polyploidy

Considering that switchgrass is an allotetraploid plant, the gene number of PvARFs in each cluster should be approximately twice than the other monocots, especially in foxtail millet, the most closely relatives to switchgrass among the selected species (Table S2).

The condition of normal diploid segregation in the present case may be met by explaining that though cotton is an amphidiploid (allotetraploid) of A and D genomes [15] it has established itself as genetically stable over the years and behaves as normal diploid in subsequent generations [16].

Dynamics of polyploid formation and establishment in the allotetraploid rock fern Asplenium majoricum.

The mutation may have occurred in one of the subgenomes of the allotetraploid after the polyploidization event.

There appear to be two main players of relevance to Arabian workers: a diploid with entire false indusia, and an allotetraploid with fringed false indusia (Vida et al.

arabica which is an allotetraploid (2n = 4x = 44) species.

These data suggest that all 500+ species are descended from a single allotetraploid ancestor that was derived from two divergent parents.

arenosa to form a stable fertile hybrid allotetraploid, A.

This situation has also been described in the allotetraploid rodent Tympanoctomys barrerae (Lawrence, 1941) (Octodontidae), in which chromosomal material has been eliminated showing a 2n = 102, which is less than the expected 2n = 112 based on its closest relatives (Gallardo et al.

Is Allotetraploid Evolution in Terns a Species Pump?

Also, growth vigor was higher in allotetraploid plants (polyploids formed by combining two different Arabidopsis species) than standard hybrids (formed through combining the same species).

Currently, the stoloniferous, allotetraploid creeping bentgrass (2n = 4x = 28) is the most adapted species for use on golf course fairways and greens (Wipff and Fricker, 2001).

truncatus is an allotetraploid species with a distribution spanning from the South of Africa to the Middle East and the Mediterranean Islands (Brown 1994).

Bulinus truncatus is an allotetraploid species distributed over most of Africa, several Mediterranean islands, and part of the Middle East.

Until now the genome of common millet has not been well-characterized due to its allotetraploid nature.
