FHY3/FAR1 transposable elements generate adaptive genetic variation in the Bassia scoparia genome
Pest Management Science, EarlyView.FHY3/FAR1 are active transposable elements and are involved with the formation of genomic structural variants that cause glyphosate resistance in Bassia scoparia. Abstract BACKGROUND A nearly complete genome assembly consisting of 14 scaffolds, a total length of 969.6 Mb, and an N50 scaffold length of 99.88 Mb, was generated to better understand how ...

Statistical Inference of Allopolyploid Species Networks in the Presence of Incomplete Lineage Sorting [PDF]
arXiv, 2012 Polyploidy is an important speciation mechanism, particularly in land plants. Allopolyploid species are formed after hybridization between otherwise intersterile parental species. Recent theoretical progress has led to successful implementation of species tree models that take population genetic parameters into account.

mTORC1 regulates cytokinesis through activation of Rho-ROCK signaling [PDF]
arXiv, 2015 Understanding the mechanisms by which cells coordinate their size with their ability to divide has long attracted the interest of biologists. The Target of Rapamycin (TOR) pathway is becoming increasingly recognized as a master regulator of cell size, however less is known how TOR activity might be coupled with the cell cycle.

TAXON, EarlyView.Abstract We explored the diversification of the south‐eastern and eastern European Euphorbia agraria s.l. applying molecular (amplified fragment length polymorphism [AFLP] fingerprinting and sequencing of the nuclear ribosomal internal transcribed spacer [ITS]), cytogenetic (relative genome size [RGS] estimations) and morphometric methods.

The Evolutionary Consequences of Polyploidy [PDF]
Cell, 2007 Polyploidization, the addition of a complete set of chromosomes to the genome, represents one of the most dramatic mutations known to occur. Nevertheless, polyploidy is well tolerated in many groups of eukaryotes. Indeed, the majority of flowering plants and vertebrates have descended from polyploid ancestors.

Plant Species Biology, EarlyView.Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.

Weedy Adaptation in Setaria spp.: VI. S. faberi Seed hull shape as soil germination signal antenna [PDF]
arXiv, 2014 Ecological selection forces for weedy and domesticated traits have influenced the evolution of seed shape in Setaria resulting in similarity in seed shape that reflects similarity in ecological function rather than reflecting phylogenetic relatedness. Seeds from two diploid subspecies of Setaria viridis, consisting of one weedy subspecies and two races

Crop Journal, 2023 Heterosis and polyploidy have an overwhelming influence on plant evolution. Recently, polyploid rice hybrids have been used to breed new rice varieties because they combine the advantages of both heterosis and polyploidy.

Nature, 1958 IN my preliminary account1 on polyploidy in bluebells (Endymion nonscriptus (L.) Garcke, and E. hispanicus (Mill) Chouard), I mentioned that some of the huge forms in gardens which I found to be triploids looked very much like the central one of Turrill's coloured figures2.
