring the “microscopic” view of clonal …

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

Studies of character evolution have frequently relied on ahistorical correlations rather than
on phylogenies. However, correlations do not estimate the number of times that a trait …

Enzyme electrophoresis and restriction‐fragment analysis of chloroplast DNA (cpDNA) and
nuclear ribosomal DNA (rDNA) were used to test the hypothesis that both Helianthus …

Early in speciation, as populations undergo the transition from local adaptation to incipient
species, is when a number of transient, but potentially important, processes appear to be …

Linkage analysis and map construction using molecular markers is far more complicated in
full-sib families of outbreeding plant species than in progenies derived from homozygous …

In situ hybridization enabled DNA originating from the two parental genomes to be
distinguished in plant hybrids. A probe of biotinylated total genomic DNA from Secale …
