Visualization and Interpretation of Plant Isozymes
TLDR
Data retrieved from electrophoretic gels consist of the number and relative mobilities of various enzyme products, which with appropriate genetic analyses become transformed into single or multilocus genotypes for each individual analyzed. Expand
Ribosomal ITS sequences and plant phylogenetic inference.
TLDR
Despite the near-universal usage of ITS sequence data in plant phylogenetic studies, its complex and unpredictable evolutionary behavior reduce its utility for phylogenetic analysis, and it is suggested that more robust insights are likely to emerge from the use of single-copy or low-copy nuclear genes. Expand
Polyploidy and the Evolutionary History of Cotton
TLDR
Allopolyploid cottons appear to have arisen within the last million years, as a consequence of trans-oceanic dispersal of an A-genome taxon to the New World followed by hybridization with an indigenous D- genome diploid. Expand
Molecular marker-facilitated investigations of quantitative trait loci in maize. II. Factors influencing yield and its component traits
TLDR
Numbers and genomic distribution of genetic factors involved in the expression of yield and other quantitatively inherited traits can be elucidated and should prove to be useful for manipulating QTL's in marker-facilitated selection programs. Expand

  • 2004
TLDR
Processes and mechanisms of gene and genome evolution in polyploids are reviewed, including the role of transposable elements in structural and regulatory gene evolution; processes and significance of epigenetic silencing; underlying controls of chromosome pairing and mechanisms and functional significance of rapid genome changes are reviewed. Expand
Divergent Evolution of Plant NBS-LRR Resistance Gene Homologues in Dicot and Cereal Genomes
TLDR
The results suggest that the two main groups of resistance genes underwent divergent evolution in cereal and dicot genomes and imply that their cognate signaling pathways have diverged as well. Expand
Genes duplicated by polyploidy show unequal contributions to the transcriptome and organ-specific reciprocal silencing
TLDR
Data suggest that some silencing events are epigenetically induced during the allopolyploidization process, suggesting rapid subfunctionalization in eukaryotes. Expand
Repeated polyploidization of Gossypium genomes and the evolution of spinnable cotton fibres
TLDR
It is shown that an abrupt five- to sixfold ploidy increase approximately 60 million years (Myr) ago, and allopolyploidy reuniting divergent Gossypium genomes approximately 1–2 Myr ago, conferred about 30–36-fold duplication of ancestral angiosperm genes in elite cottons, genetic complexity equalled only by Brassica among sequenced angiosperms. Expand
Polyploidy and genome evolution in plants.
TLDR
Evidence is now supported by evidence showing that genes that are retained in duplicate typically diversify in function or undergo subfunctionalization, with some duplicate genes more prone to retention than others. Expand
Bidirectional interlocus concerted evolution following allopolyploid speciation in cotton (Gossypium).
TLDR
This study demonstrates that the process occurs for tandemly repeated sequences in diploid and polyploid plants and that interlocus concerted evolution can occur bidirectionally subsequent to hybidization andpolyploidization, which has significant implications for phylogeny reconstruction. Expand
