Doubled Haploids: Contributions of Poland’s Academies in Recognizing the Mechanism of Gametophyte Cell Reprogramming and Their Utilization in Breeding of Agricultural and Vegetable Species

open access: yesActa Societatis Botanicorum Poloniae, 2022
Diverse processes leading to doubled haploid (DH) plant production, such as microspore embryogenesis, gynogenesis, and distant hybridization followed by genome elimination, are based on the unique ability of plant cells to form haploid embryos without ...

Comparison of different ploidy detection methods in Oncorhynchus mykiss, the rainbow trout

open access: yesFisheries and Aquatic Sciences, 2017
The objective of this study was to determine a simple and reliable ploidy identification protocol for the rainbow trout (RT), Oncorhynchus mykiss, in the field condition. To evaluate the ploidy level and compare different detection protocols, triploid RT

Induction of gynogenesis by heterogenous sperm and cold shock treatment in Epinephelus fuscoguttatus

open access: yesReproduction and Breeding, 2021
Gynogenesis is a chromosome set manipulation technique to accelerate inbred lines used for genomics analysis and genetic breeding. Groupers are hermaphroditic fish whereby they sexually mature as females and subsequently change sex to male. Production of

Induction of gynogenesis with ultra-violet irradiated Koi carp (Cyprinus carpio haematopterus) sperm demonstrates the XX/XY sex determination system in Opsariichthys bidens

open access: yesAquaculture Reports, 2022
Opsariichthys bidens (Chinese hooksnout carp) is a small stream fish with high economic value. As the males of this species grow faster than females, it follows that mono-sex breeding has significant potential for commercial production.

Preliminary Identification of Candidate Genes Related to Survival of Gynogenetic Rainbow Trout (Oncorhynchus mykiss) Based on Comparative Transcriptome Analysis

open access: yesAnimals, 2020
In the present research, the eggs from four rainbow trout females were used to provide four groups of gynogenetic doubled haploids (DHs). The quality of the eggs from different clutches was comparable, however, interclutch differences were observed in ...
