Rapid identification of inflorescence type markers by genotyping-by-sequencing of diploid and triploid F1 plants of Hydrangea macrophylla

open access: yesBMC Genetics, 2019
Background The ornamental crop Hydrangea macrophylla develops highly attractive lacecap (wild type) or mophead inflorescences. The mophead trait, which is mostly favored by consumers, is recessively inherited by the INFLORESCENCE TYPE locus (INF).

Taxonomy and nomenclature of Rubus ser. Glandulosi (Rosaceae) across its Eurasian range: Revised concepts and new approaches

open access: yesTAXON, Volume 74, Issue 5, Page 1106-1152, October 2025.
Abstract Rubus ser. Glandulosi is one of the most taxonomically intricate taxa of the genus, which is by itself considered a taxonomical nightmare. Around 46 species are currently recognised in the group, but most of its morphological diversity could not be classified at the species level until recently due to unclear reproductive patterns, high ...

Ploidy levels and reproductive behaviour in invasive Hieracium pilosella in Patagonia [PDF]

open access: yes, 2011
Within a population of invasive Hieracium pilosella in Chilean Patagonia we found two ploidy levels, pentaploid and hexaploid. Each ploidy level was represented by one clone.

Manipulating Unisexual–Sexual Reproduction Transition to Engineer Genome‐Reconstructed Polyploids

open access: yesAdvanced Science, Volume 12, Issue 33, September 4, 2025.
This study developed an efficient approach to generate genome‐reconstructed polyploids involving unisexual gynogenetic Carassius gibelio, sexual C. auratus, and sexual C. cuvieri. The selected superior clone inherited gynogenesis ability of C. gibelio and herpesvirus resistance of wild C.

Interspecific hybridization in the genus Hieracium s. str.: evidence for bidirectional gene flow and spontaneous allopolyploidization [PDF]

open access: yes, 2018
Although reticulation has indisputably played an important role in the evolutionary history of the genus Hieracium s. str. (Asteraceae), convincingly documented cases of recent interspecific hybridization are very rare.

Effective Size of Auto-tetraploid Population Under Partial Selfing [PDF]

open access: yes, 2015
Effective population size is defined as the number of breeding individual in an idealized population that would show the same amount of dispersion of allele frequencies under random genetic drift or the same amount of inbreeding as the population under ...

Dynamics of male meiotic recombination frequency during plant development using Fluorescent Tagged Lines in Arabidopsis thaliana [PDF]

open access: yes, 2017
Meiotic homologous recombination plays a central role in creating genetic variability, making it an essential biological process relevant to evolution and crop breeding.

Gametic configuration and inheritance of SSR markers in tetraploid interspecific and intergeneric citrus somatic hybrids : S02P20 [PDF]

open access: yes, 2012
Citrus somatic hybridization has become an integral part of citrus improvement programs worldwide. More than 100 somatic hybrids have been created by Cirad.

Angiosperm polyploids and their road to evolutionary success [PDF]

open access: yes, 2010
The abundance of polyploidy among flowering plants has long been recognized, and recent studies have uncovered multiple ancient polyploidization events in the evolutionary history of several angiosperm lineages.
