Manipulating Unisexual-Sexual Reproduction Transition to Engineer Genome-Reconstructed Polyploids. [PDF]

Adv Sci (Weinh)
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.

Spatio-Temporal Patterns of Hybridization in an Alloploid Salamander (Ambystomatidae: Ambystoma) and Conservation Implications of Introgression in a Unisexual Vertebrate. [PDF]

Ecol Evol
Here we investigate a gynogenetic allopolyploid triploid, the Silvery Salamander (LJJ—historically referred to as Ambystoma platineum), an asexual lineage. However, in our focal populations, neither parental species is present, and another sexual host, A. texanum (TT), is a required sperm donor.

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

Acta 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 ...

Influence of Polyamines on Red Beet (Beta vulgaris L. ssp. vulgaris) Gynogenesis

Agronomy, 2023
The influence of polyamines (PAs), putrescine (Put) and spermidine (Spd) on the efficiency of gynogenesis in ovule cultures of red beet (syn. beetroot) (Beta vulgaris L. vulgaris) cultivar “Czerwona Kula” and breeding accessions no. 3/2010 and no. 7/2008

Genotypic Males Play an Important Role in the Creation of Genetic Diversity in Gynogenetic Gibel Carp

Frontiers in Genetics, 2021
Unisexual lineages are commonly considered to be short-lived in the evolutionary process as accumulation of deleterious mutations stated by Muller’s ratchet.

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

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

Aquaculture 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.

Efficiency of three haplomethods in durum wheat (Triticum turgidum subsp. durum Desf.): isolated microspore culture, gynogenesis and wheat × maize crosses

Czech Journal of Genetics and Plant Breeding, 2019
This study presents the first report comparing the efficiency of microspore culture, gynogenesis and durum wheat × maize crosses for haploid plant production from three durum wheat genotypes (Razzek, Karim and Jneh Khotifa).

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

Animals, 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 ...
