Sequence diversity in the tetraploid Zea perennis and the closely related diploid Z. diploperennis: insights from four nuclear loci.
Polyploidy has been an extremely common phenomenon in the evolutionary history of angiosperms. Despite this there are few data available to evaluate the effects of polyploidy on genetic diversity and to compare the relative effects of drift and selection in polyploids and related diploids. We investigated DNA sequence diversity at four nuclear loci (adh1, glb1, c1, and waxy) from the tetraploid...
متن کاملChromosomes in Hybrids between Euchlaena Perennis and Zea
Hybrids between maize (Zea mays L.) and perennial teosinte (EuMaena perennis Hitchc.) offer a favorable opportunity to follow the behavior of triplicate sets of chromosomes in a triploid hybrid. Maize, the diploid parent, has been carefully analyzed both genetically and cytologically. Perennial teosinte seems to be unquestionably a true tetraploid. Its tetraploid character is evident from (1) t...
متن کاملEcogeography of teosinte
Adaptation of crops to climate change has motivated an increasing interest in the potential value of novel traits from wild species; maize wild relatives, the teosintes, harbor traits that may be useful to maize breeding. To study the ecogeographic distribution of teosinte we constructed a robust database of 2363 teosinte occurrences from published sources for the period 1842-2016. A geographic...
متن کاملMolecular Evidence for a Missing Wild Relative of Maize and the Introgression of Its Chloroplast Genome into Zea Perennis.
The unequivocal documentation fintrogression can be a difficult task because alternative hypotheses, uch as convergence or joint retention of the ancestral condition, are difficult todisprove. Similarly, the direction of introgression between two species can often be inferred, but more rarely proven. Molecular markers offer perhaps the best means of demonstrating introgression, because they are...
متن کاملZea systematics: ribosomal ITS evidence.
Ribosomal internal transcribed spacer (ITS) sequences were used to evaluate the phylogenetics of Zea and Tripsacum. Maximum likelihood and polymorphism parsimony were used for phylogenetic reconstructions. Zea ITS nucleotide diversity was high compared to other plant species, but approximately equivalent to other maize loci. Coalescence of ITS alleles was rapid relative to other nuclear loci; h...
