Diversity of Improved Diploids and Commercial Triploids from Musa spp. via Molecular Markers

Current Issues in Molecular Biology
Banana breeding consists of obtaining diploid, triploid, and tetraploid intra- and interspecific hybrids by conventional breeding methods with the objective of aggregating characteristics of agronomic and commercial interest.

Phylogenetic Structure of Plant Communities: Are Polyploids Distantly Related to Co-occurring Diploids?

Frontiers in Ecology and Evolution, 2018
Polyploidy is widely acknowledged to have played an important role in the evolution and diversification of vascular plants. However, the influence of genome duplication on population-level dynamics and its cascading effects at the community level remain ...

In vitro germination and viability of pollen grains of banana diploids [PDF]

Crop Breeding and Applied Biotechnology, 2008
The objective of this study was to evaluate the influence of pH on in vitro germination and pollen grain viability of banana diploids (AA) generated by the breeding program of Embrapa Mandioca e Fruticultura Tropical. The pollen grains were inoculated in

Eco‐genetic additivity of diploids in allopolyploid wild wheats [PDF]

, 2020
Underpinnings of the distribution of allopolyploid species (hybrids with duplicated genome) along spatial and ecological gradients are elusive. As allopolyploid speciation combines the range of genetic and ecological characteristics of divergent diploids,

On the Genealogy of Asexual Diploids [PDF]

Journal of Computational Biology, 2010
Abstract Given molecular genetic data from diploid individuals that, at present, reproduce mostly or exclusively asexually without recombination, an important problem in evolutionary biology is detecting evidence of past sexual reproduction (i.e., meiosis and mating) and recombination (both meiotic and mitotic ...

Pollen Development and Viability in Diploid and Doubled Diploid Citrus Species

Frontiers in Plant Science, 2022
Seedlessness is one of the most important agronomic traits in mandarins on the fresh fruit market. Creation of triploid plants is an important breeding strategy for development of new commercial varieties of seedless citrus. To this end, one strategy is to perform sexual hybridizations, with tetraploid genotypes as male parents.

Uniparentality: advantages for range expansion in diploid and diploid-autopolyploid species

Botanical Journal of the Linnean Society, 2022
AbstractUniparental reproduction, the capacity of an individual to produce offspring autonomously, is expected to facilitate range expansion of populations. Paspalum spp. reproduce uniparentally by sexual (self-fertility) and asexual (apomixis) reproduction and biparentally by sexual (self-sterility) reproduction.

Glutamine synthetase subunit mixing and regulation in Bacillus subtilis partial diploids [PDF]

, 1982
A specialized transducing phage, SPβ c2 dglnA2, of Bacillus subtilis was used to construct partial diploids with various glutamine auxotrophs. The overproduction of manganese-stimulated glutamine synthetase no longer occurred in the diploids.

Expression of wtf4^antidote promoter reporters in diploids and asci.

, 2022
Depictions and images of the two lengths of wtf4antidote promoters used in this study, pantidote (A) and pantidote long (B). The images of the two different pantidote-mCherry reporters / + were from heterozygous diploids and asci.

The hidden threat: genetic load dynamics in tetraploids and diploids. [PDF]

Evol Lett
Polyploids are organisms with three or more chromosome sets, which often give them different physiology, morphology, and evolutionary properties. The impact of polyploidy on the genetic load dynamics, in terms of accumulation, fixation, and purging of ...
