A Eurasia-wide polyploid species complex involving 6x Trifolium ambiguum, 2x T. occidentale and 4x T. repens produces interspecific hybrids with significance for clover breeding

BMC Plant Biology, 2019
Background Trifolium ambiguum occurs as a 2x, 4x, 6x polyploid series in W Asia. The 6x form is the most agronomically desirable, having strong rhizomatous spread and drought tolerance.

Automictic Reproduction in Interspecific Hybrids of Poeciliid Fish [PDF]

, 2007
SummaryAutomixis, the process whereby the fusion of meiotic products restores the diploid state of the egg, is a common mode of reproduction in plants but has also been described in invertebrate animals [1, 2].

Studies on Colchicine Induced Chromosome Doubling for Enhancement of Quality Traits in Ornamental Plants

Plants, 2019
Polyploidy has the utmost importance in horticulture for the development of new ornamental varieties with desirable morphological traits referring to plant size and vigor, leaf thickness, larger flowers with thicker petals, intense color of leaves and ...

Implications of hybridisation and cytotypic differentiation in speciation assessed by AFLP and plastid haplotypes : a case study of Potentilla alpicola La Soie [PDF]

, 2012
Background: Hybridisation is presumed to be an important mechanism in plant speciation and a creative evolutionary force often accompanied by polyploidisation and in some cases by apomixis. The Potentilla collina group constitutes a particularly suitable

Colchicine induced manifestation of abnormal male meiosis and 2n pollen in Trachyspermum ammi (L.) Sprague (Apiaceae)

Caryologia, 2021
Unreduced gametes are the key source for the natural polyploidization in plants, but process of its formation is very low in nature. Meiotic mutants are second source for the formation of 2n pollen.

Plant speciation through chromosome instability and ploidy change: Cellular mechanisms, molecular factors and evolutionary relevance

Current Plant Biology, 2014
Plant speciation and diversification strongly rely on structural changes in the nuclear genome, both at the whole ploidy and individual chromosome level.
